My van R on my MKIII 07 is acting strange... Today I was riding my bike and when I look at it I saw that Im on 60% sag So when I got home I took my air pump and pump it up. It was 100psi; I pump it to 130 and try it. Still having 60 % sag I check it with an old rear shok with the same size and find out that the old one is longer. Ive measured the van R and found that its stroke is shorter than what it was when it was new. I took all the air out (and green oil come out of it) and pump it up again. Still getting the same size. What can I do? Is it time for service?... Thanks guys/girls.
