Yep the fxr150 is pretty awesome

Are you plan to us 68mm bore kit? I have a motorcycle with the same engine, I had to change the carburettor to the flat slide. Less maintenance and less things to worry.

The race class we race the fxr's in has a cc limit so the biggest we are allowed to go is +2mm which is a 64mm piston.
