...again, in high school: I had a Harley Hummer: 150 cc 2 cycle and 2.5 horse power max, with the muffler/chamber attached. Add the chrome extention from your mother's vaccum cleaner, destroying back pressure and reducing net horsepower. When i first rode my Triumph 21 (350cc two cylinder 4 stroke) from just getting off the hHummer, I thought I was riding a spaceship!
