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.
ADJUSTMENT OF THE CLUTCH LEVER POSITION IS ONLY POSSIBLE WITHIN CER-
TAIN LIMITS. ONLY TURN THE ADJUSTING SCREW MANUALLY AND NEVER APPLY
EXCESSIVE FORCE.
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 [2] and cover [3] together with the rubber
boot [4]. The oil level in the horizontal-standing master cylinder should be 4
mm below the upper edge.
If necessary, fill up with biodegradable hydraulic oil SAE 10 (e.g. Motorex
Kupplungs-Fluid 75).Biodegradable hydraulic oil is available from your KTM
dealer (50ml).
KTM USES BIODEGRADABLE HYDRAULIC OIL FOR THE HYDRAULIC CLUTCH CON-
TROL. NEVER MIX BIODEGRADABLE HYDRAULIC OILS WITH MINERAL OILS. NEVER
REFILL WITH MINERAL HYDRAULIC OIL OR BRAKE FLUID.
Bleeding of the hydraulic clutch
If the clutch lever starts to feel unresponsive, the clutch control system needs
to be bled. You will need a bleeder syringe (special tool) and biodegradable
hydraulic oil. Both are available from your KTM dealer.
Turn the handlebar until the master cylinder is in a horizontal position, remove
the screws [2], the cover [3] and the rubber boot [4].
Fill the bleeder syringe [6] with biodegradable hydraulic oil (Motorex Kupplungs-
fluid 75). Remove the bleeder screw [5] from the slave cylinder and mount
the bleeder syringe. Press oil into the system until the oil runs out of the hole
[7] in the master cylinder without bubbles. Occasionally extract the oil from
the master cylinder reservoir to keep it from overflowing.
After you finish bleeding, remove the bleeder syringe, mount the bleeder screw,
correct the oil level in the reservoir and mount the cover (see above).
