GENERAL
Suspension Spring Pre-Load/Installed Length
When installing springs on shocks the specifications will call out “Installed Length” or “Pre-Load”.
Installed Length is the length of the spring from end to end when it is ready to be installed on the snowmobile. You should adjust
the spring preload ring until you reach your specified spring installed length.
Pre-Load is the amount of space that you have from the bottom of the spring preload adjuster to the top of the spring retainer.

To figure out the correct fuel to oil ratio per gallon, you will need
to use different formulas for the ratio that you are looking for.
Example of a fuel/oil ratio of 20:1 is figured out by taking the
gallons of the fuel mixing container (1 gallon) and converting it
to ounces (128 oz.) divided by the ratio that you are looking for
(20), this will give you the amount of oil that you need (6.4 oz.)
to add to the fuel in the mixing container.

One of the misunderstood properties of gasoline is its volatility,
or ability to vaporize at different ambient temperatures and
altitudes during the year.
When gasoline is blended, it is given a Reid Vapor Pressure
(RVP) number which reflects its ability to vaporize or mix with
air at a given temperature range. Gasoline vapor pressure is
measured by putting a sample of fuel inside a closed container
and applying a specified amount of heat to the container for a
certain amount of time. RVP will vary from about 7.0 PSI during
the summer to approximately 13.5 PSI during the colder
months. Service stations selling a large volume of fuel will
normally have the correct blend to work well at all times
throughout the year in their local area.
When the weather is very cold, gasoline must be able to vaporize
very quickly in order for an engine to start and warm up
properly. If summer blend fuel is being used in the winter, little
or no vaporization will occur. Droplets will form causing
flooding and very hard starting.
If winter blend fuel is being used during the summer months, it
may cause vapor lock (boiling fuel) inside the fuel lines, fuel
pump, or carburetor. This will cause warm engine drive ability
problems and hard starting when warm.
Changing temperature, barometer, altitude, and fuel supply are
just a few of the factors that can affect the day to day
performance of your engine. That is why using Exhaust Gas
Temperatures (EGT) are important for maintaining optimum
performance. There are two methods for helping you determine
what the EGTs are for your machine. Piston wash and the
coloring of your spark plug.The piston wash is by far the most
valuable tool in concluding EGTs, with the spark plug color
running a distant second. Use the illustrations below to help you
establish the EGTs for your machine.
Once the proper jetting is established, you can reference the
EGT gauge for your baseline numbers. Then, if there is a rise or
fall of 25 degrees, you must jet accordingly to return your EGTs
to the baseline numbers.

To ensure many trouble-free miles of snowmobiling enjoyment, follow recommended regular maintenance and service checks
outlined in this manual. The recommended maintenance schedule on your snowmobile calls for service and maintenance inspections
at 150 miles (240 km), 1000 miles (1600 km), and 2000 miles (3200 km). These inspections should be performed by a qualified
service technician. For continued optimum performance and component life, continue maintenance checks at 1000 mile (1600 km)
intervals. All necessary replacement parts and labor incurred, with the exception of authorized warranty repairs, become the
responsibility of the registered owner. If, during the course of the warranty period, part failures occur as a result of owner neglect
in performing recommended regular maintenance, the cost of repairs are the responsibility of the owner.
Personal safety is critical when attempting to service or adjust your snowmobile. If you're not familiar with safe service or adjustment
procedures and the use of tools, or if you don't feel comfortable performing these tasks yourself, contact an authorized Polaris dealer
for service.
The following chart is a guide based on average riding conditions. You may need to increase frequency based on riding conditions.
When inspection reveals the need for replacement parts, always use genuine Polaris parts, available from your Polaris dealer.
Inspect each piston dome area of the cylinder head for warping
by placing a straight edge across the dome area.
With a feeler gauge measure any gap under the straight edge.

Cylinder Measurement
Inspect each cylinder for wear, scratches, or damage. If no
damage is evident, measure the cylinder for taper and out of
round with a telescoping gauge or a dial bore gauge. Measure the
bore .50" from the top of the cylinder; in line with the piston pin
and 90° to the pin to determine if the bore is out of round. Repeat
the measurements at the middle of the cylinder and the bottom
of the cylinder to determine taper or out of round at the bottom.
Use the chart below and record all measurements.

Cylinder Honing
The cylinder bore must be de-glazed whenever new piston rings
are installed. A light honing with fine stones removes only a
very small amount of material. A proper crosshatch pattern is
important to provide a surface that will hold oil, and allow the
rings to seat properly. If the crosshatch is too steep, oil retention
will be reduced. A crosshatch angle which is too shallow will
cause ring vibration, poor sealing, and overheating of the rings
due to blow-by and reduced contact with the cylinder wall.
Service life of the pistons and rings will be greatly reduced.
NOTE: A Nikasil cylinder can be lightly honed with a
soft stone hone but an not be oversized.

