I thought my H2 was bad at 10mpg...Than I put my 69 back on the road...I'm lucky to get 6. (3.73 at 2600rpm) If I put my foot in it...The gas gauge and the Tach go in sync. The tach goes up..and the gas gauge goes down. My dad, who built my motor for me just laughs. He tells me that I told him I wanted a bad boy..and he gave it to me.
