After mounting the 18" Jurock, I found I was getting too much updraft buffeting from the large windshield. Then a brother on this site recommended getting a set of lowers from Memphis Shades. They are designed for another brand of bike but fit the R18 forks just right.
If anyone out there reading this is dealing with too much turbulence/buffeting, you will love this mod. Here is a pic and a link to the product that totally changes your riding experience.

Here is the product info:
Deflectors part #: MEM5804
Bracket part #: MEK1980
The mounting brackets very with bike so here is the URL for it:
https://memphisshades.com/products/fork-deflectors-yamaha-xv1900-roadliner
This particular one is for the Yamaha Roadliner, but it is on my R18.
