oil?

there s plenty of choices man...yama-lube,10w-30,bellray gear saver,and some others just cant think of them...use the search box
 
In the motor you run 2 stroke oil. In the Transmission/clutch you have to run wet clutch compatible (contains no friction modifiers) oil. I would recommend any weight w40 and under although some of the hardcore drag racing banshee guys run 75w90 gear lube.
 
^ Agreed. I've tried nearly everything under the sun and I like Amsoil Dominator as a premix and Amsoil Severe Gear 75w90 for the crankcase/tranny.
