This was on the road, without warning. Suddenly the engine would go up to 3000rpm and stay there. even after engine off and re-start, immediately up to that rpm. First the throttle cable was checked but it looked ok. The bike had to be transported to a workshop and the TB extracted, then the reason became obvious.
A small cable had found its way between the wheel that moves the trottle butterfly valve and the cable. Invisible from outside unless one uses some kind of camera on an elastic gooseneck mount.
