Yes the motor will fit into the frame, but you are going to need the electronic (compelte harness,cdi,etc) off the motor. You are going to have to modify the gauge cluster harnes and headlight harnes if you are not going to swap those things out.
I would recomend that if your are going to do this motor swap go ahead and swap the gauge cluster and headlight to the 00up ones. It is going to cost a little more but save you a but load of trouble rewireing thing.
