Simple front streamlining, like even a frame mounted front fairing, won't do as much as just adjusting your crouch. I put a Norton Dunstall type of front fairing on the Bridgestone last year and only gained 1-1/2 mph (from 113 to 114.5 mph). If you want to try partial streamlining, there are a bunch of things that I can suggest, but they involve completely changing your bike into a full blown race bike.
So keep it simple and remember to keep everything tucked in and get as low as you can on the bike and have fun!
