Exhaust system
The silencer is filled with glass-fiber yarn for damping. When in use, the
glass-fiber yarn becomes loose or coked with oil carbon. This can lead to a
power loss and a reduction of the silencer damping. The glass-fiber yarn
packing can be replaced in a few easy steps.
To replace, remove the silencer from the vehicle and mark the position of
the outer tube
1 to the inner tube 2. Remove screws 3 and the end cap
4
. Pull of the outer tube and remove the old glass-fiber yarn packing 5
from the inner tube. Thoroughly clean all parts.
To assemble, mount a new glass-fiber yarn packing onto the inner tube (see
illustration) and slide into the outer tube. Mount end cap and fix with
screws
1. Before tightening the screws, turn the outer tube until they
match the positions you marked. Mount the silencer and check the exhaust
system for tightness.
NOTE: Glass fiber yarn packages are offered by your licensed KTM dealer.

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
6 and cover 7 together with
the rubber boot
8. The oil level in the horizontal-positioned master
cylinder 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
To bleed, the cover of the master cylinder of the clutch needs to be
removed. For this purpose, remove screws
6 and take off the cover
7together with the rubber bellows 8. At the slave cylinder of the clutch,
remove the bleeder nipple
bk. In its place, mount the bleeder syringe 9
which is filled with SAE 10 hydraulic oil. Refill oil, until oil is discharged from
the bore
bl of the master cylinder in a bubble-free state. Make sure that the
oil does not overflow. The bleeder syringe can be purchased from 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-15).
