Back wheel mis-aligned?

[Mastiff Rider64]

When standing behind my 06 Mastiff I noticed something was off. Or atleast I think it is. It seems my back wheel is not riding evenly, it seems to be riding off to the right of center. What causes this and what fixes this?

Is it centered in the fender? Road crown will sometimes cause these big ass ends to wear oddly.
If the belt tracks true, its also possible your motor and trans could use a re-align? Or you have worn swingarm bushings? Hard to nail it down from a single pic.

Definitely not center of the fender. 3/16 of an inch clearance on belt side, 3/4 inch clearance on brake side.

Search for rear wheel alignment. There are lots of threads about it. It's not that complicated, but for me getting an accurate measurement on the left side is tricky due to the obstacles in the way.

How much clearance do you have between the belt and tire ?

I've had quite a time getting mine aligned. My problem is that getting the belt away from the tire requires it to be a little off track I think. At the back of the tire, I'm also much closer on the belt side.

I think to really fix it we need 2 things. First, a shim to get the pulley further from the tire. Then perhaps slightly offset spacers that move the tire a little bit left from where it is.

Bottom frame rail ~ run a straight edge past the frame. Under the straight edge, what does the level say? Tie the bar so the pull evens the bubble is the frame being level. With a tape measure, the very last tip of the swingarm, measure drop of the other tip of the swing. We twisted?

Take a business card, line it up with the photo here, tilt the card so you see if the tire would ride on the one angle being higher than the other. Or, you follow the card angle to the wear pattern, but the twist is the opposite of the card's angle. If you sort of ying and yang it. Meaning, it could be at the same angle as the card is the twist up on that side, is the yang and ying.
