Rm 80 suzuki 2 stroke transmission/cluth oil

[Bricklinamc]

Hello, i have a suzuki rm 80 2001 and it seems there isnt much oil in my transmission. I haven't filled it up since i bought it a few weeks ago. Should i fill it up with 10w-40 non synt. Or what do u perfer for me to use?

you can get 85/90 at a cycle shop. that converts to a 10w30 auto oil. It really should not be full though. Drain it fully then add whatever the sidecover says. i think its 550mL or 16oz if memory serves.
