Has anyone done this yet? If so, how much power does it add? Is there anything else you can do to add power to these bikes? (please be technical)

 

My 91 F2 has 104 wheel hp. This was accomplished by putting in 2mil over pistons, 5 angle valve job, porting and polishing the head, degreeing the cams, jetting the carbs, and modifying the airbox. The air box lid was cut above the lip that contains the bolts to clamp the air filter in place. I also am running a fullAkrapovic high mount exhaust system. The engine has been dyno tuned and tested on 2 different dynos. They differed by 1 hp.

Are you looking to do the work yourself or have a shop do it?
