Name is John B. My 12 year old son and I just finished building an 80cc General bike. We live in Wisconsin and it is 30 degrees here but that did not stop us from firiing it up. We love it. We took turns riding it all day Sunday. I have been riding motorcycles since 1971. I own several bikes. I am selling my 1967 BSA 650 lightning if anyone is interested. We had our first trouble today. The clutch is stuck in the engaged position. Cable is adjusted I think the clutch pads are stuck how do youuu free them?
