Default Removing Ofna pull start from Hyper 21

Ok.....I need everyones help. I bought a used MBX5 from one of the forum members (thanks for the great deal Revo61!) and I am trying to put it all together. I have an0 Ofna Hyper 21 from an older monster pirate that I am stealing to put in this buggy. This engine is a pull start version and I need to convert it to a bump start version. When I take it apart I have the pull starter, the starter shaft, the back plate with the hole and the turbo fan/one way bearing. Looking at the parts diagrams, it looks like all I need to do is remove these items and replace it with the new back plate. Is this correct? It almost seems too simple. The turbo fan has a peg that goes in the rod end of the crank. Does anything need to go in there?

Also, I am thinking that since the turbofan no longer has to be spun by the engine that this conversion may effect the performance?

Any info would be appreciated.
