5. 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 supply volume of the engine.
Use a chain with the length corresponding to the selected transmission ratio of
dimension 7.75 x 4.6 x 4.5.
Place chain on sprocket at the clutch and on the sprocket on rear axle.
Verify chain alignment between front and back chain sprocket with a straight edge.
Correct as required by shifting sprocket adapter along rear axle.
Warning: Pay attention to instructions of the chassis manufacturer regarding the drive chain
alignment.
Establish required chain tension (Sag = +/- 5 mm / +/- 0.20 in) by shifting of the
engine.
Fasten engine on the chassis
Warning: Take note of advice of the chassis manufacturer regarding engine suspension on
chassis.
Note: If you find in the equipment carton a synthetic strap with the dimensions 800 x 65
mm (31.50 x 2.56 in.) it may be used to cover the drive chain. This cover can be
attached via the holes provided on the lower coolant hose with a cable tie. The
cover should be routed in a curved path from the lower coolant hose to the chain
guard fixtures provided on the chassis. The necessary holes for securing the cover
on the two supports have to be made according to the position on the chassis.
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!
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.