MAINTENANCE
Honing Procedure
1.Wash the cylinder with cleaning solvent.
2.Clamp the cylinder in a soft jawed vise by the cylinder
studs.
3.Place hone in cylinder and tighten stone adjusting knob
until stone contacts the cylinder walls (DO NOT
OVERTIGHTEN). Cylinders may be wet or dry honed
depending on the hone manufacturer's recommendations.
Wet honing removes more material faster and leaves a
more distinct pattern in the bore. Using a .50" (13 mm) drill
motor rotating at a speed of 300-500 RPM, run the hone in
and out of the cylinder rapidly until cutting tension
decreases. Remember to keep the hone drive shaft centered
to prevent edge loading and always bring the stone
approximately 2" (1.3 cm) beyond the bore at the end of
each stroke.
4.Release the hone at regular intervals to inspect bore size
and finish.
Honing To Over Size (340/500 Fuji Engines
Only)
If cylinder wear or damage is excessive, it will be necessary to
oversize the cylinder using a new oversize piston and rings. This
may be accomplished by either boring the cylinder and then
finish honing to the final bore size, or by rough honing followed
by finish honing.
Cleaning The Cylinder After Honing
It is very important that the cylinder be thoroughly cleaned after
honing to remove all grit material. Wash the cylinder in a
solvent, then in hot soapy water. Pay close attention to areas
where the cylinder sleeve meets the aluminum casting (transfer
port area). Use electrical contact cleaner if necessary to clean
these areas. Rinse thoroughly, dry with compressed air, and oil
the bore immediately with Polaris Premium 2 Cycle Lubricant.
NOTE: Always check piston to cylinder clearance
and piston ring installed gap after honing or boring
is complete.
Piston Inspection
Check piston for scoring or cracks in piston crown or pin area.
Excessive carbon buildup below the ring lands is an indication
of piston, ring or cylinder wear. For Liberty™ engines, measure
piston outside diameter at a point .375" (10mm) up from the
bottom of the skirt at a 90° angle to the direction of the piston
pin. For Fuji engines, measure piston outside diameter at a point
that is .50" (12.7mm) up form the bottom of the skirt at a 90°
angle to the direction of the piston pin.
For oversize honing always wet hone using honing oil and a
coarse roughing stone. Measure the new piston at room
temperature (see piston measurement) and rough hone to the
size of the piston or slightly larger. Always leave .002" - .003"
(.05 - .07 mm) for finish honing. Complete the sizing with fine
grit stones to provide the proper cross-hatch finish and required
piston clearance.
Inspect cylinder for taper and out-of-round. Taper or out-ofround on the finished bore should not exceed .0004" (.002mm).
NOTE: Portable rigid hones are not recommended
for over sizing cylinders, cylinder boring, and finish
honing. The use of an arbor type honing machine is
recommended. Always check piston to cylinder
clearance and piston ring installed gap after boring/
honing is complete.
NOTE: The piston is measured at this point to
provide an accurate piston to cylinder
measurements.
Subtract this measurement from the minimum cylinder
measurement (90° to the pin) recorded previously when you
recorded the cylinder measurements. If clearance exceeds the
service limit, the cylinder should be re-bored and new pistons
and rings installed. Refer to piston to cylinder clearance limits
in the General Information section listed per model.
3.6
MAINTENANCE
Piston Ring Installed Gap
Position the ring .50" (1.3 cm) from the top of the cylinder using
the piston to push it squarely into place. Measure installed gap
with a feeler gauge at both the top and bottom of the cylinder.
NOTE: A difference in end gap indicates cylinder
taper. The cylinder should be measured for
excessive taper and out of round. Replace rings if
the installed end gap exceeds the service limit.
Always check piston ring installed gap after reboring a cylinder or when installing new rings.
Recommended Coolant
Polaris snowmobiles use a premium 60/40 pre-mix antifreeze.
This premium antifreeze is mixed with deionized water for
better protection for aluminum cooling. This pre-mix is good for
temperatures down to -62°F (-52°C). Replace coolant every 2
years or if contaminated.
Cooling System Bleeding
1.Allow the cooling system to cool completely.
2.Check the coolant reservoir and make sure it is at the FULL
COLD mark.
3.Place the snowmobile in its normal riding position and
apply the parking brake and run the engine at the specified
idle RPM until the thermostat opens up.
4.Elevate the front of the machine slightly.
5.Open the bleed screw (A) at the top of the water outlet
manifold.Only open slightly, do not remove the screw.

3
Piston rings are installed with marking or beveled side up see
diagram above.
Coolant Level
Coolant level in the coolant bottle must be maintained to prevent
overheating and serious engine damage. Check the coolant with
the engine temperature cold. The coolant level should be at the
FULL COLD level mark. If it is not add coolant to the FULL
COLD mark on the bottle. If you have coolant over the FULL
COLD level you may have air in the system and need to “bleed”
the air out of the system.

