What are you guys running as far as gearing goes? I was at 14/52 very tough to keep under me. Now running 15/52 and the bike seems to pull all gears longer And it's more predictable on power delivery for me . 85 motor 05 frame. Jetted , on the money Happy with it for now, want to know what the track...

I like the black engine, looks good. What hell are you running on the back, looks like a 52 tooth or maybe it's just the pic that makes it look huge!

I'm having issues with my brothers 85 cr500 It makes spark but not at the correct time I think (you kick it over not even a pop) He purchased the bike non running ( owner told him it ran) The question I have is could anyone tell me the testing sequence to check All the electrics on this motor? Any h...

I just used these collars on my conversion& drilled the case (assembled)
With a 7/8 step drill worked great.the collars are tight and the correct size to fit in the 85 case. I'm installing a 85 motor in a 05 crf250 frame.
