I guess I lost the 5hp as I did not put the dynojet sticker that came with my power commander, and yes I did order the speedohealer.
i just got back from riding the bike with the 15 tooth sprocket and I love it, I really do not feel any negatives, keep in mind I did not hit the freeway yet but in town it is much better, feels like it should from day one, hit the throttle and the power is there, no more waiting until 4000.
Truthfully the difference is noticable to those of us who own the bike, I felt no ill effect on the clutch or takeoffs as someone had mentioned, I did feel that even if I was in the wrong gear I could get out of trouble. One of my main complaints had been that a time or two I would be pulling up to a red light and by then I was low on the RPM range and still in 2nd and suddenly the light would open, I would hit the throttle and it would not want to go, I would have to take that extra second to drop into 1st, then I would also be really too fast for 1st, all in all it was a pain in the rump. Not any more.
