GL1200 GOLDWINGS

My right fork seal started leaking a while back and has slowly gotten a little worse. I'm thinking of trying to clean the seal with a piece of 35mm film. The seals were replaced 10k miles ago before I bought the bike. Before I rented a storage unit for it I was riding it up and down my crummy dirt road. I'm going to replace the seals later in the fall but I was hoping to buy some time. I was wondering if there was a fairly easy way to add a little oil once I clean the seal. What I have is an 86 Interstate. Any ideas would be appreciated. Thanks, JK.

The only way to add oil safely, I would suggest draining completely and add the correct amount according to a manual.
when your doing the seals maybe check the bushings, if worn they may have contributed to the early demise of the seals
