I hear a gear mesh noise at all times while rolling for the first 5 minutes of riding now that it is cold. I have a 2008 gs sm5. I hear it with the clutch in and out and while I apply the brakes. It stays constant. Once I am warm, it's gone or very very minimal. Thoughts? The noise is more of a transmission sound rather than grinding. Almost like the way a city bus transmission sounds. I can hear it in neutral as well While rolling. It's stops when I quit rolling. I can't hear anything while rolling the bike while it is not running. Only when moving and changes tone with speed. Then it just disappears when warm.
