hi all, can any one help me just built a 2.1 zvh and it runs really hot! i`v had it set up by harvy gibbs and he can`t explane why either!
i`v just notice tho that its got a piper 285 cam but i orderd a 285t2, so the only thing i can think of is that its keeping in the gases yo long!
and does any one know what cam is best for a 2.1 zvh? thanks
