I haven't posted any updates in a while. After getting the new Vetter fiberglass nose mounted I could see that my tail section was too tall so I modified the existing framework to lower it about 3 inches. I also reskinned it with doorskin ( thin wood veneer) rather than coroplast. I ran it in the our recent SF BAy Area Earth Day fuel economy challenge and finished second after Alan Smith; he got 95 mpg and I got 86mpg.
I acquired another 250 Ninja( 2005 model) by trading my 1982 Vision for it. I've been working on it and will test it to see if it will be a better runner than the current 1999 model.
