they come right off but you have to take off the clutch basket and the cam chain. the sprocket slides right off the crank and a new one is 30 bux

so are you talking about the counterbalancer gear or the cam chain sprocket. if its the counterbalancer gear your sol and will have to buy a junker crank on ebay and have a shop swap the gear onto your good crank.
