Did you or someone else recently services your clutches?
If you did, it's possible that you didn't put it back together properly. There are usually marks (I think an "X") stamped into each sheave that should line up with each other. This is the position that the clutch was balanced at the factory. If you didn't line up the "X"es, it may be out of balance as a result.
It may be possible that extreme heat has caused the sheave to warp as well. You may very well need a new secondary then.
The clutch has never been out uf the sled . It has 2600 miles on it. Not a very good clutch if you have to get a new one every 2600 miles. For the money you pay for a new sled you would think thay would put a good roller secondary on instead the old 1970 butten style :bash:
