Section 4 - BASIC MAINTENANCE
4.1 CENTRIFUGAL CLUTCH
The engine has a low maintenance dry centrifugal clutch. The following prescriptions, if
carefully followed, will allow a clutch longlife.
When starting the engine, make sure that the brake pedal is fully pressed to avoid
sudden accelerations.
WARNING:
Once the engine is started, avoid useless accelerations which can overheat and
deteriorate the clutch. Oil the chain before each session. Immediately after each race or
test, check the engine sprocket . Replace if necessary.
A bad alignment of the engine sprocket with the axle sprocket or the lack of oil will
damage irreparably the sprocket.
Check the clutch:

every 5 hours of use.

When metallic noises are heard inside the clutch.

If the kart dragging speed exceeds 6000 RPM.

Every time the clutch has overheated (presence of smoke or smell of burning).
To check the clutch, you must remove the clutch cover and the clutch drum.
Replace the clutch:

whenever the thickness of the friction material (see drawing) is lower than 1.5mm on
point A of the clutch or if the body diameter is lower than 83mm.

Whenever the external friction material in the A portion of the clutch is very rough
(wear or degradation of the friction material due to overheating).
WARNING:
In case the friction material has been totally worn out and there has been a metal
contact between the clutch body and the clutch drum, it is necessary to replace the
clutch drum. See drawing.
