Checking the coolant level
The coolant should be 10 mm (0,4 in) above the radiator fins when the engine is
cold (see illustr.). In the event of the coolant being drained, always fill and bleed
the system.
WARNING
IF POSSIBLE, ALWAYS CHECK LEVEL OF COOLING LIQUID WHEN ENGINE IS COLD. IF YOU
HAVE TO OPEN THE RADIATOR CAP WHEN THE ENGINE IS HOT
, USE A RAG TO COVER THE
CAP AND OPEN SLOWLY TO RELEASE PRESSURE
.

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 unravelled, which
can reduce both overall performance and the performance of the silencer. Experi-
ence has shown that the front glass fiber pack
3 must be replaced more often
than the rear pack
4.
To replace the front glass fiber yarn pack, remove the silencer. Remove the front
cap
5, pull the front glass fiber yarn pack out of the silencer, mount a 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

Always renew the O-rings

Glass fiber yarn packs are available in your KTM store.
