Unlike a drag race, life is not about the destination, it's about the journey.
I really like the idea of making a thin CF or 'glass cover off the original tank. As for the laxatives, if you got the timing exactly right you'd lose the weight and possibly gain a little thrust off the line..
Zeke said they had some guys come in with aftermarket carbon fiber tanks and they had failures using caswell. However it probably comes down to prep.I used Caswell on a couple of tanks with mixed results. One was a fiberglass tank, done a few years ago and still attached. The other was a plastic tank, the lining in this tank became unstuck after a few months. One thing I did notice with both Caswell jobs was that the lining seemed to have some effect on the first tank of fuel used after the tanks were lined. Both times the engine became hard to start though seemed to run OK once started. Dumping the fuel and replacing it with fresh stuff solved the hard starting.
Be super careful about ensuring sufficient fuel flow - there's no quicker way to stick a piston than restricting the fuel. Big lines are good, use ball valves for gas taps and try to mount the tank high.
Nice little tank. I use a similar one from US Plastics for oil on one of my projects.
Caswell is the only tank liner I will use, but used fiberglass tanks are problematic because the alcohol and oil has penetrated the matrix and that makes it hard for the coating to adhere to the surface. acetone is a good cleaner, but the tank surface also needs to be totally dry and oil free and should be scarified to give the coating a rough surface to adhere to.
BTW, is that a watercooled TSS tank in that other picture?

I think they used a TSS tank on that bike, but I could be wrong. They do look really good.That is the 360 Montjuic Bultaco.

Noisy 2 strokes. Sound like they have a first gear that is way too high for the job in hand.Have you seen this Dutch Yamaha drag bike before? Runs on nitrous.

Neat job, but because the tank is lower than before the pressure (or head) is only about half as much as it was originally, if that. As well, being mounted behind the carb the acceleration forces will reduce the head even further. I wouldn't be comfortable with it and would much prefer to see it mounted higher and further forward.
1 foot head = .43 psi
Have you looked into the handle bar mount auxiliary tanks? Perhaps one of those in the spine of the frame with a faux tank cover over it will do the trick.
