I have spent 20 minutes checking and this information doesn't seem to be mentioned online which is odd. I did find the Owner's Manual and that doesn't mention it. There appears to be no service manuals. Contact Honda Service in your country direct. Some go by CCs, some go by distance from the top of the fork leg.
1985 YZ250N, With the Fork off, Cap off, Spring out, take a clear school plastic ruler pore in 5W synthetic fork oil till it's 135mm from the top with the fork tube all the way down, till it just touches the ruler and the 135mm mark. Reinstall the spring, pacer, washer, Damping rod to cap, and install back in the clamps. I raced this bike for 18months in 1985/1986. Change the seals when they leak and toss the 38Kg Fork springs for 41Kg + springs to your riding weight. Over all was a good fork for it's time and Race tech can rebuild the fork and shock to your riding style and you're riding weight. I Miss the Fork flex on hard landings to my other New bikes. I still ride and Race the 85,YZ490 with the same fork.
The best way to fill fork oil is to add the specified amount and let the forks sit overnight to allow all entrained air escape. Leave the fill plugs off. Ofter you let the air escape, plug it up install the forks and add air to the desired pressure if has that option.
no buddy this is just a decal i would go on ebay to purchase the seals alot cheaper than from manufactures make sure you get the dust seals and oil seals

G,Day back.Not sure about how much oil to put in the forks but may be able to help you stop the leak.Get a film negitave from a camera.Like the ones that come in the developed packet.Cut the notched section off the side of it.Trim one end at 45%.Now slide this into the fork seal and with a sawing action,move it all the way around the seal.When you get the feel of it,you will be able to feel bits of dirt in the seal.When you do,pull it out and the dirt will come with it.Do this a few times.This will work if the seal are not cactus and is cheaper than a rebuild.Hope this is of some help.
