GENERAL
PISTON WASH / SPARK PLUG READING
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.
GASOLINE INFORMATION
GASOLINE VOLATILITY
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
2.9
GENERAL
pump, or carburetor. This will cause warm engine drive ability
problems and hard starting when warm. Some states are
limiting the Reid Vapor number to 9.0 PSI year around to help
meet evaporative emissions standards.

2 STROKE GASOLINE / OIL PRE MIX
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.
1 gallon has 128oz. / 20 = 6.4 oz. of oil needed to mix to each
1 gallon of gasoline. For a 5 gallon mixture, you would need
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.
Replace cylinder head if measurement exceeds the service
limit of .003" (.08mm).
NOTE: Cylinder head warp service limit is:
.003”(.08mm).

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 1/2” from the top of the cylinder; in line with the

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.

HONING PROCEDURE
1. Wash the cylinder with solvent.
2. Clamp the cylinder in a soft jawed vise by the exhaust port
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 1/2" (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 1/2" (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 (340/550/500 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.
(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 Libertyt engines,
measure piston outside diameter at a point 3/8" (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 1/2" (12.7mm) up form the bottom
of the skirt at a 90_ angle to the direction of the piston pin.
90qto 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 oversizing 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.
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
DOMESTIC ENGINES - Measure 3/8s(10.0mm)
up from bottom of skirt
FUJI ENGINES - Measure 1/2s(12.7mm) up
from bottom of skirt
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.

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. Open the bleed screw (A) at the top of the water outlet
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.

WARNI N 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

5. 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.
6. Tighten the bleed screw when coolant starts to come out of
the screw area.
7. Turn off the machine and release the parking brake.
8. Allow the system to cool completely and recheck the
coolant level.
NOTE: It is important that the thermostat stays
open! When the thermostat opens it will draw in cold
coolant from the heat exchangers and the cold
coolant may close the thermostat again. Make sure
the thermostat opens and stays open! Cycle the
RPM from idle to enough RPM (4000) 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.
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 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).

MAINTENANCE
MAIN BEARING
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.
CONNECTING ROD (BIG END) BEARING
Within .002” (.05mm)
side clearance is excessive or if there is any up and down
movement detectable in the big end bearing.
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.
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.
Measure connecting rod big end side clearance with a feeler
gauge. 500/600 Libertyt engines should have a clearance of
.011 - .030" (.28 -.75mm) and 700/800/900 Libertyt
engines should have .011 - .028" (.28 - .70mm) and be equal
on all rods within .002" (.05mm).
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
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.
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 following procedure.
Polaris uses crankshafts that are pressed together. The
connecting rod journal center lines are indexed 180_(twins).
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 ar not limited to the following:
• Hydraulock 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
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. Recheck 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:
• 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.
CRANKSHAFT TRUING
Lubricate the bearings and clamp the crankshaft securely in
the holding fixture.If truing the crankshaft requires striking
with a hammer, always be sure to re-check previously
straightened areas to verify truing. Refer to the illustrations
below. Use Crankshaft alignment kit PN 2870569.
CHECKING CRANKSHAFT INDEX
1. Remove the drive belt, see DRIVE BELT in Chapter 7.
2. Remove the drive clutch, see “DRIVE CLUTCH
REMOVAL” on page 7.10.
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 above.
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.
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).

OIL / FUEL FILTER
CAU T ION
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 3.13.
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.
BRAKE LEVER TRAVEL
The brake lever travel should have a clearance no less than 1/
2” (1.27cm) from the handlebar grip. Inspection should be
made with the lever firmly depressed. If the lever has less than
this amount you may need to bleed the brake system, see
“BRAKE FLUID REPLACEMENT & BLEEDING” on
page 8.3.
BRAKE FLUID
WARNI N 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
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).
700/900 FUSION/RMK models use the in-line filter and
should be replaced every two years or 2400 miles (3862 km).

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

NOTE: Track alignment affects track tension.
Misalignment of the track will cause excessive wear
to the track, rail slides, and rail.
NOTE: Excessive rail slide wear occurs due to
running in inadequate snow conditions.
Periodically check that the track is centered and running
evenly on the slide rails. Misalignment will cause excessive
wear to the track and slide rails.
1. Safely lift and support the rear of the snowmobile off the
ground.
2. Rotate the track by hand to check for any possible damage.
3. Inspect the track rods (A) carefully and examine the track
along the entire length of each rod, bending the track edge
and inspecting it for breakage. If any rod damage is found,
the track should be replaced.
4. Warm up the track by starting the engine and apply a small
amount of throttle so the track runs slowly at least five
complete revolutions.
5. Stop the engine and turn the ignition off.
6. Inspect track alignment by carefully looking through the
track window (B) to make sure the rails (C) are evenly
spaced on each side.
7. Before any adjustments are made loosen up the rear idler
shaft (F).
8. If the track runs to the left, loosen the left locknut and
tighten the left adjusting bolt (D). If the track runs to the
right, loosen the right locknut and tighten the right
adjusting bolt. It may be necessary to check this with the

