Not sure if this is the right place for this. I changed my windscreen to the 8 inch on my sg and it helps but, I am trying to fing a pair of goggles that are comfortable and won't make my eyes see quadrouple. Everything I have tried so far shake so bad my vision is real blurry.
Which goggles have you tried? I've used the glasses with foam seal around the eyes and found them to work well with my half helmet. What type of helmet are you wearing? How tall are you? What height windshield did you have before? If all the factors are the same except for the new 8" windshield then of course that's the culprit - maybe it's too short? Or you have to find a different combo to negate the wind.
A combination of factors could be at work to make such noticeable wind effect.
I've been using the Panoptix Raptors for about 3 years and work great. Stay firm on my face and keeps the dust and other debris out. Not cheap, but I really like them.
Same ones I was issued in Iraq...
Ballistic interchageable dark/clear lenses.
Has removeable foam inserts...I prefer to ride with the foam out as they fit my face better that way.
Hey at least I never forget my work "safety glasses"
