Windscreens.
They're the sole bane of the FJR's existence. The stock windscreen, for many of us, is worse, far worse, than no windscreen at all. Why did Yamaha design such an incredible machine, only to cap it off with the most turbulent, ineffective windscreen imaginable?
I have experimented with a number of windscreens now. In addition to forming a personal view of the OEM screen, I have also tried screens from California Scientific; the Yamaha Touring screen; and, now Cee Bailey.
Initially, I viewed the Cal-Sci windscreen very favorably. Compared to the OEM, it had a smoother airflow and was better than stock. After more use, I found it was still simply not good enough. One key gripe I have with the Cal-Sci screens, is that (Lexan, IIRC) the plastic they use has a slight milkiness to it.
My next purchase was the Yamaha Touring screen for the FJR. This was a definite improvement over the other two. +4" height compared to stock, it was narrower than the Cal-Sci. This provided clear improvement in turbulence while remaining narrow enough I didn't bake in warm weather (e.g. anything over 60F).
I found the Touring screen an acceptable alternative--really liked Yamaha's harder crystal-clear plastic)--but still more turbulence than I care for. I liked everything about the Touring screen...save for a 'tad' smoother airflow.
So, this weekend I installed the Cee Bailey I'd just received. It's also at +4 (trying to stay with the Touring screen's height). I will say, I wish I had gone with (for them) a +1 or +1.5" wider screen. It seems a tad narrow at top.
Yesterday was a very windy day as the latest cold front was approaching. A wider screen would've helped a bit more with the strong wind from the sides.
Regardless, I am excited now to do a longer evaluation of this screen. I 'think' I've found my last screen. Going into the wind at 60 MPH, I could comfortably leave my visor open 1/2" and it was pretty calm. On less windy days, it'll be very interesting to see just how effective the screen is. And, given a couple planned Iron Butts this season, looks like stress levels are going to be lower.
Thought I'd share. YMMV.
