Whether planes, trains, motorcycles, or automobiles, Andy has immersed himself in a world driven by internal combustion. Developed for street use, rather than racing, due to it's mild valve spring pressures, its 9:1 compression ratio runs smoothly on regular fuel. Reliefs between the valves and bores are much less pronounced than the old days, only about 0.080-inch deep instead of the old-school 31/416 inch.
