Hey, I'm looking for a Katana 600 or 750 rear shock to swap into a GS500F.  I'd like one in good condition.  Let me know what you have!

You might be asking a bit much for a like new shock. My suggestion would be to buy a non-leaking unit off of ebay and have it cleaned. Most of the Kat shocks we've been installing come from the wreckers.

Thanks for the heads-up.  I've been riding for a few years but am just now getting into modding the GS500.

Still looking; edited to reflect burning1's advice.

I would buy it and test it, it can be tested by installing on the bike and running down your favorite bumpy road. If you dont see any leaks you're good.
Cool.

Thanks Buddha!
