noticed the same thing today on mine at about thirty coasting too. It sounded like it was coming from the front tho. And I did do a full bike wash just two days ago too. Ill go check those harnesses

 

I can't see anything that looks even remotley outta place or misalligned ....or rubbing for that matter. The weather for about the next week or so is looking crappy but 1'st good day I'll get her into the shop and let you all know what they find.
If it ain't 1 thing.....it's another. Thanks for the input.

 

Sounds like the gears. Put it in neutral and coast. If it stops, it is the gears. Try it and letus know.

 

It may be the drive belt is to tight.

 

Well I took her into the shop today and the mechanic take it out for a ride. He loosened the drivebelt and poof......no more noise. (I had a feeling)

Thanks for the input.
