Bob you make it sound so easy.
First, a long nose on a two wheeler is just as bad if not worse than a trike, Ive been making and riding faired bikes for the past 18 years. I know how to make fiberglass noses, one is on the bike. It just takes time, especially in an unheated garage.
This is my 40 mph bike, the Carp, from 10 years ago. I was afraid of getting around the traffic, I should have went for it. I rode this bike 278 miles in 12 hours. :
If the fairing is shock mounted , like my SWB is, bike then it is less noisy. I rode this last on a tour last spring from Natchez, MS to Chicago loaded with camping gear:
