i recently bought a 74 cb125, put new chain, removed carb- cleaned out, adjusted idle- idles fine runs well until you put it in gear and try to take off. falls flat on its face and smokes like hell out of the breather tube on top of transmission. this bike was sitting for a while before i bought it. its a pos but just want something to play on. any advise is gratefully appreciated.
