Yes the Uber scoot has the heavily restricted California emissions 2-stroke

It takes quite a bit of grinding to remove the restrictor holes on the block then grind the skirt of the cylinder to match the block

For a direct bolt on replacement you will have to contact the manufacturer for a new cylinder

Fortunately the Piston ported pocket bike engine is a direct swap if you do end up swapping it the unrestricted engine has a lot more power and you will have to lock it in second gear or risk stripping out the transmission.
