Found this frame for $5 and I started thinking if it were possible to build with a HF engine. Don't see how to mount a rear wheel.

The scoot original had a GY6 power unit with the engine being unitized with the rear wheel and suspension. These units are excellent clones of the original Honda designs and can be modded with readily available speed parts. All that being said if I were gonna mod it for an HF engine I would simply fab and weld some brackets to accept pillow bearings for a rear axle and wheel. doesn't look too hard. This would make a rigid rear suspension(the simplest way) but maybe a sprung seat could be added. Looks like a blank slate and an interesting project!

VERY INTERESTING Cannonball... Any chance of getting some pictures of what the welding job would look like? I might just go buy the frame today.
 
With out hands on Im just guessing, but two simple either square section or angle iron mounts the size of the selected bearings simply welded to the frame. You would have to figure exactly where to get the axle center lines front to back the same(vertically) and also to allow room for the engine. Looks like a 12" wheel? That could be small enough to drive directly with the right size rear sprocket. You could always drop to the common 10" wheel if necessary.
 
After looking at the frame in the first pic I can see it would require the rear axle to be dropped quite a bit. Would be easy enough to fab a form of swing arm, and use shocks for a rear suspension. Many of the GY6 scoots only use one shock, check for existing mounts. This would give you a rough idea of where the original axle was located. This is not a lot of work to accomplish.
 
Forget the seat! Just make it a stand-up scooter w a 212cc Predator mounted onto the frame.

Where's lowracer!
