KX Front Axle Nut Torque Spec?

[RailwayRog]

I bought my USD forks without getting the proper information from the seller so I'm not sure of the year and model it came off of.
Does any one recognize from this photo what they might be from? They are 46mm kyb forks.
The only reason why I'm asking is I'm trying to find out the proper torque spec for the axle nut. I don't think my kdx torque spec would be correct and I don't want to fry my wheel bearings.
One other question regarding removing the axle, the clamp on the other side (throttle side) seems real tight even with the pinch bolts backed off, I have to use a mallet to get the axle to slide thru the clamp, that doesn't seem right to me, all my other bikes I could bang the axle out with my hand.

they are 99-01 forks.
as for the axle, you may find you need to remove the pinch bolts completely to remove it easier.

I have the same forks, 99- 2001 KX like dude said, off a 125 or 250, depending on the spring rate.

The KX service manual says 58 foot pounds for the axle nut.

Okay thanx,
I tried checking the spring rate myself using some method describe on the forum, using a bathroom scale and a pipe with a math formula, didn't work to good for me.
So i have no idea the spring rate, oh well.
