Thanks for the reply !!!!!
I'm not in a racing class, were just racing for fun on my buddy's dirt bike track for cash lol
I just want to build a reliable strong engine! there wont be a governor on it,
yes i was thinking on doing a billet flywheel , valve springs , and decking the head,with copper head gaskets,
could I use the stock retainers, or will they blow apart? and for the push rods I was going to change out the aluminum ones for the steel , or because i'm going to be decking the heads will I need the chrome molly cut to fit ones?
and for a cam what one would you suggest, and from where?
also what do you mean about you putting in briggs single intake valves ? I don't know what that is?
Also i'm having a hard time trying to find a 90 degree gear box do you know where I could look for one, because i'm at a loss lol
Thanks for your help!!!!!!!
