i was given a 1981 j440 kawi jetski and was wandering about the maintenance schedule. do i have to change the oil in the crank case like a regular car/dirt bike if so how much and what kind. if you view this message please reply.

 

I have the same problem with a 650, I opened the oil reservoir and don't see any oil?

The previous owner did not add or change oil?

sae 30?

 

2 stroke people no oil to change just add to the tank if its oil injected or mix gas if its a premix style.
