Street Twin - Odd Noise?

Hi Folks,

When the ignition is on or the engine is running my Street Twin makes an odd squealy/hissing sound. It's not loud can be heard clearly.

The bike is under warranty so I popped it back to the dealer. They gave it the once over and said that it is a perfectly standard noise coming from the throttle stepper motor and I am good to go.

I am happy with the check (they checked out the ECU etc) but I am curious to know if other folks bikes have the same noise/feature.

I have an audio clip if anyone is really interested!

Thanks

 

I have an MP4 but the forum will not let me upload?

 

Sound cloud!
