Introduction
We would like to congratulate you on your purchase of a KTM motorcycle. Let us also take this opportunity to thank you for putting your trust in us; we will not let you down.
You are now owner of a sporty and modern motorcycle which you are bound to have a great time with provided you care for it properly. Before going for a first ride on your motorbike, you should
read this Owner’s Handbook carefully, even if this takes some of your precious time, so as to familiarize yourself with how your motorbike is to be operated and which features it offers you. Only by doing so will you learn how you can best tune your motorcycle to your needs and how you can avoid bodily injuries. In addition, this Owner’s Handbook contains invaluable informa­tion about motorcycle maintenance. At the time of printing, this User's Guide corresponded to the
latest state of this model family. It is, however, possible that we may have made slight modificati­ons in the meantime due to development in our motorcycle design. The Owner’s Handbook is an essential part of the motorbike and should - when the bike is sold ­be handed over to the new owner.
Many motorcyclists have a good working knowledge of motorcycle mechanics; if this is true in your case, you will be able to use this Owner’s Handbook to carry out most of the maintenance steps yourself. If, on the other hand, you are not very familiar with motorcycles, it might be better to have a professional KTM dealer perform those steps marked by *found in the chapter entitled “Maintenance Work on Chassis and Engine” of this manual.
Take special care to follow the recommended run in, inspection, and maintenance intervals. Heeding these guidelines will significantly increase the life of your motorcycle. Be sure to have any maintenance jobs performed by an authorized KTM dealer. Address your special requests to an authorized KTM dealer who, should the need arise, will be supported by the KTM importer.
Please do not forget to don your helmet, eye protection, and protective clothing when going for a ride. KTM riders are responsible riders! We wish you a lot of fun when driving !

Instructions for initial operation
– Verify that your KTM dealer performed the PREPARATION
OF VEHICLE jobs (see Customer Service Manual).
– Read these operating instructions carefully before your first
ride. – Familiarize yourself with the operating elements. – Set the clutch lever, the handbrake lever, and the footbrake
pedal to the positions that are most convenient for you. – Get used to handling the motorcycle on an empty parking
lot or open space, before starting on a longer drive. Also try
to drive as slowly as possible and in standing position, to
improve your feeling for the vehicle. – Do not drive along off-road tracks which go beyond your
abitily and experience. – Hold the handle bars with both hands and leave your feet
on the foot rests while driving. – Remove your foot from the foot brake lever when you are
not braking. If the foot brake lever is not released the brake
pads rub continuously and the braking system is over-
heated. – Do not make any alterations to the motorcycle and always
use ORIGINAL KTM SPARE PARTS. Spare parts from other
manufacturers can impair the safety of the motorcycle. – Motorcycles are sensitive to alterations in the distribution of
weight. If you are taking luggage with you, this should be
secured as close as possible to the middle of the vehicle; dis-
tribute the weight evenly between the front and rear wheel.
Never exceed the maximum permissible laden weight and
the axle weights. The maximum permissible laden weight is
made up of the following components:
– Motorcycle ready for operation and tank full
– Luggage
– Driver with protective clothing and helmet. – Pay attention to running-in procedure.
Running in the Racing models
Even very precisely machined sections of engine components have rougher surfaces than components which have been sli­ding across one another for quite some time. Therefore, every engine needs to be broken in. For this reason, do not load the engine more than 50% of its capacity during the first 3 operating hours. Besides, the engine speed must not exceed 7000 rpm. Avoid going full-throttle! In the following 12 operating hours, you may load the engine up to 75% of its capacity. Use the motorcycle on various types of terrain (road, easy off-road trails).

HE 400/520 SC/EXC RACING MODELS WERE UNCOMPROMISINGLY
DESIGNED FOR OFF
-ROAD COMPETITION PURPOSES ONLY. EVEN THOUGH
THE

ON ROADS IS RECOMMENDABLE ONLY TO A VERY LIMITED EXTENT
. AVOID
EXTENDED ON
-ROAD RIDES AT FULL THROTTLE.
Check the following before each start
When you start off, the motorcycle must be in perfect mecha­nical condition. For safety reasons, you should make a habit of performing an overall check of your motorcycle before each start.
The following checks should be performed: 1 CHECK THE OIL LEVEL
Insufficient oil results in premature wear and consequently to engine damage.
2 FUEL
Check that there is sufficient fuel in the tank; when closing the filler cap, check that the tank venting hose is free of kinks.
3 CHAIN
A loose chain can fall from the chain wheels; an extremely worn chain can tear, and insufficient lubrication can result in unnecessary wear to the chain and chain wheels. Excessive tensioning of the chain will put additional load on the com­ponents of the secondary drivetrain (chain, bearings of transmission and rear wheel). Aside from resulting prema­ture wear, if worst comes to worst the chain may rupture or the countershaft of the transmission may break.
4 TIRES
Check for damaged tires. Tires showing cuts or dents must be replaced. The tread depth must comply with the legal regulations. Also check the air pressure. Insufficient tread and incorrect air pressure deteriorate the driving performance.
5 BRAKES
Check correct functioning of the braking system. Check for sufficient brake fluid in the reservoir. The reservoirs have been designed in such a way that brake fluid does not need to be refilled even when the brake pads are worn. If the level of brake fluid falls below the minimum value, this indi­cates a leak in the braking system or completely worn out brake pads. Arrange for the braking system to be checked by a KTM specialist, as complete failure of the braking system can be avoided. Also check the state of the brake hose and the thickness of the brake linings. Check free travel at hand brake lever and foot brake lever.
6 CABLES
Check correct setting and easy running of all control cables.
7 COOLING FLUID
Check the level of cooling fluid when the engine is cold.
8 ELECTRICAL SYSTEM
Check correct functioning of headlamps, tail-lights, brake lights, indicators, control lamps and horn while the engine is running.
9 LUGGAGE
If you are taking luggage with you, check that this is securely fastened.

