Hello, I am new to thissite, a friend recomended it to me so I thought that I would check it out. Anyway, I have a pretty much stock '99 XC 700 SP and I recently put a EPI clutch kit on. My problem is that it runs about 8500 RPM. My manual says it should be around 7800-8000 RPM. The weights that came with the kit were 10-62's I put the stock 10-60's back in and it ran about 8200 RPM. I don't know if I should buy a set of 10-58's and try it or if someone has a better idea or info. Any info would be greatly appreciated. Thanks for your time. Happy trails. Jeff