500/600/700 Liberty
6.Cycle the RPM from idle to 3000-4000 so that the coolant
can move around the system and push out the air from the
system.
7.Tighten the bleed screw when coolant starts to come out of
the screw area.
8.Turn off the machine and release the parking brake.
9.Allow the system to cool completely and recheck the
coolant level.
NOTE: It is important that the thermostat stays open
@ 120° F (50° C).When the thermostat opens it will
draw in cold coolant from the heat exchangers and
the cold coolant may close the thermostat again.
3.7
MAINTENANCE
Make sure the thermostat opens and stays open!
Cycle the RPM from idle to enough RPM (3500) to
get coolant to flow but not enough RPM to engage
the clutch. This allows air to bleed from the rear
crossover tube. It is important to get enough coolant
flow to purge the air from the front close-off cooler
and observe this air reaching the bottle.
NOTE: Once the thermostat is open tip the
snowmobile slightly on its right side and cycle the
RPM from idle to enough RPM (4000) to get coolant
to flow but not enough RPM to engage the clutch.
Then tilt the machine slightly on its left side so that
the coolant bottle is the highest point in the cooling
system and cycle the RPM from idle to enough RPM
(4000) to get coolant to flow but not enough RPM to
engage the clutch.
WARN IN G
When performing the following checks and
adjustments, stay clear of all moving parts to avoid
serious personal injury. Never remove the pressure
cap when the engine is warm or hot. If the pressure
cap is to be removed, the engine must be cool.
Severe personal injury could result from stream or hot
liquid.
or tight. Normal hand installation will be an indication of the
recommended interference fit. If the bearing falls out of the case
when the case is inverted, or if the crankcase bearing surface is
severely galled or damaged, the case should be replaced.
NOTE: Crankcase bearing interference fit is .001.002" (.026-.051mm).
Clean crankshaft thoroughly and oil main and connecting rod
bearings with Polaris engine oil. Carefully check each main
bearing on the shaft.
Due to extremely close tolerances, the bearings must be
inspected visually, and by feel. Look for signs of discoloration,
scoring or galling. Turn the outer race of each bearing. The
bearings should turn smoothly and quietly. The inner race of
each bearing should fit tightly on the crankshaft. The outer race
should be firm with minimal side to side movement and no
detectable up and down movement. Replace any loose or rough
bearings.
Bearing Fit
Any time crankshaft bearing failure occurs and the case is to be
reused, Polaris recommends checking the bearing fit into the
case halves using the following procedure.
With case halves cleaned, press a replacement bearing into each
of the main bearing journals to determine a basic amount of
press fit.
Do a comparison check of all journals by manually forcing the
bearing into the bearing seats noting if any are noticeably loose
Connecting Rod (Big End) Bearing
Specialized equipment and a sound knowledge of crankshaft
repair and straightening is required to perform crankshaft work
safely and correctly. Crankshaft repair should be performed by
trained Polaris service technicians in a properly equipped shop.
3.8
MAINTENANCE
Measure connecting rod big end side clearance with a feeler
gauge. 500/600/700 Liberty™ engines should have a clearance
of .011 - .030" (.28 -.75mm) and be equal on all rods within .002"
(.05mm).
= In. / mm.
500/600/700 Liberty Engine Connecting Rod (Big
End) Side Clearance: .011-.030" (.28-.75mm)
Rotate the connecting rod on the crankshaft and feel for any
rough spots. Check radial end play in rod by supporting rod
against one thrust washer and alternately applying up and down
pressure. Replace bearing, pin, and thrust washers if side
clearance is excessive or if there is any up and down movement
detectable in the big end bearing.
6.With pin and bearing centered in rod, twist ends back and
forth in all directions to check for excessive axial play.
7.Pull up and down evenly on both ends of pin to check for
radial play.
8.Replace pin and bearing if there is any resistance to rotation
or excessive axial or radial movement. If play or roughness
is evident with a new pin and bearing, replace the
connecting rod.

CAU TION
Disconnect the battery ground cable and ALL spark
plug high tension leads. Ground high tension leads to
the engine. Disconnect lanyard (if equipped) and/or
press the engine stop switch before proceeding with
the following procedure.
Polaris uses crankshafts that are pressed together. The
connecting rod journal center lines are indexed 180° apart from
each other.
It is sometimes necessary to check multi-cylinder crankshafts to
verify that one cylinder has not been forced out of position
relative to the other cylinder. Some causes for a “out of index”
crankshaft include but are not limited to the following:
Wrist Pin Bearing
1.Clean the end of the connecting rod and inspect inner bore
with a magnifying glass. Look for any surface
irregularities including pitting, wear, or dents.
NEEDLE BEARING
2.Run you fingernail around the inside of the rod and check
for rough spots, galling, or wear.
3.Oil and install needle bearing and pin in connecting rod.
4.Rotate pin slowly and check for rough spots or any
resistance to movement.
5.Slide pin back and forth through bearing while rotating and
check for rough spots.
• Hydrolock from water or fuel
• Impact to drive clutch from object or accident
• Abrupt piston or other mechanical failure
• Engine lock-up due to drive belt failure
Checking Crankshaft Index
1.Remove the drive belt. See “Drive Belt Removal” on
page 6.10.
2.Remove the drive clutch. See “Drive Clutch Removal” on
page 6.15.
3.Securely fasten a large degree wheel on the flywheel or
PTO end of the crankshaft. Make sure that it is mounted
concentrically with the crankshaft center line.
4.With a section of wire (wire coat hanger), anchor it to a
convenient spot. Bend one end at the outer perimeter of the
degree wheel as shown below.
5.Install a dial indicator into the magneto end cylinder spark
plug hole. The ignition timing is referenced by the magneto
end.
6.Locate TDC as accurately as possible by finding the center
of the point where there is no piston movement note the
“Zero” the dial indicator at this point.
3.9
MAINTENANCE
7.Continue to rotate the crankshaft in the normal direction of rotation until the dial indicator reads .100" (2.54mm) after top dead
center (ATDC).
8.Bend the pointer or move the degree wheel until the pointer aligns with a 180° mark on the degree wheel.
9.With the pointer aligned, make sure the degree wheel and pointer are secured and will not move out of position. Re-check
accuracy of this location a few times. The pointer should align with the 180° mark when the dial indicator reads .100” (2.54mm)
ATDC.
NOTE: Do not move the crankshaft, degree wheel or pointer after the initial setting on the MAG end cylinder simply read the wheel and dial indicator.
10. Remove the dial indicator and install in PTO cylinder. Repeat finding TDC. Note the degree wheel indication when the dial
indicator reads .100" ATDC. It should be 180° (+/-2°) from the MAG cylinder mark.
Symptoms of an out of index crankshaft can include but are not limited to the following:
• Difficulty calibrating carburetor (repetitive plug fouling on one cylinder with no other cause)
• Unexplained piston failure on one cylinder (i.e. severe detonation, broken ring lands, piston holing)
• Excessive vibration of engine, back firing, etc.
• Rough idle, poor top speed.

