I have the RK as well.
The chain has to be a 420. They come longer then needed when using the +2 swingarm so you have to take some links out. After you get the swingarm, just take the other chain off, put that new chain on. Make sure your swingarm is in the all the way back position. You'll see were to cut the new chain for the right size.
