air is hard to push out of the way.

have a look at your dyno chart, your numbers are peak, you may have a dip in the power right at 4300 rpms which is 110 mph in 6th gear.

you may get better results dropping to 5th ( 5000 rpm @110)

try reducing your profile, smaller windscreen, if you have a bunch of "deflectors" on the bike, take them off, remove tour pak etc.

all my bikes are faster than yours- except the Honda 90.

There's a rev limiter. Same effect - but of course in 6th you'd never get to the limit.

I'm not hitting the rev limiter in 5th or 6th. stock windshield and the only wind deflector I have is the one that goes between the forks on the back side of the lower tpiple tree.

Does your buddy have the same exact bike, with the same add ons? Do you both weigh the same?

Sounds like his is tuned more for upper end of rpm range while yours is better at lower rpm. You're probably hitting peak torque lower down in the rpm range than he is. Peak HP may be irrelevant if you can't get to the rpm and vehicle speed due to wind resistance.

Does it feel as if it's starved for fuel? It may be something as simple as your fuel filter needing changed. If you had it on a chassis dyno, did it pull through the 110 MPH barrier? Or did it hit the wall and stop pulling?

huge difference in areodynamics between the batwing and the sharknose fairings. the batwing is like pushing a barn door.