MAINTENANCE
Crankshaft Trueing
Lubricate the bearings and clamp the crankshaft securely in the holding fixture.If trueing the crankshaft requires striking with a
hammer, always be sure to re-check previously straightened areas to verify trueing. Refer to the illustrations below. Use Crankshaft
alignment kit PN 2870569.
NOTE: The Rod Pin position in relation to the dial indicator tells you what action is required to straighten the
shaft.
Truing Examples
To correct a situation like this. Strike the shaft at point A
with a brass hammer.
3
To correct a situation like the one shown in this. Squeeze
the crankshaft at point A. You will use the tool from the
alignment kit PN 2870569.
If the crank rod pin location is 180° from the dial
indicator (opposite of above), it will be necessary to
spread the crankshaft at the A position as shown in
illustration 3. When rebuilding and straightening a
crankshaft, straightness is of utmost importance. Runout
must be as close to zero as possible.

1.To aid in bleeding the air out of the oil lines, fill oil
reservoir with the appropriate Polaris injector oil. This will
add pressure to the oil lines.
2.Loosen the bleed screw (A). After approximately 30
seconds oil should flow from beneath the screw head. This
will indicate the pump is free of the air.
3.Tighten bleed screw (A) securely.
NOTE: Any time that the engine is disassembled or
repaired, it is important that the oil supply from the
oil pump be checked and full of oil.
IMPORTANT: The oil pump must always be bled
following any service to the oil injection system or
engine.
Oil / Fuel Filter

NOTE: Acceptable crankshaft runout (in a crank
fixture) is 0 - .0015" (0 - .04mm) on Liberty™
engines. 0 - .0025" (0 - .07mm) on Fuji engines.
CAU TION
The in tank fuel filter and fuel lines should be inspected
regularly. Special attention should be given to the fuel
line condition after periods of Summer storage. Normal
deterioration from weather and fuel can occur during this
storage period. Do not damage fuel lines when removing
them. If a fuel line has been damaged or kinked it must
be replaced.
NOTE: The direction of the arrow indicates the
direction of the flow through the filter. After
changing the oil filter, the oil injection system must
be bled of all trapped air. see “Oil Pump Bleeding”
on page 3.12.
3.12
MAINTENANCE
Most models use an oil and fuel filters which are of a special
design and must not be substituted. These filters should be
changed and the oil and fuel lines should be inspected annually
or every 1000 miles (1600 km).
These filters may have an arrow on the filter or line. This arrow
is the direction of flow. Install accordingly.
EDGE models utilize a special oil filter that is built into the oil
sending unit located in the bottom of the oil tank. It should be
replaced every two years or 2400 miles (3862 km).
CFI models fuel filter should be replaced every 1000 miles
(1600km).

Fluid Replacement & Bleeding” on page 7.20.
Brake Fluid
WARN IN G
Do not over fill the master cylinder. Fluid expansion
could cause brakes to lock, resulting in serious injury or
death. Once a bottle of brake fluid is opened, use what
is necessary and discard the rest. Do not store or use
a partial bottle of brake fluid. Brake fluid is hygroscopic,
meaning it rapidly absorbs moisture from the air. This
causes the boiling temperature of the brake fluid to
drop, leading to early brake fade and the possibility of
serious injury
Inspect the reservoir to be sure it contains the correct amount of
fluid. Use only Polaris DOT 4 high temperature brake fluid.
Change fluid every 2 years or whenever the fluid is dark or
contamination is suspected.

Belt Deflection Inspection
Belt deflection is critical for optimum belt performance and belt
life. It should be checked at 500 miles (800km) and then in 1000
mile (1600km) increments after that.
Too much belt deflection is when the belt is too long or the center
distance is too short. The initial starting ratio will be too high,
resulting in performance loss. This is due to the belt rising too
high in the drive clutch sheaves upon engagement (A).
Not enough belt deflection (B) is when the belt is too short or the
center distance is too long. The initial starting ratio will be too
low. In addition, the machine may creep when the engine idles,
causing damage to the internal face of the drive belt.
Measuring Belt Deflection
1.Measure the belt deflection with both clutches at rest and
in their full neutral position.
2.Place a straight edge across the tow clutches, on top the belt.
3.Apply downward pressure to the belt and measure the
distance at point (D).
4.The measurement should be 1 1/4" (3.2cm).
= In. / mm.
Belt Deflection: 1.25" (3.2cm)

