On the rear wheel it appears that you don't have it equally pulled back...there are lines on the axle blocks...they should be equal.or in other words if your three lines back on the left you should be three lines back on the right.they are there for you to index the rear wheel equally...they are on the top and bottom of the axle blocks

It's important to read the axle blocks from back to front when you're using them to align the rear wheel. The left side block is missing a mark at the front because of the ledge on the front side of the block that's to keep the axle from rotating as it is tightened. If you count from the front, you'll be off.

Besides simply running the tire and chain into each other, a misaligned rear wheel can cause the chain to "snake" horizontally under deceleration or very light loads, coming into contact with the frame or the tire, depending. Naturally, it follows that a chain that has a good amount of wear in the bushings will be even more prone to this, so that's also a consideration.

This is a very accurate, yet cheap, way to get the basic alignment set:

Align your rear wheel axle to the swing arm pivot.
The block marks are known to be out by 2mm or more.

This will happen on those tires and wheels. You can redish the wheel and it will help. I have a 160 and rubbed a lot till i redished the wheel. Tried a 150 and it still rubbed. Some guys use roller or rubbing block to stop it. You can also run a non oring chain too. But mine looks like that and now no more rubbing.

I'm not sure about the wheel, but it looks like you have a lot of coolant in your overflow tank. :rolleyes:
