I read the review that the BBr big bore kit really helped the giddyup of a CRF, so I am installing them on my kids crf 100's. I see no follow up tips on rejetting etc. Any advice?
Thanks,
Oh...I am only a fair mechanic. It would be nice if BBR put a hint in the kit as to the direction of the new piston. I found a bulletin on line AFTER I had the motor 95% reassembled...Sigh...at least I found it.
