Thanks everyone for your replies and information. I agree the manual is a bit optimistic about being in 6th at 60 MPH. I can cruise there, but I certainly can't accelerate briskly. Along the same acceleration line, I noticed this bike hates (!) the extremely hot temps we had a few weeks back (110-118 F). That hot, thin air really saps the power. A ride in 80F temps the other day made the bike feel like a completely different animal. I'm hoping the race tuner and some dyno time will richen her up a bit and solve that issue. Anyway, thanks again to all. Ride safe, rubber side down.
