Now that's just hurtful Bobby, my beautiful little 60cc engine neither stinks, smokes (much) or makes more noise than necessary, to perform it's intended function.
Hell, would our pioneering forefathers have been worried by a little noise coming from those huge steam or diesel powered behemoths that allowed us to travel comfortably across our nations in a matter of days, rather than months, because they'd upset our inner calm?
Zen, schmen I say, fugg that, that's for old farts with too much time on their hands, and no friends. I want a Kawasaki H2 750 3 cylinder 2 stroke engine powered rail-snail like Gerheads, with chrome expansion chambers and no damn baffles, towing another rail snail containing several of my mates, and an "Esky" full of cold beer!! (where's a smiley poking out it's tongue when you need it?)
