Ok, trucked it home and washed out the oil passages, filter ect. Refilled with oil after it cooled and it will now turn over but not start. Lubed the piston/cylinder and it all turns like normal but will not start although with a tad of throttle it sputters and backfires. Changed plug. No Start.

can you kick it all the way through the compression stroke?
If you can kick it through I'd guess that piston/ring/barrel damage has occoured causing a loss of compression.
If you can't kick it through:
Maybe the lube you put in the bore is also preventing it from starting, instantly fouling the plug. Pull the plug, put it in 3rd gear, hold the throttle wide open and push the bike around the back yard a few times. This will vent the barrel. Refit a new plug and give it another go.

Nope not a fouled plug. Changed it and got the same. I am bummin' thats for sure.
I am really puzzled by the back fire. When I try to start with choke or no choke or hot start then no difference. When I crack the throttle then the back fires.
Hating life at this point.......
Such a dumb mistake......

that way youll make sure the oil is in the head
I drove my previous KTM without a drop of cooling water (unavare) for more than a mile, first heating up the engine and then pulling it on the streets with no damage but sure the oil is the first in line in cooling and lubing

Sounds like you've got a spark.
I'm suspecious of the timing. When the bike seized the timing chain may have slipped. This would account for the back-fire and the not running. If you aren't real mechanically inclined, find someone that is. Get into the engine and check the timing chain.
The engine may turn but with no oil you may have 'burned' some of the bearings.
Your manual is really good on giving you instructions on the engine. Take you time and go over it.
