    Centrifugal Clutch Fix?

    My clutch bell just detached itself from the small gear cog. It seems as though it was just pressed in, no solder or weld marks on it. If not fixable anybody have any luck on purchasing a decent quality one lately?

    Kick starter ?

    Has anyone ever thought about creating a kick starter for those 2 stroke kits? Like.. putting a pull start system on it and putting a lever on the engine to pull the cable instead of a hand pull system.

    Fuel Ratio

    So I bought a 2 stroke engine from a store and on the ad it said tbe break in ratio is 10:1 but everywhere else I see selling them it says break in is 16:1. Should I just go with their ratio because it's the only place I found with a different ratio.

    Possible changing form 2 stroke to 4 stroke. Questions

    I posted a couple days ago about issues with my 2 stroke set up and some one suggested I consider 4 strokes. I did a little surfing and found that my frame is not large enough (4 stoke needs about 8 & 1/2 by 9 & 1/2 ?) My frame is just short of that. So my only option with this frame is a rear...

The bike already has a 1000w front hub motor that does fine, however, I cannot pedal due to handicap and don't want...
