Sachs starts but rear wheel wont move?

Jeremey Burch /

My g3 has been running fine but i dont have pedals so i have to run start it.

the other day i was in a tight spot and couldnt exactly run full speed to engage the clutch. so i was going a bit slower than usual which i think may have caused my issue. because it happened immediatly after i started it. The bike starts up great but the chain wont pull the back wheel at all. but it revs high like its blasting super fast. im pretty sure this is a clutch issue. im just not sure exactly how to fix it. please help i wanna ride with the bandits this weekend in louisville.

A while ago my clutch came loose, it would start because the starter clutch pushed it back on but it was off the taper. Put it back on and its fine. (edited)

Which piece is the taper? What does it look like

Re: Sachs starts but rear wheel wont move?

Not the same dude, but the tapered part of the crank is kinda like the axle of your crank that tapers down or goes from a larger diameter to a smaller diameter.

See second picture. The taper part is that pole sticking out in the middle.

Re: Sachs starts but rear wheel wont move?

The clutch is on the other side. The tapered shaft is part of the crankshaft.

clutch plates are engaged by 2 wafer washers. yours are probably flattened and not letting the clutch engage the plates.

sometimes I can just take it apart and bend them a LITTLE.

Sometimes you have to clean the plates or groove them.
