I will make a quick update on this bike. Sean and Lucas had it at the track in Ohio again last weekend. They have improved the performance a bunch and I think their top run was 123.8 mph in the mile. This is really impressive for a CX500 that has been converted to fuel injection and turbocharging. If it was my bike I would use a stock 500 turbo gearbox and primary and then go back to a 17 or 18" rear wheel and tire. Lucas, I hope you jump in and tell us what you did to improve the bike's performance.
