Hello, I searched the forum back a couple of years, and did net see this mentioned, when I am on the bike myself, and decelerate, there is not really a chirp, when the wife and I are on, and back off the throttle, there is a chirping sound near the drive belt area. This is the first bike I have had with a belt, all others have had chain or shaft. Thanks in advance for the help guys.

I'd start by checking the belt tension...it may be a little loose with the extra weight of a passenger. Pretty common issue on a belt driven bike. May just need to be tightened a bit. Good luck!

I don't have a belt tension gauge, but it does feel tight, very little play, the chirp is near the front I believe, is there rubber grommets on the drive wheel?
Not sure what you're referring to about "rubber grommets on the drive wheel". If you're sure it's not the belt being too loose under load, I would take the front pulley cover off and just make sure the front pulley nut is tight. This is a well known issue with the Roadstar.

There are 6 rubber bushings (grommets was probably the wrong word...:surprise:) inside the hub of the rear wheel, do these go bad routinely on the RS? Also, how much play should the drive belt have with no load? 1" in the center or less? There has to be a way to check the adjustment without the "yamaha" tool. Also, the pully cover comes off Monday! I will check the nut.Thanks

the 950 came out with a lot belt pulleys misaligned and if the belt was to tight it destroyed the countershaft bearing requiring an engine teardown to repair it, if i were you i'd run the belt a tad looser than recommended. a loose belt may wear a bit quicker but a tight belt destroys hubs and bearings. the pulley misalignment is well know issue on 950s. the only way to fix the misalignment is by shifting the engine or shimming or shaving the front pulley. i'll bet if you look at your rear pulley the belt is to one side not in the middle were it belongs. yamaha knows all about the problem too

No worries...They're called the Cush drive inserts or dampers. Shouldn't be the issue. Here's some good info on the belt. Hope it helps.

OK, bought a tension gauge, tension is correct, I am going to have to check the alignment, but the belt looks right. Also, the main pully nut is tight and the lock washer is bent and touching correctly. Hopefully more updates soon.

Are you checking the tension under the same load when you experience the chirp? If the alignment is off, you want to make sure the belt is tracking straight. It's normal for the belt to run a bit to one side. Good Luck!
