No luck. I drained the 10W40, and put some 10W30. I let it run for a while, then drained that again. That should have flushed out whatever oil remained in the oil cooler. Replaced the oil filter, and filled it back up with 10W30. Started the bike, and sure enough after running for 2 to 3 minutes the rattling came back. I also notice that as the bike warms up it seems as the noise is going away, but it actually moves up so lightly just above idle, giving the impression that it's gone. Reving the motor a little to 100 to 200 rpm above idle will reveal that the rattling is still there, but it does go away past that. Frustrating for a new bike I only had for a few weeks. Off to the dealer it goes first thing in the morning.
