The different variations (S, SM, and E) will all have a similar process, however some of the parts listed above may not be compatible.

    Nice Video, you help me a lot at the Moment because i rebuild my Engine too :) Hope that the Bike runs well now
  • I got an 09with a burned out topend, then got a 22 motor to swap and the 22 has bronze shavings in the oil and a knock, i just want to say thank you for this video, its literally the only one I have found that makes this like it isn't a total nightmare. I decided to part the bike out but if that doesnt go well i may rebuild one or both of the motors.

    You forgot the bolt inside the starter gear. Probably not a big deal.
