1985 R80;
I drained out my old fork oil, (no telling when it had last been changed by p/o's)
boy was that stuff nasty looking and smelled bad !
According to the info I received when I bought the bike it has a set of Progressive springs installed.
I was unable to find any "specific fork oil" at a 3w or 5w so I replaced it with ATF.
I added 10 oz in each leg, via the small hex bolts in the top caps on the forks.
The front feels softer and more compliant now, but now I notice a sort of knocking sound over a series of bumps.
I cannot compress the forks all the way with the front brake applied and rocking the bike forward at a stand still , and do not hear the knock , only when i was riding ???
I am also curious about tire pressure ?
Motorcycle is fitted with Pirelli Sport Demons, I have been running 33lbs front and 38lbs rear.
The bike seems to ride a bit hard or harsh to me.
Thanks, Doug