and the coolant is under pressure may cause
serious scalding.
One method of draining coolant from an engine is to use low air
pressure to aid the extraction of coolant.
1.Remove pressure cap.
2.Siphon as much coolant as you can from the coolant bottle
and coolant lines.
3.Remove the top hose from the thermostat and insert it into
an empty container.
4.Apply 3-5 psi of air pressure to the thermostat cover until
no more coolant can come out of the thermostat hose that
you inserted into the container.
NOTE: This will only get the majority of the coolant
out. Some may remain in the system.
When servicing the carburetor or fuel
system, it is important to heed the following
warnings.
WARN IN G
Always stop the engine and refuel outdoors or in a well
ventilated area
WARN IN G
Do not smoke or allow open flames or sparks in or near
the area where refueling is performed or where
gasoline is stored or used.
WARN IN G
Do not overfill the tank. Do not fill the tank neck.
thoroughly familiarizing him/herself with procedures before
beginning. Photographs and illustrations have been included
with the text as an aid. Notes, cautions and warnings have also
been included for clarification of text and safety concerns.
However, a knowledge of mechanical theory, tool use and shop
procedures is necessary to perform the service work safely and
satisfactorily. Use only genuine Polaris service parts.
Cleanliness of parts and tools as well as the work area is of
primary importance. Dirt and foreign matter will act as an
abrasive and cause damage to precision parts. Clean the
snowmobile before beginning service. Clean new parts before
installing.
Watch for sharp edges which can cause personal injury,
particularly in the area of the tunnel. Protect hands with gloves
when working with sharp components.
If difficulty is encountered in removing or installing a
component, look to see if a cause for the difficulty can be found.
If it is necessary to tap the part into place, use a soft face hammer
and tap lightly.
Some of the fasteners in the snowmobile were installed with
locking agents. Use of impact drivers or wrenches will help
avoid damage to fasteners.

WARN IN G
If you get gasoline in your eyes or if you swallow
gasoline, see your doctor immediately.
WARN IN G
If you spill gasoline on your skin or clothing,
immediately wash it off with soap and water and
change clothing.
WARN IN G
Never start the engine or let it run in an enclosed area.
Gasoline powered engine exhaust fumes are
poisonous and can cause loss of consciousness and
death in a short time.
GENERAL INFORMATION
Service Precautions
In order to perform service work efficiently and to prevent
costly errors, the technician should read the text in this manual,
Always follow torque specifications as outlined throughout this
manual. Incorrect torquing may lead to serious machine damage
or, as in the case of steering components, can result in injury or
death for the rider(s).
If a torquing sequence is indicated for nuts, bolts or screws, start
all fasteners in their holes and hand tighten. Then, following the
method and sequence indicated in this manual. Tighten evenly
to the specified torque value. When removing nuts, bolts or
screws from a part with several fasteners, loosen them all about
1/4 turn before removing them.
If the condition of any gasket or O-Ring is in question, replace
it with a new one. Be sure the mating surfaces around the gasket
are clean and smooth in order to avoid leaks.
Some procedures will require removal of retaining rings or
clips. Because removal weakens and deforms these parts, they
should always be replaced with new parts. When installing new
retaining rings and clips use care not to expand or compress
them beyond what is required for installation.
Because removal damages seals, replace any oil or grease seals
removed with new parts.
Polaris recommends the use of Polaris lubricants and greases,
which have been specially formulated for the top performance
and best protection of our machines. In some applications, such

as the engine, warranty coverage may become void if other
brands are substituted.
Grease should be cleaned from parts and fresh grease applied
before reassembly of components. Deteriorating grease loses
lubricity and may contain abrasive foreign matter.
Whenever removing or reinstalling batteries, care should be
taken to avoid the possibility of explosion resulting in serious
burns. Always disconnect the negative (black) cable first and
reconnect it last. Battery electrolyte contains sulfuric acid and
is poisonous! Serious burns can result from contact with the
skin, eyes or clothing. ANTIDOTE: External - Flush with
water. Internal - Drink large quantities or water or milk. Follow
with milk of magnesia, beaten egg, or vegetable oil. Call
physician immediately. Eyes - Flush with water for 15 minutes
and get prompt medical attention.
FUEL DELIVERY SYSTEM
(CARBURETED)
Carbureted System Overview
The carbureted fuel system contains many components which
directly affect fuel mixture and performance. When performing
diagnosis or carburetor maintenance, the entire fuel delivery
system should be inspected.
Fuel filters should be replaced at least once per season. More
often if contamination is suspected.
Fuel lines should be replaced every other season. More often if
they become brittle or swollen. Fittings should be inspected for
cracks or leaks. Do not use pliers or other tools that may damage
fuel lines when installing or removing fuel lines.
Test run and check the fuel system for leaks any time parts are
replaced. Verify that all lines are routed correctly and away from
any moving parts.
NOTE: Some models use fuel filters that are located
inside the fuel tank. To inspect/replace filter, remove
fuel cap and use a long clean wire, bend one end
into a hook shape. Pull the fuel line that is in the
tank up through the filler hole. Inspect filter on end
of fuel pick up line. Replace if worn or clogged.
When replacing fuel line, be sure to use the correct color line for
inside or outside the fuel tank. Also, be very careful not to bend
fuel line to a point of kinking it. If it becomes kinked, it must be
replaced. Always inspect fuel lines when replacing, or if carbs,
carburetor racks, or fuel pumps are removed from chassis.
FUEL PUMP (CARBURETED UNITS)
Fuel Pump Overview
The differences are in the size and
location of the pumps. Pumps may
be mounted to the engine, air/oil box
or to the chassis.
In the two cycle engine, the pressure
in the crankcase changes with the up
and down stroke of the piston. The
amplitudes of pressure vary
according to the RPM and degree of
throttle opening. Whether idling or at
full throttle, the pressure built up in
the crankcase has enough amplitude
to operate the pump.
When the piston is on the upstroke,
crankcase pressure in that cylinder
becomes less positive. The
diaphragm in the fuel pump moves
toward the engine, causing a
negative pressure or suction in the
pump chamber. This causes the inlet
valve from the fuel supply to open
and permits fuel to enter the chamber. This same suction causes
the outlet valve (to the carburetor) to close so that fuel cannot
return to the carburetor. (340/550 style shown)
When the piston begins its downward stroke, the pressure from
the crankcase becomes positive, causing the fuel pump
diaphragm to move in the opposite direction and reversing the
pressure in the fuel pump chamber. This causes the inlet valve
in the pump to close and the outlet valve to open, filling the float
bowl in the carburetor. When the float level in the carburetor
reaches its standard level, the needle valve will close,
preventing more fuel from entering the carburetor, even though
the fuel pump continues to try to provide the carburetor with
fuel.
Red fuel line is the exterior line for outside the tank. The violet
line is the interior line for inside the fuel tank. They cannot be
interchanged! The violet line used inside the tank will fade and
turn clear after a relatively short time. This does not affect the
function or durability of the line.
4.4
FUEL DELIVERY
Maintenance
The impulse operated diaphragm fuel pump does not require any
specific scheduled maintenance. However, the following
procedures should be observed:
• Operation
The pump may be checked for operation by removing the fuel
supply line from the carburetor and placing it into a container.
With the engine idling at approximately 2000 RPM, a steady
flow of fuel should be visible.
• Cleaning
The pump and impulse line must be disassembled and cleaned
of foreign material in the event of piston or other internal engine
part failures which produce fragments.
• Inspection
Disconnect impulse line from pump. Connect a Mity Vac to
impulse fitting (or line) and apply 4-6 PSI pressure. Diaphragm
should hold pressure indefinitely.
The diaphragms and check valves must be carefully examined
for cracks, holes, or other damage. If in doubt as to the condition
of any internal parts, replace all diaphragms, check valves, and
gaskets.

