Hub, bike has 2500 miles on it.
Been noticing for a while now, when start it after sitting overnight (& and its winter time here), there is a metallic clunk in the engine several times whilst warming up. You can feel it knock through the frame. Like something is catching.
Once warmed a bit (say a minute later) it goes away.
Dealer says he hasn't heard of this before.
Any ideas? Doesn't seem like cam chain rattle - which is constant.
