Mine sat on the shelf for months and months after I first bought it and did a test fit (then got on the Interdweeb and found all the negative comments about it).
I did look at the idea of adding something underneath it to stiffen it (like aluminum plate or bars, or fiberglass, or whatever). However, at each step, I said to myself, "Keep it simple, Stupid! I think despite that it's a little more complex than I would've liked, especially with respect to the number of fasteners. But it works, I think.
As for the "half chain guard cover", I may yet cut that back. Ideas are either minimal cutting (just follow the line of the OEM guard) or radical (cut off the rear part as far forward as possible, and trim the bottom towards the front). Dunno yet.
If I was a manufacturer, I would either go the Harris way, or make a minimal one from the same material as the chainguard (polypropylene?) similar to the ones fitted to the more recent models of CBR1000RR. They may not look as swish as CF, but they're rugged and sufficiently flexible that anything that the tire picks up and tries to wedge in between itself and the guard shouldn't damage anything.
Oh - and if anyone wants details of the el cheapo but very effective rubber flap
that preceded this fitting, let me know.
Ar you kidding? Post it up. All mods are welcome LOL. Did the same to my front, after cutting it down, on the sides.
