I'm trying to find a tool to pull the rear shocks apart.
I searched the site first and didn't see anything.
Most of the ones I'm looking at including Pro Moto, assume that you have a split shim in the cap.
I think the BMW units have a screw off eye on the top.
Any suggestions?
The bike only has 15k on it, no shock leaks at all. I just want to clean them up.
Thanks
Michael

I never could get mine apart, and I only wanted to save the springs.

Granted you may wish to retain them for show purposes, but I think we can safely say the shocks are shot by now. Most modern shocks are filled with gas and oil. The gas (nitrogen ?) keeps the oil from foaming, and it works so well the factories put less oil in the shock. In fact, riding the bike splashes oil up on the shaft that lubricates the seals. As the seals dry out in storage, it's harder and harder to retain the gas. I think we can safely say the shocks are useless as far as safe riding is concerned.

Owning an old Airhead is easy.
Keeping an old Airhead running great is the true test.

I doubt this bike will ever be a show bike, but I really like the old shocks.
I think I actually saw seal kits in the fiche for the shocks.
But your right, I put a pair of beautiful chromed shocks from a new Bonneville (only 1/4' longer) that someone gave me, on a 1977 R75/7. It certainly made a difference. and they look great hidden behind the luggage ..