MIKUNI JET NEEDLE
Overview
This needle (example) is a 9DH01-57. The first number is the
approximate overall length in 10mm increments of the jet
needle. The 9 indicates the needle is approximately 90mm but
less that 100mm in length.
The letters on the jet needle indicate the angle of both tapers. The
first letter designates the taper angle of the top section (closest
to the grooves) and the second letter designates the angle of the
bottom taper. The taper angles are graduated in 15' (15 minute)
increments. The jet needle marked 9DH01-57 would have a top
taper of 1_0' and a bottom taper of 2_0'.
The number following the letters on the jet needle is the serial
number and it varies with individual jet needles.
The last number, 57 indicates that the outside diameter is
2.57mm. The smaller the O.D., the richer the mixture.

MIKUNI TM 38
Carburetor Overview
The advantages of the TM flatslide system include improved
throttle response and a significant reduction in throttle effort
due to rack style carbs and the use of cable cam. The following
are the main components of TM carburetors and the functions
of each components.
Pilot Air Jet (A): The pilot air jet controls the amount of air
entering the engine in the idle circuit. The pilot air jet size is
imprinted on it. Bigger pilot air jets allow more air to enter,
leaning the idle mixture. If engine loads up at idle, first try
turning fuel screw in. If not correct, try larger pilot air jet.
Starter Jet (B): The starter jet's function is to meter fuel
entering the engine when choked. Larger numbered starter jets
pass more fuel, therefore more fuel will enter the system when
jetting to a larger size. Like the pilot air jet, the jet size is
imprinted.
Jet Needle (C): The jet needle performs the same functions as
on Mikuni VM carburetors. However, the needles in the TM-38
carburetors are longer and are not interchangeable with VM
needles. To raise or lower the needle, remove the top cap (D)
and loosen the 2.5mm Allen screw holding the needle in place.
Reach inside with a long nose pliers and pull the needle out. The
C-clip can then be adjusted for the desired effect.
Needle Jet (D): The needle jet is press fit into carbs and is not
replaceable.
P is to n Va lv e o r T hr ot tl e Va lv e ): The throttle valve controls the
rate of engine air intake by moving up and down inside the main
bore. At small throttle openings, air flow control is performed
chiefly by the cutaway. By controlling air flow the negative
pressure over the needle valve is regulated, in turn varying the
fuel flow
Main Jet and Pilot Jet (F): The main jets (hex) and pilot jets
(air bleed type) are identical in style and function as the Mikuni
VM carbs. There is a washer on a main jet that is staked and
should not come out. The part numbers for main jets and pilot
jets are the same as Mikuni VM round slide carburetors.
Fuel Screw (G): The fuel screw controls the low speed air/fuel
mixture at idle. Turning the fuel screw out makes the mixture
richer and can be adjusted up to three turns out.
4.6
FUEL DELIVERY
Float/Needle & Seat Assembly (H): The float/needle & seat are
sold as an assembly and cannot be replaced as individual
components. The float level is pre-set in the molding and cannot
be adjusted.
WARN IN G
DO NOT pressurize the fuel system by forcing compressed
air through the fuel tank. Forcing air through the needle and
seat will cause damage and the float/needle & seat assembly
will have to be replaced.
Carburetor Synchronization: Remove the top caps on all
carburetors. In the body of the carburetors, there is a Phillips
head set screw (I) that connects the slide lever to the throttle
lever shaft. The carburetor with the fixed set screw is the base
carburetor (middle carburetor on triples, PTO carburetor on
twins) and the remaining carbs are synchronized to it.
Carburetor synchronization is measured at wide open throttle.
Open the throttle to wide open. The bottom of the slide should
be flush with the top of the throttle bore. If it is not flush, locate
the wide open throttle stop screw (J) and turn it until the base
carburetor is set flush. Loosen the Phillips head set screw in the
remaining carburetor(s). Turn the adjusting nut (K) that
surrounds the set screw until the throttle slide is set the same as
the base carburetor. Tighten all set screws and replace the top
caps making sure gaskets are properly positioned.
MIKUNI CARBURETOR
4
Function
The function of a carburetor is to produce a combustible air/fuel
mixture by breaking fuel into tiny particles in the form of vapor,
to mix the fuel with air in a proper ratio, and to deliver the
mixture to the engine. A proper ratio means an ideal air/fuel
mixture which can burn without leaving an excess of fuel or air.
Whether the proper mixture ratio is maintained or not is the key
to efficient engine operation.
The engine of a vehicle is operated under a wide range of
conditions, from idling with the throttle valve remaining almost
closed, to full load or maximum output with the throttle valve
fully opened. In order to meet the requirements for the proper
mixture ratio under these varying conditions, a low speed fuel
system, or pilot system, and a main fuel system are provided in
Mikuni type carburetors. The Mikuni carburetor has varying
operations depending upon varying driving conditions. It is
constructed of a float system, pilot system, main system, and
starter system or initial starting device.
4.7
FUEL DELIVERY
Float System
The float system is designed to maintain a constant height of
gasoline during operation. When the fuel flowing from the fuel
pump into the float chamber through the needle valve reaches
the constant fuel level, the floats rise. When the buoyancy of the
float and the fuel pressure of the fuel pump balance, the needle
valve sticks fast to the needle seat, preventing further delivery
of gasoline, thereby holding the standard level of gasoline.
The fuel level in the bowl assists in controlling the amount of
fuel in the fuel mixture. Too high a level allows more fuel than
necessary to leave the nozzle, enriching the mixture. Too low a
