I started working on the tailsection and my initial CAD testing indicated a noticeable improvement in drag reduction with no worse handling from side winds. I went to visit my new motorcycle streamlining guru Alan Smith to show him the work I've done on the front fender, windscreen, tailsection , lowered seat pad and rear wheel enclosure. He recommended I lower my windscreen to shoulder level and contour the side to better direct the airflowcloser to my body. He also recommended I round off the leading edge of the front fender, cover the fork legs and brake calipers, fair in the hand controls, reduce/ reposition the mirrors, reduce/ recontour/repalce the long stalked turn signals.
I wish the Vision was chaindrive instead of shaft drive so that I could gear it up. I'll try a larger rear tire after I wear the current one out.
The sidewind steering interference is noticeable but I'm adjusting to it. I live in a great area for testing as its always windy here in the Livermore Valley. A framemounted fariring would help a lot. I had a 57 MPG tankfill so things are looking up.
all the best L&S
