Just recently my R6 has a really dangerous issue. The idle jumps to 4,000 or even 8,000 revs. Just terrifying when you are entering a corner smoothly braking and wondering why you slow down as expected to a point, then seem to just suddenly run on.

When the engine first starts it seems OK, but after a while this happens. It's not mechanical throttle sticking, although the behaviour is similar. Switching the bike completely off and then on again seems to reset it. If I turn the bike on and just leave it standing, at some point the revs rise all by itself.

Any ideas? This seems like a rare and very dangerous problem, I can't find anyone else reporting this weirdness.

Third gen bikes have both fuel and air controlled by ECU. TPS numbers should increment smoothly with no jitter or gaps; not respond differently to vibration and heat. Could also be the servos that control the airflow throttle plates.

Thanks. Somebody told me it's either the TPS or air getting into the system. I'm slow working on this but I had the airbox completely off and checked all the air hoses in and around the airbox, couldn't find anything wrong. I also now have a way to check the TPS reading, I I am going to ride around, wait for the problem and then check the TPS reading.

But your suggestion that the servos are sticking (open?) sounds also plausible. I guess the only way to check is to replace them.