Starting when the engine is warm
1 Open the fuel tap 1. 2 Swing up the side stand. 3 Put the gear in neutral. 4 Leave throttle closed and kick the kickstarter briskly ALL THE WAY or
actuate the E-starter.
What to do when the engine is „flooded”
In the event of a fall, more fuel than necessary may get into the engine. In order to "pump the engine free", pull the hand decompression lever, fully rev up the engine, actuate the kickstarter 5 to 10 times or actuate the E­starter 2 times for 5 seconds each. Then, start the engine as described above. If the engine fails to start, unscrew the spark plug and dry it. NOTE: The carburetor has an accelerator pump. Every time you open the throttle, fuel will be injected into the intake passage. When starting, be sure that you open the throttle completely only once.
Starting off
Pull the clutch lever. Put the engine into first gear, slowly release the clutch lever and open throttle at the same time.

Shifting/Riding
You are now in first gear, refered to as the drive or uphill gear. Depending on the conditions (traffic, hill size, etc.), you can shift to a higher gear. Close throttle, at the same time pull clutch lever in and shift to the next higher gear. Let clutch lever go again and give gas. If you turned on the choke, make sure you turn it off again as soon as engine is warm. When you reach full speed through opening the throttle all the way, turn throttle back to 3/4; the speed hardly decreases although the engine will use less gas.

Changing the original position of the clutch lever
The adjusting screw 1 can be used for individual adjustment of the original position of the clutch lever, thus allowing adjustment to an optimal position for every hand size. Turning the adjusting screw clockwise reduces the distance between the clutch lever and the handlebar. Turning the adjusting screw counterclock­wise increases the distance between the clutch lever and the handlebar.
!
CAUTION
!
A
DJUSTMENT OF THE CLUTCH LEVER POSITION IS ONLY POSSIBLE WITHIN CERTAIN LIMITS
.
O
NLY TURN THE ADJUSTING SCREW MANUALLY AND NEVER APPLY EXCESSIVE FORCE.
Checking and adjusting the steering head bearing *
Check steering head bearing for play periodically. For check put motorcycle on stand so that the front wheel is off the ground. Now try to move the fork forward and backward. For readjusting, loosen the five pinch bolts
2
of the top triple clamp and turn steering stem bolt clockwise 3 until there is no more play. Don’t tighten the steering stem bolt all the way, otherwise the bearings will be damaged. With a plastic hammer, lightly rap on the triple clamp to release tension. Retighten the five pinch bolts to 20 Nm (15 ft.lb).
WARNING
I
F THE STEERING HEAD BEARING IS NOT ADJUSTED TO BE FREE OF PLAY, THE MOTORCY-
CLE WILL EXHIBIT UNSTEADY DRIVING CHARACTERISTICS AND CAN GET OUT OF CONTROL.
!
CAUTION
!
IF YOU DRIVE WITH PLAY IN THE STEERING HEAD BEARING FOR LONGER PERIODS, THE
BEARINGS AND SUBSEQUENTLY THE BEARING SEATS IN THE FRAME WILL BE DESTROYED
.
The steering head bearings should be regreased at least once a year (i.e. Shell Advance Grease).

