I had to lay my bike down yesterday to to keep from running over this four wheeler who had slowed down while climbing a steep hill. And my gear shifter was pushed into my engine case. It looks fixable but I've removed all the Allen head screws and it doesn't seem to want to come off? Can any of you guys give me some advice about this. It seems to have separated from the gasket seal slightly but something isn't letting it slide off for some reason?
