i kinda got a noob question

[thenervemann]

okay now when a sprocket is connected to the centrifugal clutch when you let go of the gas the wheels still spin now how does the sprocket not spin i dont get it. i need to see a video of it can someone post one of how it works or explain or something?

the sprocket is connected to the wheel always in a single wheel drive. when you let go of the gas the clutch disengages the motor from the wheel by breaking the connection of the chain and motor

OK,The main part of the clutch,the springs and shoes,when the engine is revved to a certain point,the springs stretch out (centrifugally) and push the "shoes" or "weights" against the outer clutch drum which the sprocket is mounted on.The outer drum spins freely otherwise.

Here is a basic image,some clutches are a bit different but work the same way.

@crazycart, where did you get that image? I wonder if we can use it here permanently.

okay now when one lets go of the gas and is coasting why doesnt the chain keep rotating?

The clutch is 2 peices the sprocket and clutch drum turn when the kart rolls. But the clutch is 1 peices when its engaged.

okay i get it now i think i need someone to post a video of the chain and clutch connected w/ a chain when moving =]

when you press the gas the rpm of the motor speed up thus spinning the shaft faster. centrifical force pulls the shoes in the clutch toward the drum wall, and engaging the clutch. the drum wall is attach to the chain and that is attached to the rear sprocket. the sprocket is bolted to the wheel, so when the sprocket is spun by the rising level of rpm it push's your gokart or mini bike forward. the reason why you sproket keeps turning when your not pressing the gas, is because its bolted to the wheel. = when your moving, your wheel is moving, which means your sprocket and chain and clutch is moving, even when their not engaged. i hope this clears this up.
