2002 kx 125 fork oil level

The fork oil does not have anything to do with the kind of engine do you have, 2t or 4t. Doesn't matter.
You need to replace the fork oil, you need to know the year of the fork. means, you need to know if it's a bladder or non bladder fork.
oil height of the bladder fork is approx. 70mm, non bladder forks run about 100mm oil level.
oil amount is about 530-600cc per leg

Front fork leg oil level (from the top of the inner tube, with the inner tube fully compressed and without the fork spring) 135 mm

hi, the fork oil level on an 2002-2004 vfr 800 is measured by air gap, with the forks fully compressed with the springs fitted, the air gap between the top of the fork and the oil level should measure 100mm.
hope this helps, paul

Here is a manual for your bike....search for English parts of it.....
http://safemanuals.com/user-guide-instructions-owner-manual/HUSQVARNA/CR%20125-_M

The manual has directions for taking out parts, putting in SAE 5 or SAE 7.5 fork oil, and then measuring the distance from the top of the fork tube to the top of the oil. It should be 3.5 inches. That doesn't sound right, but maybe that is with the forks compressed, the directions may be indicating that. You could judge by the amount you drained out of the forks. Here are the directions in the manual.......
OIL FORK LEVEL
For the regular fork operation,
both legs must be provided with
the necessary oil quantity.
Remove the forkrods from the
fork to check the oil level inside
the forkrods. Work as follows:
- remove the power rod caps;
- remove springs from the stems
letting the oil drop into the
latter;
- bring forks to stroke end;
- check that the level is at
distance “A” below the upper
limit of rods.
(distance A is 3.5 inches)

its 120 mm or 4.7 inches from the top of the fork
Some measure the oil quantity and fill the fork up, some fill the fork up and measure the oil level. The most correct method is to measure the level, I guess, but many guys measure in quantity.. both ways work well.
