Ok got my eye on a deal on a 16 in klockwerks w/vent . But its the goldwing model not the f6b model. Klockwerks said somebody has used "washers and rubber spacers " to get it to work. I did a search but no luck. Any input? I'm 6'1 and will be using an ultimate king so i think the 16in is appropriate. Vent is nice in Oklahoma summer. But is it worth the hassle? Wish they offered the vent on the 16in f6b model.
