1995 YZ80 help

[nogoodnameleft]

hello, I just got my Yz80 and I need to some things,
1.for the base oil, what should I use? 80w90 ?
2.I am wondering how I'm suppose to check how much oil is in the base, because I do not have a nut to take out and check the overflow.

You NEED a service manual.

Your in Canada Man! If you lived in Arizona, cali, or Nevada that thick of oil would be great mabe, but if you plan on ridding in october to November that oil will work horribly. Use AMSOIL full systhetic 10W30. As for how much oil i cant seem to find anything.