level results in a leaner mixture, since not enough fuel leaves the
nozzle. Therefore, the predetermined fuel level should not be
changed arbitrarily.
Fuel Metering
Fuel Delivery
The pilot system's
main function is to
meter fuel at idle
and low speed
driving. Though its
main function is to
supply fuel at low
speed, it does feed
fuel continuously
throughout the
entire operating
range.
Fuel for the pilot
jet is drawn from
the float bowl,
mixed with air jet,
and delivered to
the engine through the pilot outlet.
The mixture is regulated to some degree by adjusting the fuel
screw.
The main system is designed to deliver fuel between low speed
and high speed operation. This system is made up of the jet
needle, needle jet, and main jet. The main system begins to take
effect as soon as there is enough air flow into the carburetor
venturi to draw fuel up through the main jet and needle jet
assembly. This system works in conjunction with the needle jet
system.
FUEL METERING
Mikuni carburetors use a starter enricher system rather than a
choke. In this type of carburetor, fuel and air for starting the
engine are metered with entirely independent jets. The fuel
metered in the starter jet is mixed with air and is broken into tiny
particles in the emulsion tube. The mixture then flows into the
plunger area, mixes again with air coming from the air intake
port for starting and is delivered to the engine through the fuel
discharge nozzle in the optimum air/fuel ratio. The starter is
opened and closed by means of the starter plunger. The starter
type carburetor is constructed to utilize the negative pressure of
the inlet pipe, so it is important that the throttle valve is closed
when starting the engine
4.8
During low speed driving, there is very little clearance between
the jet needle and the needle jet; therefore, very little fuel from
the main jet can pass between the jet needle and the needle jet.
As the throttle valve opening is increased, the tapered jet needle
is raised farther out of the needle jet, allowing greater fuel flow.
Under full throttle opening, the cross sectioned area of
clearance between the jet needle and the needle jet becomes
greater than the cross sectioned area of the main jet. Thus the
main jet is now controlling the amount of fuel flow.
Pilot Jet
From idling to low speeds, the fuel supply is metered by the pilot
jet. There are several air bleed openings in the sides of the pilot
jet which reduce the fuel to mist. The number stamped on the jet
is an indication of the amount of fuel in cc's which passes
through the jet during a one minute interval under a given set of
conditions.
FUEL DELIVERY
Fuel Screw
The fuel screw controls the fuel mixture from idle to low speeds.
The tapered tip of the fuel screw projects into the passage
leading to the by pass out let. By turning the screw in or out, the
cross sectional area of the air passage is varied, in turn varying
the fuel screw varies the amount of air/fuel.
Main Jet
When the throttle
opening becomes
greater and the area
between the needle jet
and jet needle increases,
fuel flow is metered by
the main jet. The number
on the jet indicates the amount of fuel which will pass through
it in one minute under controlled conditions. Larger numbers
give a greater flow, resulting in a richer mixture. Main jets are
screwed directly into the needle jet base.
Jetting Guidelines
Changes in altitude and temperature affect air density, which is
essentially the amount of oxygen available for combustion. In
low elevations and cold temperatures, the air has more oxygen.
In higher elevations and higher temperatures, the air is less
dense.
always use the lowest elevation and temperature
that is likely to be encountered.
CAU TION
A Main Jet that is too small will cause a lean operation
condition and may cause serious engine damage. Jet
the carburetors carefully for elevation and temperature
according to the jetting charts in the, Specifications
Chapter of this manual or the models Owner’s Manual
Supplements.
Piston Valve Or Throttle Valve
4
Verify the production setting for your specific model. All
carburetors must be re-calibrated if operated outside the
production temperature and/or altitude range. The main jet
installed in production is not correct for all altitudes and/or
temperatures. Refer to the jetting cart in the Specifications
Chapter of this manual for correct jetting for altitude/
temperature ranges.
NOTE: It is the owner's responsibility to ensure that
the correct jets are installed in the machine for a
geographical area. Be very careful when jetting
down in warm weather. As the weather turns colder
it will be necessary to re-jet upward to prevent
engine damage. When selecting the proper main jet
intake side
The throttle valve controls the rate of engine air intake by
moving up and down inside the main bore. At small throttle
openings, air flow control is performed chiefly by the cutaway.
By controlling air flow the negative pressure over the needle
valve is regulated, in turn varying the fuel flow.
The throttle valves are numbered 1.0, 1.5, 2.0, etc., according to
the size of the cutaway in millimeters. The higher the number,
the leaner the gasoline/air mixture.
4.9
FUEL DELIVERY
Jet Needle / Needle Jet
The jet needle and needle jet have the most effect between 3/8
and 3/4 throttle opening. Some mixture adjustment can be
accomplished by changing the location of the “E” clip on the
needle. Moving the clip down raises the needle in the jet passage
and enriches the mixture. Moving the clip up lowers the needle
in the jet passage and leans the mixture. Letter and number
codes are stamped into the needle and the jet indicating sizes
and tapers (taper of needles only) of each.
Jet Needle
The jet needle tapers off at one end and the clearance between
the jet needle and the needle jet increases as the throttle valve
opening gets wider. The air/fuel mixture ratio is controlled by
the height of the “E” ring inserted into one of the five slots
provided in the head of the jet needle.
Needle Jet
The needle jet works in conjunction with the jet needle.

