DarylS Posted September 24, 2009 Share Posted September 24, 2009 Hi All, I'm fixing up my old 1978 YZ-80 for my son. It will make a great new-to-him ride just as soon as I get it back into running trim. The fork oil is 31+ years old and I have a sneaky hunch that it probably could use a change. I don't have the service manual so am hoping somebody can advise me on the following: - What is the recommended change procedure? - What's the recommended viscosity fork oil to use? - What's the oil capacity of each fork? The fork seals seem OK, they are not leaking despite their age. TIA for the replies! Daryl Link to comment Share on other sites More sharing options...
