My new Laminar Lip for my 2010 650 Executive was delivered yesterday. I have a Clear-View windshield on my other 650 Burgy but I didn't want to spend another $250 for another one for this bike. The cost of the Lip was $100 including shipping from CA.. Installation of the Lip was very easy with good instructions, and the supplied parts. I installed the Lip so the top was about 2.5" above my windshield. I left the bike sit 24 hours so the adhesive could set up and took the bike out for a ride this morning.
At 40 mph there was no head buffeting at all but lots of good ventilation, at 60 mph no head buffeting but plenty of air over my shoulders, arms and some back-pressure on my back, not uncomfortable at all as a matter of fact it was nice because it was very warm today. At all speeds the Lip directs the airflow up over my helmet where before with the stock windshield the airflow would hit me just above the eyes and the top of my head, even with the stock screen adjusted up the whole way I still got head buffeting. That is gone!

I would recommend the Laminar Lip for those who don't want to spring for a expensive windshield.
Not a very good picture but this is it.
