I had a fairing(big uugly-but oooo so warm) I had fairly short mirrors on the handlebars, full lock turns meant adjusting mirrors, If the mot dude complains about hands hitting the fairing, a cable tie wrapped around the lock stop will sort it Ray
I fitted a Powerbronze Daytona full fairing to my new 650P back in 1995. To mount the upper yoke fastening support, I had to hacksaw the front frame lug off (protrudes on front of the steerer tube). It can put some strain on the cables if you aren't careful in re-routing them. I retained the OEM bar-mounted mirrors, one needed a 2" cranked extension to avoid fouling the fairing on full lock. It came with the fairing fitting kit but would be simple to make a replacement. No problem with hands fouling the fairing on either lock - with or without winter gloves plus overgloves. Hope this helps.
