I just realized that it's been quite a while since my last post, so here's an update.
I played around with the design clay for a while, but found that it requires more of the clay than I had to do anything worthwhile with it. I decided to focus my funds on materials.
The front is finished except for a little filling, and paint. I made a bucket style headlight opening which I can cover with plexiglass later.
For the tail I am going to try the fiberglass over foam technique. I built the shape I want for the tail out of 1/2in polyisocyanurate foam, and am in the process of covering it in one layer of 6oz fiberglass. The polyiso foam can take polyester resin, so that will keep my costs down, and so far it seems to be working quite well.
soon I will need to decide how to make the sides. this bike will retain the original two person seat, so it will be necessary to have pretty long doors. I have a few ideas, one is to use f-glass over foam and hinge the lower portion of the doors to allow my feet to go out. the other is to use nylon with a slot for my feet.
I will have to put in some internal airflow ducting, to pull air away from the engine. it seems to me that having more open space around the cylinder helps it to keep cool, so I am going to use negative pressure ducting behind the engine to accomplish cooling. I will try to take a few pictures of current progress today, and post them tonight.
