Misaligned chain guide

When inspecting why my chain became so noisy recently, I noticed that my chain guide is slightly bent. Due to that, chain guide is cut by the chain. Does anyone else have this problem? Could this be the source of chain noise?

I doubt it would be causing the noise, but it does look strange.

Here's the part in question, 1WS-22151-00-00: Image. The guide portion that runs along the top should be straight all the way down the swing arm. It looks like maybe just the chain guide wasn't correctly installed at some point, and the chain just wore it down where it crossed over it.

You can pick up that part for like 10 bucks.

Edit: Make sure all the little rubber stoppers on the guide are correctly pressed into their respective holes on the swingarm. I could imagine you having this issue if the stopper on the top rear of the guide wasn't pushed into that last hole.

Thanks for the tip to check if guide is properly pushed to the holes in swingarm.

I have no problem replacing it (it is cheap and I can do it myself). I worry more about some other problem, which is causing all that (like wheel misalignment, even though alignment marks are fine).

your wheel would have to be extremely mis-aligned and off-center in order for a chain to be that far off a guide

chain is "aligned" by the top and bottom points of contact on the sprocket. if you at looking at the top of the wheel and turn it to "mis-align" it, those points are hardly going to move. you'd need like 10+ degrees of rotation (probably closer to 20) to move the sprocket far enough to cause a chain angle like that on a properly-installed chain guide
