Help identifying a fork component??

Hey folks,
There is a "crossover" line that attaches from one fork tube to the other. Its located right above the lower triple tree clamp. It's a steel 1/8" line thet bolts to two collars on the fork tubes. What is the purpose of this line? I have never seen this setup. Thanks,

Air pressure hose most likely. Do you have air shocks?

[rphillips]

Yeah, earlier GS's required airing each fork seperately, a challange to get the same pressure in both of them. With this set up, the pressure stays the same in each fork, all the time.

OK, that makes sense, but how do you change air pressure? There is no schrader valve that I can see to add or remove air. I have rubber caps on the top of my forks , but all they do is cover the spring prelaod adjuster cams.

If you look to the left side of the forks you should see a valve cap around the fork tubes. It is a chrome cover on my 83
Under there will be the schrader valve. Only pump by a bicycle pump. So I have been told.

You da man Craig. I removed that chrome cap, and there it is, a schrader valve. Thanks,

Just remember if you need to pull the forks that there's a crossover tube between them.
