i fitted the Nippy Normans to my '05 GS, and they are fine, not sure why you say the BM ones are better ?
I do however think that they may cause a little bit of aerodynamic uplift at v high speeds.
Worth the money IMHO.
and full details of materials used, time of heating, precise angles of curves, degrees of leading and trailing edges, QUOTE]
I agree.
Unfortunately don't think I can post pics as I'm not a proper tosser. As far as full details go it's more Blue Peter than aerospace engineering and simply make it up you go, something like this..
Make a template for the winglets out of a bit of cardboard and try it on the bike making sure that the screen can still move over its full range of adjustment without fouling.
Aquire some Perpex (Plexiglass in US) I used 8mm which worked well and doesn't flex and use a hacksaw to cut it to the same shape as the cardboard. Don't mistake other clear plastics for Perspex, they are not the same and may not bend when hot. File, sand and if you are bothered, polish the cut edges with something like a metal polish until nice and clear. The second winglet is a reverse of the first so you can use the same template.
Be nice to the missus as she'll be vital in a min'.
Bung one winglet in the oven at 150'C. Put it on a sheet of aluminium foil on a flat oven tray. Keep a constant eye on it as if the edges get too hot they will start to bubble. Use an oven glove test to see if it's becoming flexible, it's HOT so take care. As soon as it feels like slightly bendy toffee pull it out and leg it to the bike and lay it in position on the bike allowing it to take up the same shape as the fairing just ahead of the tank. It's worth studying pictures of 'official' winglets that other tossers have posted as this gives an idea of the mounting position and shape you are aiming for. Bend the rear edge down a bit to deflect air in the general direction of the cylinder head.
Now then, this is where the missus is vital. You need a helper to sprinkle cold water on the plastic so it sets in the shape you are desperately trying to maintain. Once this has been done you can feel smug as the only remaining step is to use some serious velcro (Halfords) to attach it to the bike. The advantage is that no drilling is necessary and it leaves a bit of room for adjustment though I've no idea how easy it will be to unstick the glue should that ever become necessary.
All that's left is to reassure missus that the next casserole won't taste of plastic. Job done.
