im helping a friend shim his belt and for the life of me, i cant get the secondary off at all!!!!!!!!!! i have hit it with a rubber mallet and a 4lb sledge and it wont slide off??? whats the best way to get it off without busting something off? ive never had one stuck like this and to be honest this bike only has 1700 miles on it and is in awesome shape. this is the second 650 brute ive had trouble with the clutches not wanting to come off. the first one was the primary clutch a few years ago and now this one..... any suggestions?
