Yes, I've had something like this - like an arc-welder sort of sound - during low-speed manoeuvres. At first I thought it might be the rear brake binding, but can't see any scoring or damage. It has only happened, or at least I have only noticed it, a couple of times so it hadn't registered as urgent, but now you mention it I will try and reproduce it and let you know the results.

OK - I've only heard it a couple of times (I don't get it all the time at 2K RPM, for example); but it could easily be the engine, it's just that 'scraping brake disc' was the only noise that I thought it might be. I won't be out on the bike for a couple of days, but will take it for a test run and see if I can reproduce it and pay attention to the engine area.

EDIT: The VFR forums refer to 'clicking' from a fuelling solenoid under the tank. This may be the source of the noise, although owners who know the engine far better than I do might come along and throw some light on this.
