Buffeting gone!
« on: June 08, 2013, 01:09:25 pm »
After researching the topic here and elsewhere I finally replaced my stock Connie wind shield with one I made. The stock one was both an eye sore and made riding at speeds over 50 mph way too uncomfortable. Total cost came to $26 plus about 5 hours labour.  I used 1/8" polycarbonate, a router to cut out the shape followed by a drum sander to smooth the edges. Very happy with the results.

How did you determine how long to make the new one to eliminate the buffeting?

I made it so the top of the shield sits just below eye level when sitting normally on the bike.  However I think a major cause of the buffeting on the stock shield is the reverse lip at the top and the curved shape of the entire shield.

 I have a friend with a C10, makes own shields, and he also found the stock lip contributed to the buffetting

I used 3mm Makrolon (Bayer) which is actually a little under 1/8".  Maybe this brand of pc is stiffer than Lexan? Anything thicker and it would have been very difficult to bend the screen to attach the windscreen screws. Once attached it feels very stiff and solid - up to 80 mph so far.

Nice job. Sort of like a Rifle shield. A Rifle shield is straight with no "flip" either and it doesn't buffet if it's high enough. I like the side tapers on yours.

Thanks... mine is 22" high from the base...works great.

Did you warm/heat your new custom shield in any fashion and form it prior to mounting, or did you mount the flat PC cold on the fairing one fastener at a time?

I mounted it cold one fastener at a time. You can fold pc 180 degrees back on itself and it won't crack. What's critical is the holes for the fasteners have to be perfectly aligned. I used a strip of card stock taped to the bottom of the oem shield as a template to get the shape and hole alignment.
