I have 90,000 miles on this bike (2002 lt). The front disk rattles a lot. I have added several wave washers but it's really loose. I think the main problem is that the metal is worn both on the roll pin and the disk. Which makes it impossible for the roll pin and wave washers to hold the disk stable. But I could sure use some advice. Am I on the right track and is there a fix other than replacing all the roll pins and the disk?
