I have a 1998 ZL500 that is in great shape. It had been taken care of very well over the years. It starts up on first or second pull and everything seems great but I had it in for service and had them look it over and do a leak down test. They are recommending to replace the clutch and...

Looking for reccomendations for piston/cylinder/sleeve kits for a 99ZR low mileage sled I just acquired. Factory vs Wiseco or other brands. Standard bore vs overbore vs big bore. What else should we replace while we have the sled apart. Factory reeds/performance reeds. Anything else I haven't...

I aquired the sled this winter. I rebuilt the top end, I inspected the jugs and they were nice, no gashes or visible marks, and it is said that no honing is required and the rings will seat themselves. Well I have been riding it quite a bit and it has 105 on the pto cyl and 100 on the stator...

I am in the process of rebuilding my top end, but i have a question for all of you that have done this before. I cleaned out all the antifeeze and oil out of the bottom, but now i am wondering how much 2 stroke oil should i put back in the bottom? Or any at all? Any help would be much...