Breather plug front fork
After every 5 hours of use for competitive racing, slacken the breather plugs
1 a few turns in order to relieve excess pressure from the inside of
the fork. To do this, place the motorcycle on a stand with the front wheel lifted off the ground. When riding the motorcycle mainly on street, it will be enough to have this job performed in the course of the periodical mainten­ance service.
!
CAUTION
!
E
XCESSIVE PRESSURE IN THE INTERIOR OF THE FORK CAN CAUSE LEAKS IN THE FORK. IF
YOUR FORK IS LEAKING
, IT IS RECOMMENDED TO OPEN THE BREATHER PLUGS BEFORE
HAVING THE SEALS REPLACED
.
Cleaning the dust sleeves of the telescopic fork
The dust-protection bellows 2 are to remove dust and coarse dirt particles from the fork tube. However, after some time, dirt may also get in behind the dust-protection bellows. If this dirt is not removed, the oil sealing rings located behind it may start to leak. Use a screwdriver to lever the dust-protection bellows out of the outer tubes and slide them downward.
Clean dust-protection bellows, outer tubes, and fork tubes thoroughly, and oil them thoroughly with silicone spray or engine oil. Then, push dust-pro­tection bellows into the outer tubes by hand.
How to change the handlebar position
The handlebar position can be readjusted by 22 mm. Thus, you can put the handlebar to the position that is the most convenient for you. The upper tri­ple clamp
3 includes 2 bores arranged at a distance of 15 mm (0,6 in) from
one another. The bores at the handlebar support
4 are offset from the cen-
ter by 3.5 mm (0,13 in). Accordingly, you can mount the handlebar in 4 different positions.
For this purpose, remove screws
5 of the handlebar clamps and screws 6
of the handlebar support. Position handlebar support, and tighten screws 6 to 40 Nm (30 ft.lb). Mount handlebar and handlebar clamps, and tighten screws 5 to 20 Nm (15 ft.lb). The gap between handlebar support and handlebar clamps is to be of equal size in the front and in the rear.

Changing the spring preloading of the shock absorber
The spring preload can be changed by turning the adjusting ring 1. For this purpose, you should dismount the shock absorber and clean it thoroughly.
NOTE: – Before changing the spring preload note down the basic setting, e.g.
how many threads are visible above the adjusting ring.
– One rotation of the adjusting ring 1 changes the spring pretension by
approximately 1,75 mm (0,07 in).
Loosen the clamping screw
2 and use the hook wrench contained in the
vehicle tool set to turn the adjusting ring as desired. Turning it counter­clockwise will reduce the preload, turning it clockwise will increase the preload. After readjusting the clamping screw
2, tighten it to 8 Nm (6 ft.lb)

Pivot bearing
The pivot bearing 3 for PDS suspension struts at the swinging fork is Teflon-coated and must not be lubricated with either grease or other lubri­cants. Grease and other lubricants cause the Teflon coat to dissolve, whereby the bearing’s lifecycle will be reduced dramatically.
When cleaning your bike with a high-pressure cleaner, do not aim the high­pressure spray directly at the pivot bearing.
Check chain tension
To check the chain tension, park the motorcycle. Press chain upward at the end of the chain sliding component. The distance between chain and swing arm should be approx. 15 mm (0.6 in). In the course of this procedure, the upper chain portion A must be taut (see illustration). If necessary, correct chain tension.
WARNING

MAY LEAD TO AN UNSTABLE BEHAVIOR OF YOUR MOTORCYCLE
.
NOTE: The large adjusting range of the chain adjusters (32mm) allows you to use different secondary ratios in combination with the same chain length. The chain adjusters 5 can be rotated around 180°.
Chain maintenance
For long chain life, good maintenance is very important. Chains without O­rings should be cleaned in fireproof solvent regularly and afterwards treated with hot grease or chain spray (i.e. Shell Advance Bio Chain). O-ring chains on the other hand are very simple to clean. The best way is to use lots of water, but never use brushes or cleaning liquids. After letting the chain dry, you can use a special O-ring chain spray (i.e. Shell Advance Bio Chain).
WARNING
NO LUBRICATION IS ALLOWED TO REACH THE REAR TIRE OR THE BRAKE DISKS
, EITHER-
WISE THE ROAD ADHERENCE AND THE REAR WHEEL BRAKING EFFECTS WOULD BE STRON- GLY REDUCED AND THE MOTORCYCLE COULD EASILY LOSE CONTROL.
!
CAUTION
!
W
HEN MOUNTING THE CHAIN MASTERLINK CLIP, THE CLOSED SIDE OF THE MASTERLINK
CLIP MUST POINT IN RUNNING DIRECTION
.
Also check sprockets and chain guides for wear, and replace if necessary.
Chain wear
In order to check the chain wear, regard the following indications: Shift the gear into idling and pull the upper chain strand with approx. 10-15 Kilogramm (33 lb) upwards (see figure). Now one can measure a space of 18 chain reels at the lower chain strand. The chain should be replaced at the latest when a space of 272 mm (10.70 in) is measured. Chains do not always wear off evenly, therefore repeat the measurement at different pla­ces on the chain.
NOTE: If you mount a new chain, the sprockets should also be replaced. New chains wear faster if used on old used sprockets.

