Supercharged 1972 cb750, bored to 900cc find
« on: September 27, 2008, 09:29:51 PM »
Crazy folks in Aussieland, I'd bet this would give the new high tech 'busa fans a run for their money.  And this bike is ragged and ugly as hell, to boot.  The last thing I'd ever expect to go real fast- if it weren't for that S/C.

At least it's not one of those killer 1080's, eh?!  ;)  Wish there was more info.

Nitromethane is a very powerful fuel, I bet it is scary fast if it doesn't lift the head right off. I can't imagine it living very long if it's got stock bottom end pieces.

I'll be the first to say that is a POS. I can put a Garret on my John Deere ( I don't know about superchargering it). I hate backass projects.....especially when I'm so busy with worthwhile ones. ;) To much free time on their hands. ::)
