GL500's have an air hose between the forks to equalize air pressure. For whatever reason, Honda did not include this on the GL650's.



At least a couple of aftermarket kits have been made over the years to add an interconnecting hose to the GL650.



Here is one that was on a GL650 I purchased some time ago. The fork caps appear to be standard GL650 caps. The hose appears to be from a GL500.



This is the left side. Note the addition of a brass-colored adapter with a Shrader air valve. This appears to be the key unique additional part.

This is the right side.

Does anyone know the history of this particular item?

This setup lookks better than the one I made.

I went to my friendly motorcycle recycler and asked if he had the parts to make one. We pulled out 3 different hoses, not necessarily all Honda, and I made a Y filler/equalizer that has been there for the last 10 years. It cost around $10.00
