I just found this via the excellent Corpses from Hell blog.
Imagine going a buck-10 on this thing at full tilt around a board track. It brings a tear to my eye just knowing that happened at one point. Really makes the ol’ grapes sag a little bit hearing that amazing engine let loose- can you even handle thinking about what it would be like to see/hear that in person? And 10 or more of them no less! No wonder America was once the most bad-ass country in the world.

Most bad ass-4stroke moped ever.

The bike is amazing. but it's funny my favorite part is the dude has a bump starter / rollers installed in his floor with an down draft exhaust vent to boot. Obvious this guy has a ton of other vintage bikes.
