Rev'Counter Going Wacko Jacko

[nickodemon]

Been a long time since I had one, but doesn't the needle do the 7k thing while the engine is running as well?

I had the same fault with a fazer i bought recently, but after the ride home it freed off. (rev counter fault code stopped) The bike hadn't been getting used for a few months, so it was just a bit sticky. Its worked fine ever since. Usually its best to strip down, give it a good clean and regrease (coppper grease), rebuild it and adjust the cables.
