hi everyone im having problems with windshields for this bike.i had a memphis shade on it and had a major promblem with buffering.so i got a 20in roadking oem glass and it was right in my eye sight.so i cut it down to a 19 can see great but the buffering is killing me.what do i do go lower to maybe 17 or do i just get a taller glass and look through it.maybe a 21 or a 22.
