Never had this happen on any of my other yammies, but the 08 vector has a groove worn in both clutchs . I would call it fairly deep. I don't drive this one different than my other sleds, and I vary my speed all the time.
There actually are a series of rings or grooves, but the minor ones sanded out of the primary with 120 and then 180 grit sanding while running.But the main one is still visible.
I have run yamaha belts since new.
Anyone else seeing this ?

If it's on the primaries, yes. My '06 Apex did it, and I had to replace both clutch seaves. I chalked it up to getting stuck or getting the belt wet or something?? I did run mine on some water and sunk it once though, so I'm figuring it was definately something I did wrong....

Its the 8DN belts.
They're very HARD and tend to SLIP.
That combined with a very high gear ratio causes the clutch faces to wear at the points where the belt tends to sit -- especially under hard acceleration.

yes ,daughters sled was starting to blow belts. 05 vector . check over revealed grooves in clutch faces. found a good used one, put new weights spring and bushings in it. and it is off to shop to have engine/clutches align as i do not have align tool.

Both my SXr's and both my Attaks had/have that groove in the primary. Never had belt issues on any of the sleds.
13,000 miles on my SXr 700 and was still rotating the original two belts.

I re-face mine every year to avoid having GROOVES and seems to work so far...1st pic w/6500kms with some very minor grooves at the centre but otherwise in good shape and 2nd pic is a perfect condition ready to ride...the killer is when you drive a lot of long steady speeds or always at the same speed the belt always rides in the same spot and tends to groove, another big factor is dirty clutches sheaves,ramps,towers & rollers make sure to keep them nice & clean everything free of dust and other crap, during the riding season clean your sheaves with HOT! soapy water with a SCUFF pad rinse and let dry and keep your belt clean, wash it in HOT soapy water and let dry over night, a dirty belt will tend to SLIP creating a lot of HEAT! I have 10.000kms and still looks like new...
