Anything between 30:1 to 50:1, my brother had a 95 yz 250 ran it on 30:1 but that was abit to rich with 2 stroke oil to be honest. I always run just under 50:1 so that it doesn't ruin the plug and the engine performs well. Just becareful not to run it to lean with the oil as it will cause more engine wear and possible a seizure. Enjoy!

44:1 ish sounds in the ballpark. 50:1 sounds too lean.
