In the good old days before the Environmental Protection Agency got going, motorcycling
was in some regards safer. For example; if your carburetor float valve should stick open,
the fuel would go through the overflow tube in your carb’s float bowl and end up on the
ground. Now it goes into your cylinder and ultimately mixes with your oil.
A most dangerous EPA mandate requires that motorcycle gas caps can allow air to enter
the gas tank, but not allow gas fumes to exit. The problem with such a delicate
arrangement is that it requires some very intricate valving in the gas cap to do the job.
