Here we go guys, attached are the dyno runs from before and after. The first run is the base run with stock headers and just a yoshi japan can ( no difference in power to standard can), the other line is the difference after a custom map, servo motor removed, full system and timing altered, theres more to come but we are unable to flash this ecu just yet but once we can will make more radicle changed to ignition and secondary butterflies. The bike rides far smoother now and can be ridden in 4th at 20mph with barely any snachy throttle like standard.
Theres a 7bhp gain up top and almost 10bhp in the mid range, as you can see the line is now much smoother. Theres no loss of power any where which shows the exhaust valve is nothing more than a sound/ emissions item unlike early r1s that relied on them to make any power low down.