General information about KTM disc brakes
BRAKE CALIPERS: The brake calipers of this series use a „floating” mount. This means that the brake calipers are not solidly attached to the caliper support, which enables them to „float” for maximum braking contact.
BRAKE PADS: Brake pads are equipped with a sintered lining (TOSHIBA TT2701) in the front and an organic lining in the back (FERODO ID450). These linings make up the best mix of controllability, braking power and life. The type of lining is specified on the backside of the brake pads and also entered in the approval documents.
For competition purposes, also other types of linings are available: FRONT TOSHIBA H38 (sintered) - less braking power, longer life; for wet,
slippery terrain. FERODO ID450 (organic) - good braking power, shorter life; for dry terrain, cheaper.
REAR GOLDFREE KBA60878 (sinter) - higher braking power, longer life.
FERRIT 222 (organic) - better controllability, shorter life.
BRAKE DISCS: Due to wear, the thickness of the brake disc in the area of the contact face
1 of the brake pads decreases. At their thinnest point A, the brake
discs must not be more than 0.40 mm (0,016 in) thinner than the pad's nominal thickness. Measure the nominal thickness in a location
B outside
the contact face. Check wear in several locations.
WARNING
–B
RAKE DISCS SUFFERING FROM WEAR GREATER THAN 0,4 MM (0,016 IN) CONSTI-
TUTE A SAFETY RISK. HAVE THE BRAKE DISCS REPLACED IMMEDIATELY AS SOON AS THEY REACH THE WEAR LIMIT
.
–H
AVE ANY REPAIRS ON THE BRAKE SYSTEM BE PERFORMED BY A KTM DEALER
BRAKE FLUID RESERVOIRS: The brake fluid reservoirs on front and rear wheel brakes have been desi­gned in such a way that even if the brake pads are worn it is not necessary to top up the brake fluid. If the brake fluid level drops below the minimum level either the brake system has a leak or the brake pads are completely worn. In this case, consult an authorized KTM dealer immediately.
BRAKE FLUID: KTM fills the brake systems with SHELL ADVANCE BRAKE DOT 5.1 brake fluid, one of the best brake fluids that is currently available. We recommend that you continue to use it. DOT 5.1 brake fluid is based on glycol ether and of an amber color. If you do not have any DOT 5.1 for refilling, you may use DOT 4 brake fluid. However, you should replace it as soon as possible by DOT 5.1. Never use brake fluid DOT 5. The color of this silicon oil-based product is purple red. The gaskets and brake hoses of KTM motorcycles are not designed for DOT 5 brake fluid!
WARNING
HAVE THE BRAKE FLUID CHANGED AT LEAST ONCE ANNUALLY. IF YOU WASH YOUR
MOTORCYCLE OFTEN
, THE BRAKE FLUID SHOULD BE CHANGED EVEN MORE FREQUENTLY.
B
RAKE FLUID TENDS TO ABSORB WATER. THEREFORE, VAPOR POCKETS MAY FORM IN
"
OLD"
BRAKE FLUIDS EVEN AT LOW TEMPERATURES, CAUSING THE BRAKE SYSTEM TO
FAIL
.
Adjusting of free travel at the hand brake lever
Free travel at the hand brake lever may be readjusted by using adjustment screw
2. In this way, the position of the point of pressure (i.e., the resi-
stance you feel on the hand brake lever when the brake pads are pressed against the brake disc) can be adjusted for any hand size.
!
CAUTION
!
A
T THE HAND BRAKE LEVER, FREE TRAVEL MUST AT LEAST BE 3 MM (0.1 IN). ONLY
THEN MAY THE PISTON IN THE HAND BRAKE CYLINDER BE MOVED
(TO BE RECOGNIZED BY
THE GREATER RESISTANCE OF THE HAND BRAKE LEVER
). IF THIS FREE TRAVEL IS NOT PRO-
VIDED, PRESSURE WILL BUILD UP IN THE BRAKING SYSTEM, AND THE FRONT-WHEEL BRAKE MAY FAIL DUE TO OVERHEATING

Checking of brake fluid level - front brake
The brake fluid reservoir is linked with the hand brake cylinder at the hand­lebar and the reservoir is provided with an inspection glass. With the reser­voir in a horizontal position, the brake fluid level should not drop below the middle of the glass.
WARNING
I
F THE BRAKE FLUID LEVEL DROPS BELOW THE MINIMUM EITHER THE BRAKE SYSTEM HAS A
LEAK OR THE BRAKE PADS ARE COMPLETELY WORN
. IN THIS CASE, CONSULT AN
AUTHORIZED
KTM DEALER IMMEDIATELY.

Tires, air pressure
Tire type, tire condition, and air pressure level affect the way your motor­cycle rides, and they must therefore be checked whenever you are getting ready to go anywhere on your motorcycle. – Tire size can be found in the technical specifications and in their homolo-
gation certificate
– Tire condition has to be checked every time you want to ride your
motorcycle. Before leaving, check tires for punctures and nails or other sharp objects that might have become embedded in them. Refer to the specific regulations in your country for minimum tire tread requirements. We recommend you replace the tires at the latest when the tread is down to 2 mm (0.08 in).
– Tire pressure should be checked regularly on a “cold” tire. Proper pres-
sure ensures optimum driving comfort and extends the life of your tires.

