    gsxr 750 valvetrain

    13500 rpm on a 58mm stroke, Gives a mean Piston speed of 13.1 m/s. basically the same as a Motogp bike. Most production super bike engines have a mean piston speed of 10 m/s at max rpm. Good luck.

    So some calcs on piston speed. not that the valves will flow enough air to produce power at that rpm.

    13500 on an 1100?

    Need the 750 shock. mount on the 1100 frame is in a different position. iirc.

    Wheel options for 1100L?

    I know someone who recently bought a set of new Dymags which were direct fitment to their 1100l, speedo drive and all. If you want to spend that sort of money.

    Wheels will be good Astralites. But what colour do I do the bodywork?

    Slowly, slowly the dry build begins. It's slow process as just about ever bracket, spacer and mount needs designing and making from scratch. Oil cooler brackets roughed out.
