Fitting of the drive chain

The required length of the drive chain depends on chassis and transmission ratio and the chain is
therefore not included in the engine's scope of supply.
¿ Note:
BRP-Rotax recommends o-ring drive chains by ROTAX Premium.
Æ
Use a chain with the length corresponding to the selected transmission ratio of
dimension 7.75 x 4.6 x 4.5.
Æ
Place the chain on the sprocket on the clutch and on the sprocket on rear axle.
Æ
Verify chain alignment between front and rear chain sprocket with a straight edge.
Correct as required by shifting sprocket adapter along rear axle.
p Warning: Pay attention to instructions of the chassis manufacturer regarding the drive
chain alignment.
Æ
Establish required chain tension (Sag = +/- 5 mm / +/- 0.20 in.) by shifting the
engine.
Æ
Fasten engine on the chassis.
p Warning: Take note of the advice of the chassis manufacturer regarding engine
attachment to chassis.
p Warning: This cover serves merely as splash protection against the grease on the drive
chain, but is no protection against contact with the moving parts of the
centrifugal clutch and the drive train!
p Warning: During kart operation, beware of any contact of body or clothing with moving
parts of the kart (drive chain, rear axle and wheels). Risk of injury.
