I'm fairly new here, but I thought I would post some pics of my last project. It started life as an abandoned Bridgestone BS-7/D. A little rotary valve two-stroke 50cc job. This is my second Bridgestone project, having previously built up a 1964 90 Sport. I'll keep the words brief, and let the pics do the talking:
Before. Mostly complete, but several stock parts are in bad shape. My goal was to build up a little cafe racer, without making any real mods to the chassis that couldn't be undone.
Getting torn down:
Bare frame. Typical early/mid 60s tiddler pressed steel frame:
Engine was frozen, but a few days of ATF treatment worked wonders:
Massive combustion chamber:
Frame was cleaned up and quickly primed just so I could play with it for a few months during the build:
As luck would have it, a spare set of Sport 90 front forks fit, in place of the leading link setup which was damaged. I also test fit a Sport 90 fuel tank and fashioned a mockup seat and rear cowl just for eye balling:
Started building a seat and rear cowl. I usually have some 1/4" fiberglass panels laying around the scrap bin at work:
Foam, previous to carving:
After carving, laying up the cloth:
Mockup with tank and seat:
After some color:
Cleaned up the stock wheels, spokes and hubs, installed fresh tires I had from a previous project:
Did a bit of striping and lettering. My first attempt with pin stripe brushes. I give it a solid B- on the result, but I'm sure I'll improve:
I didn't make pics of the engine when I was going through it, but found this shot of the clutch side before any work was done. It was very clean:
Engine installed:
Built a pipe, using calcs from some software I found online. I was really trying to keep it tucked tight to the frame:
Got it wrapped and built a little AL heat shield:
Pretty much "After" shots. I've put about 100 miles on it, and haven't had to fiddle with much. It starts right up, idles great, and keeps the mosquito population down in the neighborhood:
Hope you like it.
I'll try to document my future projects in more of a build style thread. I unfortunately found out about this site after I started.
