I have an undercut race transmission with GYTR gears from R&D Motorsports in Florida. It is the transmission I had in my 05 Factory Yamaha Race bike. It came out of Jamie Hackings bike. When I took the motor apart I sent the trans out for a rebuild and undercut and never got to using it. It cost me just under $800 and that was at dealer cost. Asking $400. It is in the box wrapped up as it was sent back to me. Send me a message or post up if your are serious. I will take it out of the box and snap some pictures and post them up or send them to you.
