Does anyone know the appropriate fork oil capacity for an '83(?) GS650L. I know there are submodels, so mine has the air assist and the offset forks with less of the fork lowers below the axle (see pic). the head badge lists it as a GS650GLD, with mfr date 8/82. If it's reallly an '82, it's likely the Z variant based on Partzilla images of the front wheel.
I assume the various fork lowers of the variants result in different amounts of oil required.
The service manual, which covers many sub models, often doesn't list a volume, just a number with no units. Plus, I plan to feed the oil through the air valve after taking out the stem rather than messing with the caps & snap rings, so measuring to the top of the fork won't work.
