ok vince,i know you have probably been asked this tooooo many times,but i can't find it in the old post. i need to raise my rr's hp from 8.5 to around 10 to stay somewhat competitive in our new pb rules structure. we don't have enough pb participation to have seperate classes. so now we all run together. from cags to 50cc open whatever. i am only 117 lbs and i think i will be in the hunt with just a little more hp. i haven't seen an open bike show up yet,but this year we are racing at starke fla. for 3 of our races. i am not happy with the idea of driving for 9 hours one way to be lap traffic. any advice is appreciated......russell sr.
