Im in the process of building my yfz 501 stroker. The engine is completely put together in the bike just need a couple more things put on to start it up. It is a 06 with +3mm hotrod crank and CP +3mm piston. I had my case machined by JT products for the 07 oil squirter mod. I have not yet put the case on the engine. I have heard there are clearance issues with the piston. Is this true? What can I do about it? Does anyone have a 07 yfz with this big of a displacement or a 04-06 with this mod and can tell me anything. Thanks
