I made a guide to disasseble the forks to swap oil/springs after doing it on my xt600e. You just need to take it a bit fuher apart.....Read on
Its not that hard, but a bit time consuming the first time, and tricky without proper tools.
You need to take the fork legs apart as i recall, and you need either an airtool or buy/make a special tool.
This is a guide for replacing the springs, you just need to do the same, and then also remove the unbracobolt in the bottom on the fork (loosen it with airtool before you take the forks apart. Or take them apart and weld a size 32 nut (again, as i recall) to a rod, and put it down the frokleg ho hold "against" the unbraco.
-Put the bike on a stand.
-Remove the speedocable fromt he front wheel.
-Remome the brake by unscrewing to bolts. Twist the caliber back and forward, and remove it by sliding it backwards.
-Loosen the 4 nuts on the lover part of the right leg. After that you can take out youre front axle, do that.
-Loosen the tops of the legs, just loosen them 1/4 of a turn so they will be easier to get of in a few steps, youll probably need to remove you're handlebars. Its 4 bolts, and is real easy.
-Loosen the upper mounts for both the legs, 2 bolts and 2 nuts on each side.
-Now do the same for the lower ones.
-Slide the legs down, they are now off the bike.
- Take the top covers of, remmeber you loosend them before, now theyre easy. If you can, put some weight on them to save the threads a bit.
-When you get them of, you will se the spacer, then a washer, and then the spring. Remove that, and set the leg upside down in a bucket. Pump the leg up and down to get all the oil out, and let it drip of.
Heres where you ned to disasseble more, like mentioned at first
-You're now halfway done, i usualle poor one cup of oil down the legs again, oump the leg up and down a bit, and then turn it upside down, and pump it again,. and let i drip of. Thats just to get all the dirt out.
-Now, compress the leg, and poor oil in it to 16-14cm from the top, depending on how hard you want it. You need 550ish ml to do that.
Just use some 10W fork oil for the job.
-Now its all backwards, remeber to put the new springs in correctly. The end which is tightest together should face up.
It kinda sounds like much, but it isnt. You're jsut remomving the front wheel, taking the legs of, and take the springs out, and change the oil.
Hope you can use it.
