No i put the UMA 32mm on it, but without the CDI and the carb was not tuned at all since the CDI wasnt in yet. I put about 250-300 km of hard brake in and it "spurted" a lot but still ran very strong and i could tell things weren't up to par yet but was still impressed. Now there are no more "spurts" its just really smooth and really strong pulling. I am 100 KG plus and my fiancee about 42 KG and it pulled us so much stronger like we were in a lower gear all the time. You will find yourself looking at the gauge thinking your in 2nd/3rd but hell your in 4th but the power is still so strong.Do you mean even with the standard carb and CDI the superhead setup is already a mad cow? I am really looking foward to my superhead ^_^
Get it, you will not regret it brother.
