As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

GS1000 air shocks

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.

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.
