I'm glad I could help...although I can't take full credit. I discovered this problem in another post on TT from 2002! After my bike gave me fits for an entire afternoon and evening, I spent less than an hour researching on TT...problem solved! I've actually been using the resources on TT for a long time...I'm glad I finally joined the fray. On a side note, there's an article in the March '05 issue of DirtBike (106) that shows a great photo of what this problem looks like. Even though the bike in question is a CRF450, the article still shows a very clear picture of a shim sliding to rest against the side of the bucket. Hey, I'm thrilled my first post on TT was a good one...guess I better get back to work now.
