Re: Wind Screens, I installed a Cee Baileys Euro (2.5") higher than 10/11 stock and it does block quite a lot of wind even in the full down. I would like to have a mini one on the bike as well. Problem is that when I do get out for a couple hundred mile ride, at speeds of 80+ the taller wind screen really is nice and the stock one just created more turbulence.
Also re: the heat, it also been a nice surprise since my quest to purchase this bike started with wanting to get on the BMW 1600GT list, which now I'm reading has quite a lot of unhappy owners with that element on the new Bimmers. I'll still likely buy a 1600GT and hopefully this will be an area that the second year models address.