Checking spoke tension
The correct spoke tension is very important for the stability of the wheels and thus for riding safety. A loose spoke causes the wheel to become unba­lanced and before long other spokes will have come loose. Check spoke tension, especially on a new motorcycle, in regular intervals. For checking, tap on each spoke with the blade of a screwdriver (see photo). A clear tone must be the result. Dull tones are indicators of loose spokes. If necessary, have the spokes retightened and the wheel centered by a KTM dealer.
WARNING
S
POKES CAN TEAR IF YOU CONTINUE TO RIDE WITH THEM LOOSE. THIS MAY LEAD TO AN
UNSTABLE HANDLING OF YOUR MOTORCYCLE

Cooling system
Coolant is circulated by a water pump 1 located in the engine. When the engine is cold the coolant circulates only through the cylinder and the cylin­der head. After the engine has reached its operating temperature (about 70°C, 158°F), the thermostat
2 opens and the coolant is also pumped
through both aluminum radiators. Air blowing in through the radiators cools the coolant. The slower the speed of the motorcycle, the less the coolant is cooled down. Dirty radiators also reduce the cooling efficiency. Pressure induced by heating of the coolant in the system is controlled by a valve in the radiator cap
3; a water temperature rising up to 120° C
(248° F) is admissible, without fear of problems.

Cleaning the air filter *
A dirty air filter impairs the air-flow rate, reduces the engine performance, and increases the fuel consumption. In extreme cases, dirt may even get into the engine and cause damage. Therefore, change the air filter in regular intervals. For this purpose, rotate the two quick-release fasteners
1 counter-clock-
wise and pull them outward up to the stop, pull the filter box cover forward and remove it. Unhook the filter holding brackets
2 at the bottom, swing
them sideways and take the air filter
3 together with the filter support 4
out of the filter box.

.
Thoroughly wash the air filter in special cleaning fluid and allow it to dry well. Only press out the filter, do not wring it out under any circumstances. Oil the dry air filter with a high-grade filter oil. Also clean the air filter box. Check carburetor collar for damage and that it is filled correctly. Mount the air filter on the filter support. Apply grease to the face
A of the
filter to improve its sealing properties. Mount the filter together with the fil­ter support in the filter box, making sure to properly center them, and fix them with the filter holding bracket.
Replacing the glass fiber yarn packing of the silencer *
Aluminum silencers are filled with glass fiber yarn to muffle noise. The effect of heat causes the glass fiber yarn to become loose. This may lead to a loss of performance and reduce the silencer's muffling power. By experi­ence, the front glass fiber yarn packing
5 needs to be replaced more often
than the rear silencing mat
6.
For this purpose, remove the silencer from the vehicle and dismount the front cap
7. Pull the front glass fiber yarn packing together with the inner
exhaust pipe
8 out of the silencer. Clean the front inner exhaust pipe.
To facilitate the mounting procedure, you can make a mounting tool
9 out
of wood, plastic, or metal. Insert the mounting tool into the inner pipe and mount the glass fiber packing. Push the inner pipe containing the packing into the silencer such that the slot engages the web
C. Use a blunt ended
object to stuff the glass fiber yarn packing all the way into the silencer, and mount the front cap.
To change the rear silencing mat, start by removing the front packing and the inner exhaust pipe. Then, drill open the rivets and remove the end cap.
NOTE! In every exhaust repair procedure, the O-rings must be replaced by new ones. Glass fiber yarn packings are available at your licensed KTM mechanic.
WARNING
THE EXHAUST SYSTEM BECOMES VERY HOT WHILE THE MOTORCYCLE IS RUNNING. TO
AVOID BURNS
DO NOT START WORK ON THE EXHAUST SYSTEM UNTIL IT HAS PROPERLY

Checking the adjustment of the hand decompression release cable *
Start the engine and, at idling speed, slowly pull the hand decompression lever until you can feel the thumping of the rocker arm on the lever. The backlash until said thumping should be approx. 10mm, measured at the lever's outer end. If necessary, correct this backlash. To adjust move back the protective cover
1, loosen the counter nut 2 and
correct the adjustment screw
3 accordingly. Tighten counter nut and push
back protective cover.
!
CAUTION
!
IF THERE IS NO PLAY IN THE DEKO-LEVER, THIS CAN RESULT IN ENGINE DAMAGE.
NOTE: No adjustment need be made to the automatic decompressor.
Adjusting the throttle cables *
The throttle grip should always provide for a backlash of 3-5mm. Besides, with the engine running, the idling speed must not change if you turn the handlebar all the way to the left or right. To adjust the throttle cables, dismount the seat and the tank together with spoilers. Slide back the protection cover
4. Loosen the counter nut 5 and
turn the adjusting screw
6 accordingly. Turning the adjusting screw coun-
terclockwise will reduce the backlash, turning the adjusting screw clockwise will increase the backlash. Tighten the counter nut and check whether the throttle grip can be actuated smoothly. Mount tank and seat.
Checking the oil level of the hydraulic clutch
To check the oil level in the master cylinder of the clutch remove the cover. For this purpose, remove screws
7 and cover together with the rubber
boot
8. The oil level in the horizontal-standing master cylinder should be
4 mm below the upper edge. If necessary add SAE 10 hydraulic oil (e.g. Shell Naturelle HF-E15).
!
CAUTION
!
O
NLY USE SAE 10 MINERAL HYDRAULIC OIL TO REFILL THE MASTER CYLINDER. NEVER
USE BRAKE FLUID

