In all fairness to the H2 Kawasaki, you'd have to be dragracing all day to get 20mpg or less. They used to say the tires would be bald within a short time from "all that horsepower". Like I said, I've had a H2 for 31yrs and it will get 40mpg. The main gripes I have is that stupid 5 up shift pattern with neutral at the bottom, and an extremely tall first gear. Really need to slip the clutch to get going. A friend of mine put nearly 50,000 miles on a 73 H2 without a topend rebuild so they are not all that bad. I wouldn't want to ride too far on one, but fun once every summer or two to get it out on the streets.
