My troubles began about a month ago when I had an oil change and decided to try a synthetic by using Mobile 1 20w-50. My whine (which really didn't bother me) turned into a scream. I talked with the service manager and he grudgingly agreed to get me an "I" basket and we both agreed on going back to Dino. The factory tech suggested Yamalube (surprise) 20w-50. When I first drove the bike it seemed to be considerably better-the scream back to a whine and at a different pitch. A 100 miles later the whine is getting louder and so I decide to try Rotella 15w-40 and major difference. I'm beginning to believe it's the oil viscosity and will try 10w-30 at the next oil change (I've had 3 oil changes in the last 200 miles). It may not be just the basket but also viscosity. For the 1st 4000 miles I was using Yamalube 10w-40 and the whine didn't bother me. I had thought my troubles began when I went to synthetic, but I now believe it was because of the change to 20w-50. After I enjoy my bike again for a while, I may try synthetic again but at no higher than 40 weight-I think Amsoil makes a 10w-30. Something to think about!

When I switched to Mobile1 20w-50 synthetic, I went from a whine (never had a chirp) to a scream. Dealer just switched my basket to an "I" and put me back on Yamaha lube 20w-50 (at my request) and I'm back to a gentle whine at a different pitch and almost no whine in 5th. I can actually hear my mufflers now. I had an "F" basket and according to Rick Butler I probably should have tried a "G" basket, but don't want to push my dealer too much. At the next oil change I'll probably go back to 10w-40, but no more synthetic for me.
