GS1000 air shocks

[Guest]

I found a set of these shocks in great shape and was wondering if anyone knows about them. Can't find anything in search mode and Cliffs manuals don't show these on any 1000's. The GKs have air shocks, but they are a little different.
I removed the valves and drained 200ml of oil, it was dark, but not stinky like most old fork oil I've dealt with.
My question is: how much oil and how much air? The GKs use 14psi, so I think I'll use that as a baseline, then refill with 200ml of 15wt fork oil if nobody has the factory measurements.

You got those off Ebay, right?

Why? Does that affect the air pressure??

Just wondering if they are the ones I was bidding on

These shocks came as OEM equipment on the last GS 1000 version sold in Europe.
I have no information about their maintenance

Not sure about those air shocks, but a lot of oem were Showa, and if those are, 8-15 weight oil is fine, and anywhere from 330-350ml(approx 10.5-11oz for most) max is fine, and don't exceed 25 psi, never use anything other than a hand pump or you'll ruin them.
I have a set of Harley Showa I adapted for my bike, I love them, best ride I've ever had, when you replace the oil, you want to pump them dry, not just hang upside down like you do with forks, install them on the bike upside down, open them up and bounce you suspension up and down to completely drain them, also, make sure you have at least one correctly mounted shock on the other side when doing this.

Here are mine...

Thanks for the info. The seal is labeled KYB, so I'm guessing that's who made these shocks. I've got a no-loss hand pump that works great for the forks. I'll replace the oil, the valve o-ring and the stem, air up the shocks and keep my finger crossed that the seals don't leak.

I knew I should have bid up to $15

Those are interesting shocks, do they have any name or numbers stamped on them?

Other than the seals having KYB 35-47-5, they have 9 5 stamped on the clevis.
