Exhaust system *

Aluminium silencers are filled with glass fiber yarn. If exposed to heat for
longer periods of time, however, the glass fiber yarn pack will come unra-
velled, which can reduce both overall performance and the performance of
the silencer. Experience has shown that the front glass fiber pack
be replaced more often than the rear pack
To replace the front glass fiber yarn pack, remove the silencer. Remove the
front cap
new pack on the internal exhaust pipe, insert the internal exhaust pipe into
the silencer and replace the cap.
To replace the rear glass fiber yarn pack, drill the rivets open and remove
the rear cap
NOTE:
Always renew the O-rings
Glass fiber yarn packs are available in your KTM store.

Draining of float chamber of the carburetor
Following every wet-cleaning procedure, the float chamber of the carbure-
tor should be drained in order to remove any water that may have penetra-
ted into it. Water in the float chamber leads to engine malfunction.
Make sure you do this while the engine is cold. Close the fuel tap, and place
a cloth under the carburetor, which is capable of absorbing the leaking fuel.
Unscrew the plug
together with gasket, open fuel tap, and check float chamber for leaks.
