I installed a Memphis Shades Batwing on my 1999 1100 Custom. It looks good and has really reduced the buffeting to where it is no problem but there is a whistle at 60+ mph. Not a deal breaker but it bugs me. I am thinking of squeezing some foam type insulation between the headlight rim and fairing as I am thinking that would be the highest possible place where a whistle would come from. Anybody else have this and found a "cure"?
