I have an 85,86,&87 xr 600. Just checked fork oil level on the 86. I took out spring, pushed tube all the way up and measured. Topped off so i had 117mm(4.6") from top of tube. Am i to high or to low or good there. Just a trail rider. There was one thick flat washer on top of spring then a 3" spacer with a smaller(2") inside the 3" spacer and two thin washers on top, then the cap. The manual does not show two spacers and only shows one top thin washer. The extra thin washer on top, is that something someone may have added to get a little more spring pressure or do they just put two on top?
