RECOMMENDATIONS ON THE EXHAUST SYSTEM
Always make sure that the springs are well hooked to the manifold and in place. In case
of breakage, replace the broken spring. Never race the kart without the 2 springs in
place, as otherwise the exhaust pipe could vibrate beyond control.
Every 10
15 hours, open the exhaust muffler end and make sure that the holes on the
rear cone are not plugged.

CENTRIFUGAL CLUTCH
The engine has a low maintenance dry centrifugal clutch steel on steel. The following
prescriptions, if carefully followed, will allow a long clutch life.
ATTENTION:
When starting the engine, make sure that the brake pedal is fully pressed to avoid
sudden accelerations.
Once the engine is started and kart is still, avoid useless accelerations which can
overheat and deteriorate the clutch, early. Lubrificate the chain before each test,
immediately after each session and check the engine sprocket. Replace if necessary.
A bad alignment between engine and axle sprockets or lack of lubrification will
damage chain and sprocket.
Check the clutch:
Every 5 hours of use.
When metallic noises are heard from the clutch.
If the kart first dragging speed exceeds 4000 RPMs.
Every time the clutch has overheated (presence of smoke or smell of burning).
Clutch rotor and internal part of clutch drum must always be clean and dry.
Please degrease carefully the working surface every time you reassemble the clutch.
Please pay attention when lubrificating the chain, no chain lube must enter the clutch.
To check the clutch, you must remove the clutch cover and the clutch drum.
Replace the clutch
If the body diameter is lower than 83.3mm.
