This morning I relieved a little tension on the belt - from maybe a quarter to half a bar of movement in the window at the guard, to almost a full section of a bar in that same little window. The difference is dramatic! Up until today, I have had a loud whine at 25-45 mph in 3rd and 4th, probably limited by my poor hearing...I knew it was the belt because the clutch and engine rev's did not seem to be related. After the adjustment, I heard just a note of whine ONLY when I dove into a hard right hand corner. I did not spin the wheel, but did the adjustment with the bike on the ground. Aligning the rotation might ;-) be a good idea, as well.
My Yamaha service tech said, "Yeah, I probably should have done that; it was at the minimum of the spec when you picked it up...As long as you're not into Jack-rabbit, cowboy,(?) hole-shots, you could probably go just a bit softer...."
I did not remove the bags or the pipes, though it would have helped... A little, actually, about a foot and a half, of leverage on a 12-14" wrench sure helped though.
