Just got my Ivans kit installed and it rocks! The midrange jump is fantasic maybe even on par with my gixxer. I still have to change my ignition timing I had it set to +6. Ivan recomends you set it to +4, I'll probably gain a little top end by retarding it back to 4. I also left the floats at sock level and didnt clip the springs but it rocks the way it is so I don't know if i'll mess with it. I highly recomend it, thanks Rockland Performance.
