Hope someone can help?.... I recently bought a 2006 450 although it was running I couldnt ride it as there where parts missing. Replaced the missing parts and took it out only to find it was loosing water into the grearbox, clutch has loads of drag and is very stiff changing gear although they are all there and don't slip. So I've given it a quick top end rebuild, new rings and gaskets etc so thats fixed the water leaking and presurising but the clutch is still dragging and the gears are still stiff. I was thinking it might of been because there's been a lot of water in the gearbox? Also the clutch basket looks fine. Any idea's? I was going to put a few hrs on it see if it gets any better? Thanks!
