If I can do both front and rear pieces of angle iron vertical, and spaced right,

I will use a 40t sprocket to start with, and as I go along I might drop to a 36t. For starters I will use a regular exhaust pipe, but I do plan to add an expansion pipe, and if I should feel squirrelly enough....a nitrous kit for an RC motor.

All in all it should be a pretty simple setup. The knockoff uses a centrifugal clutch instead of a standard clutch, so the only cable I will need to run is the throttle. .

So it got me thinking. I saw that Morini-type knockoff in chatbox, and I found the guy's website (I posted that in another it from his site, it's cheaper). All I would need to do is get a clamshell and sprocket from Manic, buy a tensioner, get an exhaust, and make a mount.
ain't even close to a Morini

Your idea ain't gonna work....gearing???

Morinis and Grubee 2 strokes have internal gearing of about 4.1 to 1

20 tooth on the crank and 82 tooth on the big clutch gear = 4.1 to 1

Your pocket bike engine does not have this internal gearing and
runs at full rpm like a Honda GX 50

You need a gearbox or a jack shaft

Did you calculate your gearing?
