whats the right quantity?

the sticker is ofcourse on jap. Does it translate maybe like :

engine maintenance : 3.6
with filter change : 2.9
without filter : 2.7

??

Thanks :)

HTH

Thanks :)

it does mention "L" next to each figure, I just forgot to write it. I was wondering if my interpretation guess as to what each quantity refers to is correct :) any ideas ?

Just an oil change but keeping the existing filter you will fill it approx 2.7 litres.

An oil and filter change is 2.9 litres

And a full engine re-build it's 3.6 litres.

You should have a dip-stick that'll give you an idea on the level but make sure the bike is sitting upright when measuring it.
