Not being a hater whatsoever, but something is not jiving with your dyno numbers and your trap speed. Even with 1.6 60’ times (which is pretty darn good), your trap should be about 7-8 mph faster showing those HP numbers. I tune a lot of 1000cc bikes for the track and yes, it takes work to get a gsxr up to the HP levels of a stock S1Krr. But, a 180 wHP gsxr setup like your S1Krr will trap in the low 150s with a 150 lb rider. The shop bike, a ’06 gsxr with only pistons, degree’d stock cams, and sidewinder runs 9.0s all day with a best of email@example.com it makes 184 wHP on VP MR12. Now the answer could be gearing, it’s geared low. The rider is in 6th gear near the rev limiter as she crosses the traps. If we can get her 60’ down, it’s in the low 1.5s now, we maybe able to pull off some 8.9s.
