As you ride off then any little stones under your wheel will sometimes stick to the surface of the tyre and get rubbed off by the mudguard. could just be that buddy as the mudguard does look pretty close.

Ye could be Chris.....my only other thought is that maybe it isnt even a ping.....could it be like an electrical arcing noise that just sounds like a plastic ping but again theres no reason that wouldnt keep happening once i was going faster......or would the connnection into the back of the speedo make a noise like this if it was foccing up?????
