Re: B25 trials project.

I have to make a gas tank for my TR25 land speed bike, if I ever get back there (Colorado) to do so. What thickness of aluminum did you use?

And have you found a good source for filler caps?

Here is the rear swing arm I fabricated for my land speed B50, which as you suggest, has a much better supported rear axle than is possible with the flanged type swing arms.

Interesting. Doesn't look very oil tight so you're probably right about the belt, but how does the starter chain and (presumedly, the sprag clutch) get oiled? I'm guessing there must be an outboard bearing to support the starter shaft extension.

I used an A65 pipe on the TR25, as I had opened up the exhaust to 1-1/2". Basically, just cut and reweld.
