Blew my piston I think..

the acitone in the cheap octane boost breaks down synthetic 2 stroke oil even just feel oil between you fingers and add some "boost" it should instantly not feel slippery

Crassius is telling you the straight goods.
1) Plug out, does it turn? If not, pull the side covers and see if the magneto or clutch gear are damaged.
2) if not, remove the intake (2 nuts) and exhaust (2 nuts) and then the 4 head nuts.
3) Pull the head off and have a look. Any damage to the head or cylinder? Does it turn over?
4) Pull the cylinder. The piston may be stuck in the cylinder. Use penetrating oil and ATF to get it free.
5) If the piston slid easily out of the cylinder, check the crank bearings.
Regular fuel, a good 2-stroke oil mixed at 32:1 and NO ADDITIVES will run these motors perfectly.

How do you check the crank bearings?

How do you check the crank bearings?

This guy was looking to see what was seizing his engine.
With the top end off, he would be looking to see if it was the crank or clutch bearings or something jammed in the gear.

In general, to check crank bearings, look for play or any noise or roughness as you rotate them. If you were to pull the engine apart you could look at where the bearing balls run for roughness but I can generally hear and feel it on an assembled engine (cylinder off). On the connecting rod you are looking for any play up and down at top-dead-center. For the pin and wrist bearing look for any wear on the pin or bearing (and rod!) or any discolouration or bluing of any parts.

Happy trails and may you have a beautiful China Girl travel with you for years to come...

So far none of my students have been presidents. Gear heads and soldiers, but no presidents...
