GS 250 fork oil question

[Gs250Kid]

I'm trying to change the fork oil in my 1980 GS 250 and could not find any information anywhere on how much to put in it. Thanks for any help you can give.

Because this is your first post (and you started a new thread), BassCliff should be along pretty soon with your official mega-welcome. As a free preview, there is a manual for your bike on his site though, and it probably has the stuff you need in there.

Looks like 150cc; unfortunately I don't see a height measurement right off-hand.

Thank you so much! This will be of great help in the future.

140mm is usually a pretty safe fork oil measurement. (Some models use a different measurement -- for example, the 82-83 GS1000E uses 190mm, which matches up with the holes for the air fittings.) You never want the level to be less than 140mm.

This is measured from the top, with the springs out and the forks collapsed all the way. I use a large syringe with a marked tube attached -- just overfill the fork a bit, stick the tube into the fork to the required level and slurp out the excess.

The volume measurement only applies if you're starting with completely dry forks -- not just drained, but disassembled and cleaned thoroughly. If the forks are just drained, a significant but unknown quantity of oil will remain inside. In all cases, measuring the level of the oil is more accurate.

You could put the required amount in, measure the level, and make a note of it for the next time.
