So you think this is just a flat glass plate, then? The oil level does go up and down if I tip the bike sideways. Just like if it had a full tank of oil. Very strange.

Try 4psi in the back and 5 in the front and experiments from there. Low pressure gauge will give you a better reading than one expected to be accurate at normal pressures.

I have one that only goes to 15psi full gauge. Very accurate.
