Hi Guys,

For some reason, my AP1 S2k seems to be making a helicopter like noise which can be heard when maintaining a low speed or lightly accelerating. It seems to go away if I press the clutch and free wheel. It is also not there if I just rev the engine in neutral so I'm thinking it's clutch/gearbox related. I also get a loud buzz if I accelerate then pull my foot off the pedal. Are there noises anything to be worried about?

You can hear the helicopter noise along side the engine noise in the video below. The buzz can be heard at 0:33.

Edit: I've just read the FAQ and now know the buzz is clutch buzz and nothing to worry about. I'm still stumped by the helicopter noise though.

Any advise would be greatly appreciated.

Thanks