TRACK LUBRICATION
WARNI N G
Operating with insufficient lubrication between the rail
slide and track guide clips can cause track failure, loss
of vehicle control and loss of braking ability, which can
result in serious injury or death. Avoid operating vehicle
on ice and other surfaces that have little or no snow
conditions.
The slide rail needs snow for lubrication and cooling.
Excessive wear indicates insufficient lubrication. A new rail
slide can cause faster heat build-up in limited lubrication,
resulting in excessive wear.
NOTE: If excessive rail slide wear occurs due to
poor snow conditions additional wheel kits can be
added.

track to slip or “ratchet” on the drive shaft drivers and cause
the track and rear suspension durability problems. If the track
is too tight the track will wear down the rail slides, reduce top

track. This measurement should fall with in the
measurement range for the appropriate vehicle.
6. If adjustment is needed, loosen up the lock nuts (B) on
each side.
7. Loosen up the idler shaft bolts (F).
8. Turn each adjuster bolt (C) toward the idler wheel
(clockwise) if you need less of a measurement. Tun the
adjuster bolt (C) toward the front of the sled
(counterclockwise) if you need a greater measurement.
9. When you achieve the correct tension listed below, torque
the lock nuts (B) and idler shaft bolts on each side to 35 ftlb (48Nm).
NOTE: Track alignment affects track tension.
Misalignment will cause excessive wear to the track
and slide rails. Excessive slide wear will appear on
units with the track tension set too tight (or below
measurement specification).

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.

GENERAL INFORMATION
SERVICE PRECAUTIONS
In order to perform service work efficiently and to prevent
costly errors, the technician should read the text in this
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.

CARBURETION
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 drive ability. When performing
diagnosis or carburetor maintenance, the entire fuel delivery
system should be inspected. The illustration above shows parts
of the system requiring periodic maintenance to ensure there is
no fuel or air leaks present.
Fuel filters should be replaced at least once per season. More
often if any 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 in 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.
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.
4.3
CARBURETION
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 (non-injected units)
4.4
FUEL PUMP OVERVIEW
The fuel pumps (340/550 style shown). 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
CARBURETION
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 form the carburetor.
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.
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.

CARBURETION
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 TM38 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.
Piston Valve or Throttle Valve): 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 washer on 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 five turns out.
Float/Needle & Seat Assembly (H): The float/needle & seat
are sold as an assembly and cannot be replaced as individual
4.6
CARBURETION
components. The float level is pre-set in the molding and
cannot be adjusted.
WARNI N 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.
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.
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.
MIKUNI CARBURETOR
FUNCTION
The function of a carburetor is to produce a combustible air/
fuel mixture by breaking fuel into tiny particles in the form of
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.
4.7
CARBURETION
FUEL METERING
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
FUEL
DELIVERY
The mixture is regulated to some degree by adjusting the air
screw. When the air screw is closed, the fuel mixture is made
richer as the amount of air is reduced. When the air screw is
opened, the mixture is made more lean as the amount of air is
increased.
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.
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.
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 regulated by the air screw, and
delivered to the engine through the pilot outlet.
4.8
PILOT AIR SCREW
The pilot air screw controls the fuel mixture from idle to low
speeds. The tapered tip of the air screw projects into the air
passage leading to the pilot jet air bleeds. By turning the screw
in or out, the cross sectional area of the air passage is varied,
in turn varying the pilot jet air supply and changing the
mixture ratio.
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 cc's
CARBURETION
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.
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
always use the lowest elevation and temperature
that is likely to be encountered.
CAU T ION
PISTON VALVE or THROTTLE VALVE
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.
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 Owners Manual
Supplements
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.
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 richens 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
4.9
CARBURETION
provided in the head of the jet needle. The chart at right shows
the variation of fuel flow based on the height of the “E" ring.
NEEDLE JET
The needle jet works in conjunction with the jet needle to
regulate fuel flow rate. An air bleed opening in the side of the
needle jet brings in air measured by the air jet. This air
initiates the mixing and atomizing process inside the needle
jet. Mixing is augmented by a projection at the needle jet
outlet, called the primary choke. The letter number code
stamped on the jet indicates jet inside diameter.
