I have been hearing strange noises from the left side of my '10 RT lately. It sounds like castanets when starting forward at low speeds but can't hear it after 20 or so. There is also a vibration on my footboard. The sound is rhythmic like something is striking the spokes of the wheels or like if somebody puts a coin your in the hubcap of your car.

I jack up all three wheels which showed nothing unusual. With the rear wheel in the air I engage the tranny and no noises. The belt looks normal and looking down the belt line while the tire is spinning shows nothing unusual.

I'm at a loss as to whats going on. I haven't taken the plastic off yet. I will be taking the bike in maybe next week for its oil change but was wondering if anyone has experienced anything like this? Thanks
