I have a honda cbr 600 f3 which I have recently changed the consol on. After changing the consol, it suddenly sputters at 5000 rpm in any gear. What could be the problem?
Checked but found out that the air solenoid was already removedOn the F3, there's a solenoid controlled air valve that runs off the cluster. Likely your issue. (It is supposed to be open or closed differing amounts depending on speed, engine RPM)
Further reading shows several people reporting a "giant flat spot at 5000 RPM" with their F3's which sounds on-target.
CBR 600F3 - (FIXED) Flat spot at 5k rpm - My bike has been giving me hell, with no power at about 5k RPM. Didn't matter what gear, although in 1st it would occur later in the rpms. At about 5k rpm it'd sometime act like it was stalling, dropping speed till I downshifted or jerking back up to...cbrforum.com
This should see you right.
