Motor Oil (10W-30) or whatever you use, goes in the Transmission which is that little screw by the kick starter. 2 Stroke oil goes in the tank under the seat, or if you don't have the tank, you have the block off kit. Which means you have to premix your gas. The gas and oil you premix with oils your crank and piston. Your transmission oil (the 10w-30) oils the transmission and thats it.
Now get out and ride!
