So I did it. I ordered the wings, a 1.5" lift and the deluxe kit (for the tank rear.)
Put it on today. After having watched the videos a few times it went SUPER smooth EXCEPT, it took me a few minutes to realize the wings needed to be mounted with the angle DOWN. I initially had them (on the correct side) so the angle was on top (basically covering the bolt where it's mounted.)
The tank lift kit, front and back, was super simple and right off the bat I'll say that for the 50$ I love the changed look. When the bike is sitting on the side stand, the opposite side REALLY looks noticeably nicer, exposing more of the motor.
Here's a little catch. My RGU came with these;

But after looking at them a bit they really seem to me that they're designed to push the wind up, maybe to flow OVER the rider? But it appears to me they definitely would not let any or much wind continue on to the motor. So I pulled them off and replaced them.
I did go for a little ride, just around the neighborhood so never over 45. I can't tell if the buffeting is different, but at 86 degrees during the ride, if pressed to answer, my legs/crotch did not feel like they were getting as much engine heat.
The rear of the tank (as mentioned in the other posts) does push up into my upper thighs a bit more, but doesn't encroach on my, encroach-ables. I'm sure in time I won't even notice it.
I'll add more info as/if it becomes apparent.

Sorry to resurrect an old thread.... But im thinking about getting the HD wind deflectors for my heritage along with a LRS recurve, so heres my question? these help with wind buffeting but cause engine temps to rise??? I am wondering just how that can be? - if that wind is coming in under the shield and the tank is causing the air to ricochet up into the riders chest thus moving in an upward fashion to cause ones helmet to float or cause head buffeting (easy on this one) then that air was never really helping to cool the engine to begin with - right? or what percent was cooling the engine?
Has there been any wind tunnel study done before and after on this stuff? I get how the wind deflectors would work & the recurve windshield - but under movement I just cant see how the engine would have an increase of 25% in the heat range by using wind deflectors....
Thoughts?
