Fork oil on gs850l

[Guest]

Does a 1982 gs850l take the same amount of fork oil as a gs850? 241 ml per fork? Thanks

GLZ fork takes 245 ml according to the factory manual. GZ takes 255 ml.

I haven't looked up the numbers, but I usually start with what the book says, then measure the actual level, as also suggested by the book.

The level for the G is 140 mm (5.5"), the level for the GL is 260 mm (10.2"), although you might have a bit better ride with a higher level on the GL, maybe somewhere between the two levels. That will give you a better progression rate on the air that is trapped in the fork tube. The ride will be even better if you replace the springs with some that are strong enough to not require any additional air. Progressive Suspension components have been looked on favorably, but many of us are switching to Sonic Springs, instead. I have both here, in various bikes and prefer the Sonics.

Steve, is that 260mm level on the GL measured the normal way (springs and spacer removed, forks collapsed, measuring the air gap)? Seems almost like it would be a "fork extended" number. The first gen Kawasaki Concours was like that, due to the holes in the tubes for the air pressure balance tube.
