Default Re: Pinion Gear Keeps Coming Off

Concur with Bikeguy Joe, get a bigger key and dremmel it down to fit snuggly, bend a screwdriver to assist in installing the sprocket, kind of hold the back of it as the gear is put on, remember the gear must twist to mesh with the clutch pressure plate as it's installed, a bit tricky, if all else failsthe crank has too much runout.
