A friend of mine has 2000 mach z that is making a thumping sound at 60 mph and up. A few weeks ago while riding he heard a clicking sound that he had not heard before at about 45 mph. Now its a thumping sound only above 60 mph. Any ideas??
Hmmm well I had a clicking sound on my sled awhile ago. Went all the way up north and found out the hard way that it was the rear main idler wheel. IT just kind of shattered off on the trail at some point.
