Went and looked/rode a 01 WR426 today. Motor seemed to run good, no smoke and felt strong. It did a cluncking noise that would come from the front sprocket area if the motor was down on revs and you can it some gas. Once the revs picked up, it would go away. The guy selling it said it had always done this. The bike has been rode alot it seems, the paint is rubbed off the frame, no decals, could use some new plastic, and chain and sprockets. So what do you all think?? He says he needs 2,700. Should I or should I not buy it?
