First do compression test and a air leak test! oil for the motor or engine?

Motor takes type F tranny fluid or any gear oil that is for wet clutches with no friction modifiers!

IF you premix, Chose a 2-stroke oil that is made for premix, I prefer superM, there is alot of others, If you still have the oil tank and it is injected, make sure you buy 2stroke injection oil! there is a difference!

Plug is NGK- B8ES, BR8ES, B8EG, any of those!

also if anybody knows the size of the nuts that holds the pipe to the head that would help alot my guess is a metric 8 but i dont know the thread

Those are M8X1.25

what is a leak test? and sorry forgot to specify i meant tranny oil. also i think i blocked off the oil injection. i took off the plastic gear to stop it from pumping oil. that should do it right? or do i have to buy one of those little block off things. one other thing im not going to run oil injection so what is the best oil ratio? i always thought 40:1 but idk

Fuel oil 32:1, unless the maker states different.

Make sure that the nipple on the carb that takes the oil cannot suck any air.
