2017 Honda CB1100EX modifications

[Whoops]

You gents are great. Much appreciate all the info. I'm working on a new plate bracket and will give the washer method a try along with it. I should have some washers laying around that would fit. At least as a test anyway. If not, local hardware shop will have 'em. Fingers-crossed they don't strip as others encountered.

That all said, sourcing the slim cover would be great. Seems like a pricey proposition for something so minimal, but I do think it really cleans up the rear in a way that ties together the overall design. OEM+

Also, it looks like the bolts are different for the shorter cover. Which makes sense, since the longer bolts may already be too long as is (causing the wobbling).

You can see the shorter bolts here:

I too had the wobbling tail light. Found a couple of o-rings in the toolbox and rolled them up the bolt. That's all it took to snug them up and take the wobble/rattle away.
