BumpaD_Z28 Posted February 28, 2007 Report Posted February 28, 2007 contact the piston manufactures and I bet they would make you a set but they would be more $$$ than the 80 overs .... (I'd bet) Quote
bigdaddy69 Posted February 28, 2007 Report Posted February 28, 2007 I've been searching for about 45 minutes since I read your post & no luck anywhere. I would say get on the phone tomorrow and call a few builders, maybe they can help you. Good luck! Quote
Satsol67 Posted February 28, 2007 Report Posted February 28, 2007 Try here http://www.wiseco.com/PDFs/Catalogs/CB07/YamahaATV.pdf .080 over would be 66.25mm I beleive. I know .030 is 64.75 so if i did my math right then 66.25 should be .080 over. Hope this helps. I know its expencive as hell here but if you have no choice. Quote
dajogejr Posted February 28, 2007 Report Posted February 28, 2007 Use the drop down...does all the math for you. http://www.magicracing.com/Wiseco-Piston-K..._p_133-135.html I think for the price you'll pay extra for a .070 set, you'd be better off with .080.... Might be time to be looking for a clean set of OEM cylinders with more life left in 'em... Quote
