FYI: Aftermarket fairings usually need to be drilled before installing
I have used Maier and Air Tech on all my 86/7 GSX-Rs at one point or another. Maier is more consistent. Air Tech molds are getting old, and their fit quality varies immensely from piece to piece. There is a lot of plastic on ebay. If you buy there, make sure the tabs aren't effed up. We use ours for racing, so no biggie. Also, make sure the nut fasteners (on the mids and lowers) are still there. We bought some that was missing the fasteners. It will have to be Dzus-ed to be useable.
You can order the Air Tech stuff from "Backorder" Phillips, uh, I mean Lockhart Phillips.
If you are desparate, '88/9 750 bodywork can be made to fit with some bracket modifications.
