Tonight I installed a new 15" Madstad windscreen. As mentioned here earlier, those rubber well nuts don't work for attaching the metal bracket. Big washers and nylon lock nuts on the same screws, however, did the trick. The bracket was not the best fit, but I eventually worked it into place and it is solid. Yes. Makes a huge difference in air pressure on the body. It took a little adjusting but 60 degree slant at about nose level worked the best for clean air at helmet level. Air temps in the high 80's and it was clearly hotter than with the short screen...but not unbearable. Now I know that the front mirror covers don't "pop off" by pushing them forward. You pull them sideways. Duh. I am finally making peace with the CTX plastic pieces. The instructions that came with Madstad screen gave a pretty good narrative on removing plastic. However, the instructions lacked some very basic stuff like the proper orientation of the adjuster units. Luckily someone posted a picture of their bike here and I was able to use that as guide. Planning a big trip this weekend so that will be the test.
