You were running down the road , (which is hard on a 2 stroke), and it ran out of gas,(which means it also ran out of oil)...how does the compression feel?

i was going extremely slow it was just to get to my friends house but the compression is good

If his gas is fresh and the oil is the same base you use, full syn, semi syn, bean oil etc, your bike should start up ok. Check your plug after you try to start it. It should be wet but not dripping. If it is dripping gas pull your pipe off and see if there is fuel in it. If there is dump it all out and start kicking the bike to get all the fuel out. If it is all dry, I would look at your petcock filter. If you ran it dry you might have pulled dirt or sediment into your petcock screen. Just pull the fuel line and see if you have full flow. You might have sheared the keyway in your rotor. I have a vintage bike that will do that after a couple backfires. The bike will have spark but will be out of time. And as someone else said you might have seized it running it dry.
