I dont know why you want to make your bike any faster . No ones gonna be able to touch us dune season . O btw , while were talking about the crf I was wondering which paddle , if any , is the best for the Crf. Ive got the brand new intimidator on a warp 9 rim (black i heard that adds 6 hp) and for some reason stevens sandstar gets better grip and not as much sqwrly up the hill.
