Just replaced the clutch on my 2012 @ about 17500 miles. Used the EBC street racer kit. Also installed a motion pro quick throttle. Took it out to the track today and the clutch is great, as is the throttle feel, but I can't get over 8500 rpm..... It's not the clutch slipping, it's not revving past and not going anywhere. Every gear its at 8500. Had another guy take it for a spin, same thing. Kinda stumped. Mapping issue maybe? Won't be able to take to the shop till Tuesday so if any one has had a similar problem or ideas on what it could be, let me know.

Cable routing/binding?
In some applications, I've heard the Motion Pro cables are a bit longer than stock - since every gear stops at 8500 RPM, it would seem something is limiting the cable pull/stroke.

Yeah the cables are bit longer, I've looked at nothing catching, it's super smooth.

Are you sure you're using the right cam reel?
Maybe interference somehow with the handlebar switch limiting rotation?

I put the 40 in, but your supposed to be able to use all the reals that come with it, there's no right or wrong, just personal preference.

Take the lid off the box and visually check the movement of the flies to make sure you're getting 100% rotation. Otherwise it could be a tps calibration issue, something that's checked by the diagnostic tool when the cabling is replaced (as per repair manual)

Check that the diaphragms in the throttle bodies are not torn and causing a blockage...

I speak from experience.

I'm pretty sure it's a tps calibration issue, haven't torn it down yet, but every thing is pointing in that direction. Thanks guys for the feedback

Well, turns out tps was a minor issue and the fuel filter was getting clogged. Had the tps recalibrated and while on the dyno discovered the fuel pump was the main issue.
