What gearing did you have and what kind of motor work? Right now I have a wiseco 12:1, FMF full system, and a UNI and the stock gearing is just running through the gears then bam your in 5th. I'd like to be able to do 70ish once I get some more engine work done. Also where do you guys buy your sprockets? I've been looking in rocky mountain and denniskirk and all they have is 12, 13, 14 front and 36-39 rear.
