The original 16″ windscreen has a 21-year-old yellow effect and since I lowered the bike it has been sending air into the middle of my face mask. Noisy.
Also, I’m planning a 6000 mile trip in a few weeks. Time for a new, bigger windshield.
So I bought a 21″ high, clear, widened screen from Clearview, which seems to be the only supplier still offering a big windshield for the classic F650.
Clearview says you need to look over the top of the screen and be able to see an object on the ground 50 feet away. The problem is your windshield angles back and the original is 16″ along this slope, but it’s hard to know where the top of the new windshield will be. My new one curves upward near the top and so reaches higher than I thought it would.
But it went on fine. You leave the protective film on until you decide to keep it. I test rode it and discovered that my head got tossed around at 55 mph and above. Serious buffeting. Dramatically so.
It was looking like I would be sending it back, but I’m not one to give up that easily, especially after experiencing the seductive coziness of a big windshield.
Maybe I could shift the turbulence further back. I tried angling the screen back by effectively moving the two center mounting holes upward by making a 1/4″ x 5/8″ x 1 1/4″ adapter block out of black Nylon 6/6 (one for each hole) that has a flat head screw going into the rubber sleeve/nut in the dash and a tapped hole offset 5/8″ to receive a screw through the windshield. The screen pivoted on the outer two mounting screws, opening up a gap in the center. I also added some spacers on the outer mounts.
I could see over the top of it much better and the buffeting was somewhat improved with some air coming in under the lead edge.
But then I checked online and discovered the need for “lowers”. Baffles near the side of the gas tank near the front. At 55-60 mph I could put my hand right there and the buffeting would go away.
So I fashioned baffles from 1/4″ black acetal and screwed them onto the front fairing. I would have used 1/8″ but I didn’t have enough of that thickness on hand.
The buffeting is gone. What a pleasure doing 55-70 mph in relatively calm air. Still enough air moving through my helmet, though.
I’m definitely keeping the windshield.
Even angled back though, I still had to modify my bike shelter to accommodate the taller screen.