CARBURETOR – Adjust idling (MX-FCR39) *
Idling adjustment of the carburetor strongly affects the engine’s starting behavior. That is, an engine whose idling speed is adjusted correctly will be easier to start than one whose idling speed has not been adjusted correctly.
The idle speed is controlled by means of the adjusting wheel
1 and the
mixture control screw
2. The adjusting wheel is used to adjust the basic
setting of the slide. The mixture control screw is used to control the idle mixture which arrives at the engine by way of the idle system. Clockwise turning reduces the fuel quantity (lean mixture), counterclockwise turning increases the fuel quantity (rich mixture).
TO ADJUST IDLING CORRECTLY, PROCEED AS FOLLOWS: 1 Turn in mixture control screw
2 up to the stop, and turn it back out to
the basic position (see tecnical date engine) 2 Warm up the engine 3 Use the adjusting wheel
3 to set the normal idle speed (1400 - 1500
rpm). 4 Turn mixture control screw
2 slowly clockwise until idling speed starts to
decrease. Memorize this position, and turn mixture control screw slowly
counterclockwise until the idling speed will decrease again. Adjust the
point of the highest idling speed between these two positions. If, in the
course of this procedure, the speed undergoes a relatively high increase,
reduce the idle speed to a normal level and repeat the procedure speci-
fied in 4. Serious competitive racers will choose a setting approx. 1/4
turn (clockwise) leaner than this ideal value because their engine will
heat up more when used in competitions.
NOTE: If you fail to obtain a satisfying result by following the procedure
described above, an incorrectly dimensioned idling nozzle may be the
cause. In case:
a) the mixture control screw has been screwed in up to the stop without
causing any change in rotational speed, a smaller idling jet has to be
installed;
b) the engine dies when the mixture control screw is still open by
2 turns, a larger idling jet needs to be selected;
Naturally, in cases of jet changes, you have to start your adjusting work
from the beginning. 5 Then, use the adjusting wheel to set the desired idle speed. 6 In cases of greater changes in outside temperature and extremely
different altitudes, the idling speed should be readjusted.
Basic information on carburetor wear
As a result of engine vibrations, throttle valve, jet needle, and needle jet are subjected to increased wear. This wear may cause carburetor malfunction (e.g., overly rich mixture). Therefore, these parts should be replaced after 200 hours.
Adjusting the mixture control screw *
Especially on the EXC models, accessing the mixture control screw is diffi­cult. For this reasons, we have created an appropriate special tool. Introduce the special tool into the bore
A at the carburetor bottom. Press
the tool slightly upward and turn the adjusting wheel
3until the tool enga-
ges the slot of the mixture control screw
2.
Now, you can go about adjusting the screw. Marks were provided on the adjusting wheel, making it easier to keep track of the turns.
Checking the float level (float height) *
For this purpose, dismount the carburetor and remove the float chamber. Hold the carburetor in a slanted position such that the float will abut the float needle valve but not compress it (see photo). Now, use a sliding caliper to measure the distance
H between the casing
edge and the float's upper edge. The float height
H is to be 9mm.
If the float height does not correspond to the desired value, check the float needle valve and, if necessary, replace it.
If the float needle valve is o.k., you can adjust the float height by bending of the float lever
4.
Mount the float chamber, install the carburetor, and adjust the idle speed.

Draining of float chamber of the carburetor
Following every wet cleaning procedure, the float chamber of the carbure­tor should be drained in order to remove any water that may have penetra­ted into it. Water in the float chamber causes malfunction.
Perform this task on a cold engine. Close the fuel tap and place a cloth underneath the carburetor, which is able to absorb any escaping fuel. Unscrew the plug 1 and clean it with compressed air. Check the O-ring and reinstall the plug. Open the fuel tap and check the float chamber for leaks.

Oil circuit
Via the long oil screen 2, the oil pump 1 draws engine oil from the oil sump of the transmission. This engine oil flows through an oil line 3 into the cylinder head for camshaft lubrication 4; the oil quantity is controlled by the jet screw 5. An oil duct branches off to the long oil filter 6 where the coarser particles contained in the engine oil are filtered away. Then, the engine oil arrives at the short oil filter 7 which also filters the fine particles. Now, the purified engine oil is pumped past the bypass valve 8 to the con­rod bearing 9 and sprayed from below onto the piston through a nozzle bk. The second oil pump bl draws the engine oil via the short oil screen bm out of the crankcase, thereby lubricating the transmission gears bn.
Checking the engine oil level
The engine oil level can be checked with the engine being either warm or cold. Place the motorcycle in an upright position and on a horizontal surface (not on the side stand).
If the engine is cold, the engine oil must be visible at the lower edge of the inspection glass
A.
If the engine is warm, the engine oil must be visible up to the upper edge of the inspection glass
B.
Replenish the engine oil, if necessary.
!
CAUTION
!
I
NSUFFICIENT AMOUNTS OF OR LOW-GRADE ENGINE OIL LEAD TO PREMATURE WEAR IN
THE ENGINE
.
If the inspection glass is heavily soiled (e.g. after a race in muddy terrain), the engine oil level can also be measured with the oil dipstick. For this pur­pose, unscrew the dipstick and wipe it clean with a cloth. Screw the dipstick back in and screw it out again. If the engine is warm, the oil level should be near the MAX mark
C (+0mm –5mm) (+0in –0,2in).

