I have a Klock Werks for my '15 CVORG. I had issues with the shield vibrating and even a bird chirp like noise at idle. Drove me nuts. I talked to the Klock Werks guy at Destination Daytona at Bike Week and he told me that the stock seal is a problem and that they almost always tightened the shield too much. That turned out to be incorrect. I played with it a lot when I returned home and figured out 2 things that I had to address. On the RG, one of the screws on the top(back) of the fairing is a bit too long and bottoms out(or hits something) before actually clamping the shield. And that the shield is only held in place by the 2 screws on each side and there is no outer seal, just space. Also, the KW shield is ever so slightly thinner than the stock shield, making the screw problem more of a problem and the shield a lot more flimsy, especially given it is only held in 2 spots on each side. I took some flat automotive door seal material and fashioned outer seals. This not only took up enough space to alleviate the screw length issue, but also stiffened it up, no more vibration or bird sounds.
I do like the shield. I got the dark one which looks better, and promotes looking out further ahead as you are supposed to be doing. Also, the air outside the envelope is much less turbulent than with the stock shield. I can stick my head up out of the envelope and still get little to no buffeting.
Now, I just have to get brave enough to remove that stupid KW emblem in the middle of the shield. Anyone do that? Does it come off as easy as it looks and without leaving a mess?
