I'm not sure how much of demand there is for this. I have been porting heads at machine shop I work at for 10 years now. I have decided to take my heads off and port them put cams in bike and put big bore kit in it. Bike has already ran [email protected] I will post my results when I'm done. If anyone is interested I will do a 5 angle valve job and bowl work on heads and ship them back to u for 400. I will post pics of my stuff as I go so u can see work.
