Hi Graham

I bought from probolt for a non NSR (daren't say what bike as Andy will ban me from the site for owning it)
You would need a MC28 owner to respond as I have a MC21. The left side of the fairing all fixed with M6 bolts, (you can use plastic number plate bolts). The screen use any probolt screen kit. They have a spongy surround to the backing nut so when you tighten up it protects the screen. The right side inspection panel ha Dzuz fasteners of varying sizes (well mine are). As a fix I bought some very fine nuts & bolts that went all the way thru the Dzuz with a couple of washers in increasing diameter to secure the fairing. Really difficult and time consuming, but a damn sight cheaper than gen fasteners. Trouble is it then defeats the object of the quick release fasteners on the fairing inspection panel

Sorry but HTH
