I just finished my R&G tidy install; the tidy itself was fine but the wire cover was a PITA. it's just not big enough to get the wires in with the supplied connectors for the tail light lamps; I spent an hour dicking around with it. The net of it was, for the wire cover I got one screw in, and wound up using zip ties to hold it to the main piece.
The install was not too bad other than that, but the tidy/kit itself had three other flaws:
1. it did not fit correctly when first mounted, as the piece that extends up to hold the plate light contacted the bottom of the fairing, below the tail lights. I was able to bend it back into shape without an issue, but it was off.
2. The holes in the plate mount do not line up with the holes on my plate (RI fwiw). I'd think that license plates have a standard size, so this was weird. I wound up drilling new holes into my plate to get it fitted. Also, there was no mounting gear to attach the plate to the plate holder, which was ok as the ones supplied with the stock piece were reusable.
3. The directions, although direct, were rather brief and could use a little bit of expansion.
I like how it looks on the bike, but I need to take it off and fix the wire cover at some point. I might make some small spacers to give it more room, as the wires just don't fit. Also, I'll use small nuts and bolts as opposed to the supplied screws; one of them stripped the aluminum on the tidy when I was screwing it in (I overtightened it apparently).
