1. Nice bike I have a 77, where did you get that seat? It is a lot better than the stock one on mine do you know where to get one?

  2. did you still use the 650crank, so the 750 jugs and pistons fit. any modifing of any thing. because this is what im about to do to mine kz650

  3. The entire bottom end is from the 650. The only difference is the bore. The stroke is the same so all you do is swap out the pistons and juggs. You can even use the 650 cylinder head which will bump compression a bit.
