Side mounted plate holder?
I just finished my side mount license plate holder for my new SuperGlide. I bought the plate holder from ChromeGlow...the plate frame and chrome back cost me about $35 bucks... I got the one with the LED's on the end, so I could mount it vertical.
To attach it, I made a bracket out of some 2"x2"x1/8" angle I had laying around. I cut a lot of the extra out, sandblasted it and finished it with GunKote..but you could paint it with Krylon just as easy. I chose 2" angle because it's big enough that I could use both the axle and the rear belt guard hole to mount it. It is REAL solid. I'm attaching some pics of it, maybe it will give you some ideas.
I machined the bracket on my mill, which I realize you probably don't have. But you could do the same thing with a bench grinder and a hacksaw. The only problem is boring the 1" hole for the axle... I had to use a boring bar 'cause I didn't have a drill or end mill 1" in diameter. But you could drill a 1/2" hole and grind it out with a die grinder....
The chromeglow frame comes with wires that are about 24 inches long. I added about 3 feet more wire, and then enclosed the whole length of it in heat-shrink wrap. I got 4' lengths of heat shrink wrap at the local Fry's for about $3 each. I used 1" zip-tie anchors (from Home Depot) on the inside of the swingarm to route the cable up to the front, and then tapped into the tail light circuit aft of the connection to the main harness.
You cannot see it in the pictures, but I took a 3" piece of thin aluminum sheet (it was part of the remainder of the bracket to which the inspection sticker is attached), and made a quick cable clamp... I folded it in half around a phillips screw driver, and then drilled a 1/2" hole in the two ends. It is attached to the lower shock bolt inside the swingarm tab, and I fed the wire through this to keep it further away from the rear sprocket. After it passed the sprocket, it goes right back down to the inside of the swingarm using another zip-tie anchor. This may not have been necessary, but it was freaking me out that it was only about 3/16" away from the sprocket.
Grand total, I've got about 43 bucks in it, but I had the angle. You can get the angle at home depot, I think it comes in 4ft lengths, and would probably add another 15 bucks. If you don't have a sandblaster, you're going to have to sand it by hand before painting. Get some sandpaper (the roughest you can find...plain angle isn't really pretty).
If you can find an aluminum angle instead of steel, it would probably work just as well. It would sure be easier to cut the excess away and prepare to finish. Heck, you wouldn't even HAVE to paint it if you didn't want to. But I had the steel already, so that's what I used....
If you look at the picture of the bracket I made (the one mounted on the bike), you can see that the bottom license plate mounting screw comes pretty close to the axle nut. Too close for me to get a socket on the nut. To loosen my axle, I have to use an open end wrench, or remove that screw. I use a wrench, and can still get it loose (and tight enough). But if I were to build another one, I'd move the axle hole and the hole for the rear belt guard up about 1/2", which should allow me just enough room for a 6 pt 1-3/8 socket on the axle nut.
