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

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

turn the adjusting screw 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
9
the rubber boot . The oil level in the horizontal-standing master cylin-
der should be 4 mm below the upper edge.
If necessary, fill up with biodegradable hydraulic oil SAE 10 (e.g. Shell
Naturelle HF-E15).Biodegradable hydraulic oil is available from your
KTM dealer (50ml).

Bleeding of the hydraulic clutch

For bleeding, the cover of the master cylinder of the clutch needs to be
removed. For this purpose, remove screws
9
with rubber bellows . At the slave cylinder of the clutch, remove the blee-
bl
der nipple . At its place, mount the bleeder syringe
SAE 10 hydraulic oil. Refill oil, until oil is discharged from the bore
master cylinder in a bubble-free state. Make sure that the oil does not over-
flow. The bleeder syringe can be purchased at your KTM dealer.Having
completed the bleeding procedure, you have to verify that the oil level in
the master cylinder is correct.If necessary, fill up with biodegradable
hydraulic oil SAE 10 (e.g. Shell Naturelle HF-E15).Biodegradable hydrau-
lic oil is available from your KTM dealer (50ml).
