So finally installed the turn signals on the Full Throttle.
The install didn't go as easy as anticipated, since the rear of the FT is different than the Icon. Instead of having them tucked in, I've had to use the OEM plastic turn signal bracket. The only thing left is the metal bracket this plastic screws to, but it didn't look like there was enough metal to make the second hole to mount them. So if you're looking to do this, you will need to fabricate another piece in order to mount these closer to the brake light. I didn't have time or the luxury of leaving the bike unfinished. Also whoever installed everything on the bike torqued everything to "you're never getting this off" spec.
If you do plan to use the stock plastic piece, you'll need to dremel some of the plastic out of the way, as there is a lip where the OEM bolts go to accommodate the shorter bolts provided. Or you'll need to buy the shorter bolts with same head as the OEM ones.
Alas, the quality of these turn signals are dope. They feel heavy and are seriously bright.
