Due to a thread I read about "no replacement for displacement" I went fishing and found this. Too bad the largest single cylinder engine won't fit on on a bike. You want displacement! Screw 66cc, why not 20,175ci ?!

Have a good one!
 
That's wild too, but that 20,000ci single could crush that 4,200cc Kawi... literally suck it into the intake, crush it and spit out along with half an exhaust valve... :)

:p

4200 cc = 256 ci

20,175 ci = 330,609 cc

But I have to admit, at least you can still drive the Kawi around. The 20k would have to go in a recommissioned battleship, or aircraft carrier, or Cadillac... heh heh

Thanks for the replies guys
 
You sure thats not a 4 stroke. I tawt I taw a cam in tder? It also sounded like the bass line for a music vidio....I started tapping my foot to the "music". I love motors.
 
Dayam, that's a beast Joe, wow! Yea I still have enough left to rattle, they're in a jar across the room.

Yea Goatman, there should be a "He doesn't light them up :(" warning on the vid, heh heh
