Actually, I owned about 4 different two stroke Harleys when I was a kid, a 1.25 called the Hummer, (2) 165s called STs and a 175 called the Pacer. My first cycle was a 200cc flathead, single cylinder, 3 speed Indian, almost no one knows they even sold one.

XJet, Saitos run just fine on 5% nitro also.
