I created the mod to get rid of top speed limit and ignition retard . So I have been dying to prove the only part of the mod that I have not been able to tell you was a 100% fix was the top speed. Today I went to the Indianapolis 500 carb day on bikes with friends. On the way home we had a few open highways to were I had a chance to open it up for maybe 1/2 mile. On 2 different times I was able to bury the needle to its stop which at a guess looks like about 160 or so indicated. Even at that the bike was still increasing in speed . I am used to doing this on a GSXR 1000 AND I GOT TO TELL YOU WITH THE 8% SPEEDO ERROR AND MY BEST GUESS THIS BIKE WILL EASILY GO INTO THE 150 + MPH RANGE . PS BE CAREFULL MY BIKE AT THOSE SPEEDS STARTED SLOWLY WORKING TORWARDS A TANK SLAPPER , If you plan on going up there plant your butt and take both hands and push firmly forward on both grips to lock the steering. If it starts GYRATING ( aircraft term because tires act like a gyro) Don't panic and back out of gas really fast , SLOWLY BACK OUT WHILE PUSHING FORWARD.
