A buddy of mine had this problem. He was having trouble with the kick shaft bolt backing out so he put some locktite on it and cured that problem. But when he needed to replace the clutch and basket, the locktite had ran down the kickshaft and sealed the kickstart leve to the shaft too. It took some doing, but he was able to get it off by laying the bike down and pulling/shaking while someone else pryed against the frame. Just don't get carried away, and be patient. You may also try a little heat just on the kick start lever. If you heat it and then cool
it sometimes they will go ahead and break loose. Just be careful not to damage the oil seal in the case. Hope this helps.
