gear oil level on '93 YZ 80

[bob11]

Does anyone know if there is an oil level port (bolt?) on this machine? I can't seem to find one like is normally on most bikes.
I just got it for my son, drained the gear oil, and refilled it with 500cc like it says on the side case. But no way to check level?
I'm thinking, am I just missing it?

On our 96 YZ80 there is no inspection glass or bolt to remove to check the level. Probably the same on yours.

For a few bucks you can get a generic (Clymer/Chilton) bike manual. These provide decent instructions for most repairs.
