race tech web site lists the oil level in the forks with their springs as 110mm. well what do you measure it with and where do you measure it from. is that measurement from the top of the fork tubes. if it is that are they compressed or extended. is it wiht the springs in or out. as you can see i hate the race tech website and in need of some serious help.
the way I did it (which seems to provide pretty good damping for me) is to fill it up so that the oil level reached the appropriate mark on a measurement from the top of the spring, with it extended as far as it can (the way it is when the spring is in it normally.
I filled to the level recommended on the paperwork that comes with the progressive springs, and 110mm sounds a little high.
I have been happy with the damping on my springs, though (which is what the oil effects the most), and it's been really good handling, so I'd recomend using the setting they suggest.

Speaking as one who has done the progressive suspension spring swap, the measurement is done with the springs out and the forks compressed. Measure the distance from the open top of the fork to the oil level below. I had my bike on the centerstand with the front lifted by a jack under the motor. I then put a block under the front wheel to compress the forks.

Huh? :dunno: I was under the impression the measurement should be done without springs, and with forks compressed. Oh, well, yours work well and so do mine. Next poster please. :?
Methinks Richard is remembering things backwards. :?
As I recall, we did indeed have the springs out and the forks compressed. That's how the Haynes manual describes the process (Chapter 5, Section 7.25 in my '89-'97 edition), and that's the manual that walked us through the process.
eh, a guy's allowed to make a mistake, right?
actually, I was really just checking to see if you were paying attention.
As Kerry and Ed correctly pointed out, it's actually measured from the top, with the springs compressed
Kudos to them for catching my... err....test?
:mrgreen: :mrgreen: :mrgreen:
110mm, from the top of the fork leg, no springs, and compressed all the way :thumb: ........at least thats what i have been able to pick up
