blah....whenever i go riding now i am hearing this scratching noise like metal on metal it only lasts like 2 secs. i think it is my chain hitting my guard. Does anyone know the noise it makes when the chain is hittign the guard??? I know it is not the engine cuase i have put it in N and reved it and it didnt make the nosie. Also when i pull in the clutch and just coast it makes the noise.

 

are you sure it isn't merely dust or sand on your rotors or brake pads? If it only appears at the start, it could be that
