This isn't a question, I don't think it qualifies as a technical advancement, but it more than just hanging out in the cafe. Mods, put is wherever.
I did the turn signal relocation on my bike a couple of weeks ago, started with the sax man concept in mind, but my '06 signals mounted different than my '87 ones did, no big deal, I figured it out. But that left an ugly hole in the side rails. I wanted to fill it or cover it somehow, but with what? I didn't want a reflector there, wanted something smooth, not sticking out, had to suit my taste. Yes, my children say I am picky.
So, I got to thinking and looking around and I found out that a 28 gauge shot shell would fit perfectly! I cut the plastic shell off to fit in and put a screw up from the bottom into the plastic to hold it in, just the brass head is showing. I think it looks pretty cool!
