Also there is no balancer shaft, so it can only be tuned vibe wise to one RPM.... not something for a long road haul. I've also put an A65 twin into a Yami frame.... looked way kool, but again... too heavy for the power it produces, etc.

Why waste a great frame on that? I really think a light 500/650 twin is a worthy direction to go in. There is nothing like that in the US, and there is an abundance of top flight singles already made in that range.
I was talking twins. A sweet looking BSA engine would look pretty cool. Some guy did an FZR/BSA sportbike in Australia some time ago.
