"The bike is powered by a 500cc Kawasaki three cylinder two cycle motor, mounted in a frame of my (i.e. Gary Walrath) design. The frame has a 2 1/5 inch back bone. This tube also served as the fuel tank. The little baby tank mounted above the carbs is the oil reservoir. Mounting the motor the way I did, made it a part of the frame. A super ridged combination, which is needed at very high speeds.
Yellow Fever was able to set three land speed records at Bonneville Salt Flats."
