Hi I recently purchased a 2001 concours. Immediately after purchasing it I drove it home, a distance of 1900km. A little over 1200 miles. It performed flawlessly. However when I start it up there is a diffenite clacking noise. When I rev the engine the noise does not get any worse and seems to lessen as the engine warms up. On the road I cannot hear the noise even when lowering my head. I can hear the engine fine but not the clacking noise. This noise was present when I bought it and has not got any worse. I don't know if this is a normal noise or something to be concerned about. As stated the bike runs really well in all gears and responds to all throttle imputs without hesitation. Any information will be appreciated. I surfed through the post but was unable to find anything similar. If there is please direct me to it. Tks.
