I bought an 03 cr250 and it makes weird noises, about 1/4 to 1/3 maybe 1/2 throttle it makes this really strange rattle, checked to powervalve cables, rebuilt the top end, don't really know where to for from here. Any knowledge helps! Thanks

clutch lever slop?


Don’t piss off the old people - the older they get the less “life in prison” is a deterrent for them!
