I want a centrifugal clutch. Particularly one that's a "sprang" type that will let me still use the manual clutch so I can pedal-start the motor.
I understand the cent clutch from zoombicycles works like this, but they're out of stock. The one from Pirate Cycles is also out of stock. Seems like everyone's out of these.
Boygofast on ebay is selling centrifugal clutches. Will it do what I want and allow me to start my bike without the pull-start?
I am currently running the BGF Cent clutch... there are a few things you should consider before installing. the clutch itself is fine and does allow you to jump start it has the one way needle bearings.
But it will likely break over time and a pull start is almost a necessity. Also you will need some way to extend your pedal cranks.
Most importantly. Ive found from my experience, that the smaller rear engine drive sprockets dont work so well with the clutch, the extra torque/low rpms creates slippage in the clutch and the damn thing shudders when i ride the 36 tooth....
if you have a 44 or 56 tooth sprocket the clutch is much more reliable.
In my case i bought my engine with the clutch pre installed. and had to replace it after the original one broke. you will need a gear/clutch puller tool. make sure to also pick up one of those. and lightly grease the teeth on your freewheel occasionally..... im getting off topic...
if you get the clutch, you will surely end up with the pullstart also. Many of the pullstarts are cheap and break easily. Ive broken two so far. dont get a cheap one. as you will regret it....
and a magneto gasket is a must. dont skip it.
bottom line, if your a newbie, avoid the centrifugal clutch until you feel your up for a challenge. but if you get it all working proper, its a nice setup for a cruiser. not so much for the speed build.