CLEANFIRE INJECTION (CFI)
Injector Replacement
The Cleanfire system utilizes 3 different color injectors. If you
are replacing an injector you must replace it with the same color
injector you remove.
The color is indicated in three ways, 1) it will be on the short wire
harness that is attached to the injector, 2) the injector will have
a colored dot on the shaft of the injector 3)it is indicated on the
label of the ECU.
If the color injector is not available you may replace all injectors
with a different color and you must program the ECU to run the
new installed color.

NOTE: If the injector is on the upper fuel rail, only
the air box needs to be removed to gain access to
the failed injector.
NOTE: If the injector is on the lower fuel rail, engine
removal is necessary for injector access. See “600 /
700 HO CFI ENGINE” on page 5.29.
NOTE: When installing replacement injector(s) keep
the red protective cap on the end of the injector to
prevent damage when installed. Follow the steps
and remove when instructed to do so.
1.Depressurize the fuel rail. See “Fuel Rail Bleeding” on
page 4.20.
2.Remove the panduit straps (1-4) as shown.

If it is verified that an injector needs to be replaced, you must
first find out what injector color is on the unit. You can do this
by checking the decal that is located on the top portion of the
ECU or by the color band that is next to the injector on the
harness.
1.Bleed the fuel rail. See “Fuel Rail Bleeding” on page 4.20.
2.Remove the seat and fuel tank. See “IQ Fuel Tank
Removal” on page 10.6.

panduit straps back to the original locations, making sure
they are not applied over any mesh part of the fuel rail.
NOTE: Refer to Step 2 for proper routing and strap
location.
14. Install the engine if it was removed. See “600 / 700 HO CFI
ENGINE” on page 5.29.

Cleanfire System Overview
B
A
D
C
700 CFI
The Cleanfire fuel system uses a fuel pump (A) that is located
inside the fuel tank, a fuel rail (C) with in-line fuel filter (B), and
injectors (D). The fuel pump will create a pressure in the system
and deliver the fuel mixture to the injectors. The injectors get a
signal from the engine controller unit (ECU) and sprays into the
engine.
The only maintenance that is needed with this system is that the
fuel filter (B) needs to be changed every 1,000 miles (1600km).
Fittings should be inspected for cracks or leaks. Do not use pliers
or other tools that may damage fuel lines when installing or
removing fuel rail.
Fuel Pump (700)
4
This fuel pump on this system is non-serviceable and can not be
replaced. If fuel pump fails, the whole fuel tank assembly must
be replaced.
FUEL PUMP: Located inside tank. It provides system with fuel
at 58psi (4bar) pressure. If the fuel pressure is suspect to be
defective apply 12 VDC to the fuel pump prime (Red (#1) and
the Brown (#3) wires) and check for audible fuel pump
operation as well as fuel rail pressure. The fuel pump should
sound when pumping and the pressure should show 58psi (4 bar)
pressure.
Fuel travels from the fuel pump through the fuel filter and to the
injectors. Any fuel that is not delivered through the injectors will
travel back to the fuel tank through the return line.

Fuel Rail Bleeding
The 2007 600 CFI units will have one of two different styles of
Schrader valves.
A shallow core valve (1) and will use the adapter that comes with
the fuel pressure gauge (PN PV-43506-A).
A deep core valve (2) will need the adapter PN PS-48167.
1
The fuel pressure gauge (PN PV-43506-A) is used to check or
bleed the pressure in the fuel rail lines. You will need to bleed
off the fuel pressure if any service is needed to the fuel system
or if engine is to be removed.
1.Select the appropriate adapter for your valve type.
• Adapter (3) is used on the shallow core valve.
2
• Adapter (4) is used on the deep core valve.

2.Attach the correct gauge to the valve on the fuel pressure
tool.
3.Once the gauge is onto the Schrader valve, the pressure
gauge will indicate the pressure in the fuel rail.
4.To bleed the pressure from the fuel rail, you can turn the
bleeder valve on the gauge and bleed the system safely.
5.At this point the fuel rail is ready for service.
