XS750 '79 left front disc brake clearance issue

[misiek303]

Any idea what is happening with this brake disk and caliper clearance?

I tried another disc spare of a disc, caliper, and caliper mount. I cleaned all the paint where I could, though that the thickness causing it, but no.
It's like 1/16 is moved.
The rest of the brakes are perfect, front right, and rear.

Any washer missing ?

Sorry, can't tell from that pic. I'm guessing non-standard parts perhaps?

Bent fork tube(s) the most likely reason.

I tried also spare fork and entire spare from wheel with its own disks. I have a lot of spares yet, hehe. Same issue, same exactly missing space.

So I enlarged the space between the speed gear and the fork. My finger points it. That helped I have my missing clearance back. But is it really the solution here. Seems kind of odd and silly.

I will check if the other side is bent, and will post results.

Thanks for the info guys! - I appreciate it.

Well, with the slightly wider pic, we can see the type of forks present and they are (perhaps) like a standard XS750D-F and I had posted the calipers for an XS750SF Special. So, I'll play once more:

Sorry. Didn't mean to repost the video.

That was it. Slightly bent tubes. Turning both sides i have equal clearance on both sides. Thanks!
