I Removed the rear wheel from the Scoot this evening, And after doing so I noticed some strange wear on the Driven pulley. Around the outer Parameter of the Pulley the aluminum is chewed up and left the Black dust all over the thing.(Tale Tale Sign of Aluminum being worn "Black Dust"!) So I started looking, Cant find anything wrong. The belt gaurd is clean and new looking, The Belt itself has a little wear in this area. But Very Little !! And I can't imagine it doing this. However it must have been what caused it because it is in contact with it, And nothing else is. In this case the rear wheel must have been Miss aligned from the factory, Because it has not been off.. Anyway here are the pics ::

Here is what the belt looks like. After seeing it under the lights I think something got in there and went through the belt/Pulley ??

The Single contact patch in the middle is just where I rolled it off the pulley!! Thats why it moves from one side to the other, From when I rolled it off the Pulley....

Anyway,,,,, What do ya Think ??

Looks alot like mine does cept mine is worse. But then again my bike is an 02. I just noticed it this past weekend while cleaning (it's been a month. It was due) I'd bet it was the belt that did the damage though. Aluminum is really soft even compared to rubber. I have seen rubber mud-flaps rub holes in aluminum fuel tanks on semi-trucks. I'd never believed it if I hadn't seen it with my own eyes

Missaligned wheel? Misshaped belt? Those are my guesses but I'm leaning more for the wheel alignment.

We were at the HD (on Eastern and Sahara as we have 3 total in town that sell bikes) Saturday. They only have half the bike that they had 2 weeks ago. Vegas turns over more bikes per month than most do all year. I don't know why either but a lot of people fly to Vegas and ride home.

From website: Their dealership located at 2605 S. Eastern Avenue is the world's largest dealership in physical size.

I wonder how that is measured. They do have a massive shop, useless but massive. They also have a huge rental business for obvious reasons.

Glad you had fun, sorry about the heat. Hope you took advantage of the Strat and got on a ride or two.

I can't see anything but normal wear. But I have only experience with my bike's belt. Is one side of the belt worn more than the other? How many miles on belt and pulley?

4000 miles... And the belt doesn't look worn at all.. Just the pulley shows some chewed up edges on one side !
I will check the alignment when I put the rear wheel back on this eve.

Well I got it back on but didn't get to ride any, I want to check the alignment before I tighten the axle nut down to specs, And ran out of time.
The Metzeler 160 is going to clear everything just fine, And it looks Great as well. Can't wait to try it in the twisty's !! Then on to the front tire next !!

Sporty drive belts always favor the outside of the pully, hence the chewed up edges on one side, although yours maybe excessive
i dunno cause mine shows no wear even after 6.5 yrs with the same drive belt.

Only thing I see that is concerning is the white spots on the belt teeth in the one area. May have caught a stone recently and you may just be seeing the after effects of that one incident. The pulley teeth have round edges and yours looks just fine.....:geek:geek:geek
