I just came across your post for round head motors I just got mine in the mail yesterday I got mine from simpson motorbikes. Mike is good about answering any questions you might have. I did quite a bit of research on these before deciding in the round head from what I have been told they are better quality castings than the cheapo ones and therefore are more powerful. you do Have to pay a premium, $300.00. Can't wait to get mine in and take it for a spin.
