@JetManiac I want to buy your 701 top end kit.. how do I do that? I think I wanna go the biggest bore you offer. I have a girdled head with 35cc domes and a riva red pipe.. and it’s in a WDK x-jet so I guess I wanna make the most power I can get with out going to broke... I still have to tear my engine down But hopefully all I will need is top end. Thanks.
