I raced my buddy on his k7 gsxr 1000 yesterday on my 06 r1 both our bikes and 2 down on front and lowered the same. His is all stock other then that and mine has graves full exhuast and power commader mine only pulled 148 on the dyno. I another k7 in town (not my buddys) pulled 160 on the same dyno the same day as I did so we will say he has about 10 hp on me. He is about 30 pounds lighter then me so that should make up for his bike bike being alittle fatter then mine so I would we are about as even as we can get. He was running 1.64 1.65 60ft and I was running 1.60-1.63 60ft he ran a best of 9.63 all day and I ran a best of 9.58. On one pass we raced we had close rt and 60ft we go got hooked up at about 330 mark I had him by a bike or a bike and a half and when we crossed the line we were so close I had to wait on the when light to see who won I did I am not sure how. It was the best time I have ever had at the track that is what this shit is all about.