Changing the engine oil *
NOTE: WHEN CHANGING THE ENGINE OIL
, IT IS NECESSARY TO CLEAN THE SHORT AND
LONG OIL SCREENS AND TO REPLACE BOTH OIL FILTERS
.
Engine oil has be changed with the engine being at operating temperature.
!
CAUTION
!
A
N ENGINE AT OPERATING TEMPERATURE AND THE ENGINE OIL IT CONTAINS ARE VERY
HOT
- DO NOT BURN OR SCALD YOURSELF!
Place the motorcycle on a horizontal surface, remove the plug
1 and allow
the oil to drain into a receptacle. Clean plug (with magnet) thoroughly. Once the entire oil has been drained, clean the sealing surface, mount the plug together with the sealing ring and tighten it to 20 Nm (15 ft.lb).
CLEANING THE SHORT OIL SCREEN The short oil screen
2 is accommodated in the hex-socket plug 3 at the
engine bottom. Insert a pin-type key into the plug and tap on the key a few times with a hammer in order to relieve the stress acting on the plug. Dis­mount the oil screen, clean the components thoroughly and blow compres­sed air through them. Check the O-rings for damage and, if necessary, replace them. Mount the oil screen together with the plug again and tigh­ten the plug to 10 Nm (7 ft.lb).
CLEANING THE LONG OIL SCREEN The long oil screen is accommodated in the hexagon plug
4 adjacent the
engine number. Dismount the plug together with the oil screen, clean the components thoroughly and blow compressed air through them. Check the O-rings for damage and, if necessary, replace them.
To mount the long oil screen
5, place it on an approx. 300 mm (12 in) long
pin-type key or a similar tool. Insert the pin-type key through the opening into the bore of the opposite engine casing wall. Then, push the oil screen into the engine casing as far as possible. Remove the pin-type key, mount the plug and tighten it to 15 Nm (11 ft.lb).

TROUBLE SHOOTING
If you let the specified maintenance work on your motorcycle be carried out, disturbances can hardly be expected. Should an error occur nevertheless, we advise you to use the trouble shooting chart in order to find the cause of error. We would like to point out that many operations cannot be performed by oneself. In case of uncertainty, please contact a KTM-dealer.
TROUBLE
Engine doesn’t crank (E-starter).
Engine cranks but doesn’t start (E-starter). Engine will not start (Kick­starter).
Engine fails to idle
CAUSE
Operating errror
Blown fuse
Discharged battery.
Operating error
The motorcycle has been out of operation for a longer period of time. Therefore old fuel has accu­mulated in the float chamber
Fuel supply interrupted
Flooded engine
Sooty or wet spark plug
Electrode gap too large
Spark plug connector or spark plug faulty
Short circuit cable scored in wiring harness, emergency OFF switch or short circuit button faulty
The plug connection of the CDI­unit, the pulse generator or the ignition coil has oxydized
Water in carburetor or jets blocked
Glogged idling jet
Oncorrect adjustment of adjusting screws on carburetor
Defective spark plug
Defective ignition system
REMEDY
Turn on the emergency-OFF switch (Australia only)
Dismount the left paneling and the filter box cover and replace the fuse in the starter relay.
Recharge the battery and investigate the causes for dischar­ging; contact a KTM dealer.
Open fuel tap, tank fuel, actuate choke. Pay attention to star­ting information (see driving instructions).
The easily inflammable components of the new fuels evapo­rate during longer periods of standstill. When the motorcycle has been out of operation for more than a week, it is therefore recommended to drain the old fuel from the float chamber. The engine will immediately start off when the float chamber is filled with new fuel.
Close fuel tap, loosen fuel hose at carburettor, lead into a basin and open fuel tap – if fuel leaks out, the carburetor might need cleaning – if no fuel leaks out, check tank ventilation, i.e. clean fuel tap
In order to "pump the engine free", pull the hand decompres­sion lever, fully rev up the engine, actuate the kickstarter 5 to 10 times or actuate the E-starter 2 times for 5 seconds each. Then, start the engine as described above. If the engine fails to start, unscrew the spark plug and dry it.
Clean and dry the spark plug or exchange it, respectively
Adjust spark plug elektrode gap to 0,6 mm
Dismount spark plug, connect ignition cable, hold to ground (blank place on engine) and actuate starter, a strong spark must be produced at the spark plug – If no spark is created exchange the spark plug. – If the new spark plug doesn't produce a spark either, dis-
connect the spark plug connector from the ignition cable,
hold it a distance of approx. 5 mm from ground and start. – If a spark now occurs, replace spark plug cap – If no spark is produced, control ignition system
Dismount the fuel tank, disconnect the black/yellow cable from the cable of the emergency-OFF switch and the short-circuit button, respectively, and check the ignition spark. If a spark is generated, look for the problem in the short-circuit circuit.
Remove the seat and the fuel tank. Clean the plug connection and treat it with contact spray
Dismount and clean carburetor
Disassemble carburetor and clean jets
Have carburetor adjusted
Replace spark plug
Have ignition system checked

