Warm Tips
Oiling the clutch is extremely important Besides checking the condition of your clutch from time to time, it??s also important to keep it properly oiled. If heat damage occurs, the clutch will never disengage and the machine will start taking off by itself as soon as you start the engine. This is very dangerous! You can see heat damage inside the clutch drum, the metal turns from black to a blue color.
Where do you oil the clutch Behind the snap ring, next to the sprocket teeth at the end of the clutch. There’s an internal bronze bushing behind the snap ring that requires lubrication and it’s up to you to put it there each time.Never oil the large ventilation holes on the drum. This will cause your clutch to not engage properly anymore.
Oil the chain at the same time It’s a good idea to oil the chain at the same time. If the chain gets kinky from lack of oil it should be replaced before it damages the clutch sprocket. A new chain is cheaper than a new clutch.

Note The Centrifugal Clutch 3/4″ needs be oiled before use.Before ordering please check your crankshaft size.Don’t put oil inside the clutch holes: The holes on the drum are to let the hot air out of the clutch. DO NOT SQUIRT OIL IN THESE HOLES. When oil gets in the drum portion of the clutch it will cause excessive slippage, which means undue heat will be generated.

Warm Tips: About the Clutch Slipping:Don’t try and reduce a go-kart speed by limiting the travel of the gas pedal or by putting a restrictor in the carburetor to limit full rpm. Either of these methods will result in the clutch slipping, which is self-destructive. A clutch needs full rpm to lock up as quickly as possible to be able to start to cool down. To slow down a go-kart you would need to purchase a gear reduction unit, which is like training wheels on a go-kart until the driver gets used to how the go-kart handles. A gear reduction unit can reduce the speed of the go-kart in half. About the Clutch Smoke:The clutch weight rpm just isn??t excessive sufficient. The engine not being highly effective sufficient sometimes is the result of a mismatch in ratios to the rear-drive wheels. So the true motive is that the ratio just isn??t steep sufficient, and subsequently, the engine smokes the clutch.The treatment for the primary clutch smoking drawback is to change the driveline in order that the general ratio is steeper. The easy technique is to extend the rear sprocket diameter.So the clutch engagement rpm must be taken under consideration in any other case the clutch will smoke on the secondary jackshaft mounting place.
