One for the Kawasaki crowd
I used to drag race one just like that (that's a 750cc by the way) when I was 17 complete with the expansion chambers mind you mine also had bigger carbs. They didn't call those things "widowmakers" for nothing. They had a crazy assed power band (they went nuts from 8000 to 12000 RPM) and if you could keep the front tire on the ground and they'd do the 1/4 mile in stock trim at 11.5 sec.
Here's a stock one and don't kill yourself on that thing. One more thing, they had a nasty habit of going into a high speed wobble at anything over 110 MPH. Have fun.
Before you run it drain the 2 stroke injection oil tank, under the right cover with 750 on it, and put in some fresh 2 stroke oil otherwise you'll sieze her up and I'd ask 3K for it once it's cleaned and polished.
