For the gear box I like Rock Oil personally and 50/50 is a good mix as mentioned above.

My son's yz 85 takes 5ooml of oil. The thing I can't figure out is how to check the oil level after you've filled it!! I heard there is a screw on the opposite side of the engine that you can loosen and as long as oils flows out of it you're at the right level. Can anyone confirm this and do you have any photos of where this screw is.

for radiator fluid ive always drained the stock stuff and used engine ice, makes the bike run a little cooler if you are riding in sand or just like to keep the revs up.
