Any one know of a good engine builder , im lookin to get a spare head for my bike and have it built up just dont know of any good shops in town thanks in advance
Yeah my bike is basically stock , it has a high compression 12-1 piston , cam pipe and what not , but whenever i run just 91 i get a pinging sound on the top end allmost like pre detenation but whenever i run 50/50 91/100 oc it runs fine
wondering what race fuels every one runs ....what kind do u run and why ? i run 76 100 octane but im startin to think this fuel caused all my valve problems so thanks for any one who chimes in
