I have been using Yamaha 2 stroke racing oil. 40-1, same top end for 6 years. Mine wants choke to start but I take it off as soon as I can. Let it idle a bit before driving off. Takes a little bit to get to a temp where it runs clean and strong.

32:1, maybe 40:1, just be sure you jet the carb for your choice and temperature, riding style, humidity, altitude, etc.

Choke on to crank on cold start, then off after it cranks, then let it warm up until the top of the radiator is warm. It takes about 4-5 minutes usually.