Should you desire to make a pause over a longer space of time, please observe the following instructions: – Clean motorcycle thoroughly (see chapter: CLEANING) – Change engine oil, short and long oil filters (old engine oil contains aggressive contaminations). – Check antifreezer and amount of cooling liquid. – Warm up the engine once again, close the fuel cock and wait until the engine dies. Then open the drain plug of the float chamber
to remove the remaining fuel.
– Remove spark plug and fill in approx. 5 ccm of engine oil into the cylinder through the opening. Actuate kick-starter 10 times in
order to distribute the oil onto the cylinder walls and mount the spark plug.
– Set piston to compression so that the valves will be closed (slowly operate the kickstarter, until you can hear the automatic
decompressor click (release)) – Let fuel flow out of tank into an appropriate container. – Correct tire pressure. – Lubricate pivot points of the control levers, foot rests, etc. as well as the chain. – Service the shock absorber linkage – Disassemble and charge battery (see chapter: BATTERY). – The storage place should be dry and not subject to excessive temperature fluctuations. – Cover the motorcycle with an air permeated tarpaulin or blanket. Do not use non air permeable materials as a possible humidity
might not be able to escape and could cause corrosion.
!
CAUTION
!
I
T WOULD BE VERY BAD TO LET THE ENGINE RUN FOR A SHORT TIME DURING THE STORAGE PERIOD. THE ENGINE WOULD NOT GET WARMED UP ENOUGH
AND THE THUS DEVELOPED STEAM WOULD CONDENSE DURING THE COMBUSTION PROCESS AND CAUSE THE VALVES AND EXHAUST TO RUST
.
RE-INITIATION AFTER TIME OF STORAGE
– Mount the charged battery (regard polarity). – Fill up tank with fresh fuel. – Check motorcycle as before each start (see driving instructions). – Take a short, careful test ride first.
NOTE: Before you put your motorcycle away for the winter, you have to check all parts for their function and wear. Should any ser­vice jobs, repairs, or any refitting be necessary, you should have them carried out during the off-season (lower workload at mechanics’ shops). This way, you can avoid the long waiting times at your mechanic at the beginning of the next biking season.
STORAGE
Clean your motorcycle regularly in order to maintain the beauty of its plastic surfaces. The best manner would be to use warm water that has been mixed with a normal brand-name washing detergent and a sponge.
The hard dirt can be removed before washing with the help of a soft water jet.
!
CAUTION
!
NEVER CLEAN YOUR MOTORCYCLE WITH A HIGH-PRESSURED CLEANER OR A HIGH-PRESSURED WATER JET. THE WATER COULD OTHERWISE RUN INTO THE
ELECTRICAL COMPONENTS
, CONNECTORS, SHEATHED CABLES, BEARINGS, CARBURETOR ETC. AND CAUSE DISTURBANCES OR LEAD TO A PREMATURE
DESTRUCTION OF THESE PARTS
.
– You should use normal brand-name detergents to clean the motorcycle. Especially dirty parts should be cleaned additionally with
the help of a paint brush.
– After the motorcycle has been rinsed with a soft water jet, it should be dried by air pressure and a cloth. Drain the float chamber of
the carburetor. Then take a short drive until the engine has reached the working temperature and also use the brakes. By warming these components, the residual water can evaporate from inaccessable parts of the engine and the brakes.
– Slide back the protective covers on the handlebar-mounted instruments so that any water that may have seeped into this part of
the motorcycle is allowed to evaporate.
– Once the motorcycle has cooled down, oil or grease all sliding and bearing points. Treat the chain with a chain spray. Also oil the
fuel tap.
– To avoid any malfunction of the electric system, you should treat emergency-OFF switch, short-circuit button, light switch and
socket connectors with a contact spray.
CLEANING
In the event that the motorcycle is also used in winter and on roads where one has to expect salt spraying, you will have to take pre­cautions against the aggressive road salt. – clean motorcycle thoroughly and let it dry after each riding – treat engine, carburetor, swing arm, and all other bare or galvanized parts (except for brake discs) with a wax-based anti-corrosion
agent.
WARNING
K
EEP ANTI-CORROSION AGENT FROM GETTING INTO CONTACT WITH THE BRAKE DISCS, FOR OTHERWISE THIS WILL SIGNIFICANTLY REDUCE THE BRAKING POWER
