hi,replacing the seal is quite easy,although it will sound complicated,jack up or lift the bike off the ground so that the front wheel is in the air(about 12-14 inches should be enough,remove the front wheel from the bike,remove each fork leg,this is done by undoing the bolts(4 on each leg)the front fork is quite easy to work on just do one at a time,remove the dust cover from the top of the staunchion tube(larger diameter tube),beneath that dust cover you should see a retaining clip that holds the seal in place,remove the retaining clip(and dont lose it),the seal is now ready to remove,the easiest way that i know to do this is to force a screwdriver through the body of the seal,you may need to hit the screwdriver with a hammer as some seal have a tin backing plate,put a hole through the seal on each side of the fork leg taking care not to damage the chrome of the fork leg,then use the screwdriver to lever the seal out of the fork leg,to reinstall the new seal,put a smear of grease or oil around the outside of the new seal,slide the new seal down the fork leg and seat it squarely into the fork tube,very carefully tap the new seal into place being very carefull not to damage the outer surface,i use a small piece of dowell type timber to do this as the wood doesnt damage the seal surface,i use a small ballpeen hammer to tap the wooden dowell,once you have the seal seated down the tube you should be able to see the groove for the retaining clip,reinstall the retaining clip making sure it is seated corectly,replace the dust cover,if you are going to replce the fork oil or top it up do this once the fork leg is back in the bike,repeat the whole procedure for the other fork leg,once you have done the fork seals reinslall the fork legs back into the bike and refit the front wheel,to top up the oil in each leg,simply undo the large cap on the end of the fork leg,you may have to remove the handlebars to do this,be carefull as the cap will be spring loaded and can easily fly off if you are not ready for it,top up or fill with the correct weight oil for your bike(normally a 10w oil),check with your local honda agent for the correct quantity,normally between 400-500 mls,this all sounds quite complicated but is actually quite easy and can be done with a minimal of tools,each fork shold take about 1/2 hr to do...hope this is a help to you

SOURCE: what is the fork oil amount for a 2002 klx 300 per

The owners manual says to do the following if you don't want to remove the forks:
*raise the front wheel
*remove the fender, meter cable & unit, headlight, handle bar, fork protectors
*loosen the fork upper clamp bolts
*remove the caps from the top of the fork tube
*fully compress the fork tube so the dust cover touches the bottom and place a stand to hold it
*remove the springs
*set the oil level 68mm (standard) or 60 - 90 mm (adjustable) from the top of the tube

It may be easier to remove the tubes and you could replace the leaky seal at the same time. I did this recently and put in new springs too. It was my first time working on forks. With help from TT members and the service manual it was fairly easy. I didn't buy an oil gauge, seal driver, or spring holder. I used a ruler to measure the oil and a medicine dropper to remove any excess. For a seal driver I used a piece of PVC pipe cut in half then secured around the lower tube to drive the seal. Try a search on replacing fork seals for more info. 5w oil is standard but i have heard that 7 works well Good luck.

let the oil drain right out of each fork leg first put back the plugs and tip in 128ml +/- 2.5ml or if you wont it in old money! its 3fl ozs,app in each leg down through the top bolt hole on the leg, use only the right oil bont just tip in any old oil or the forks will get very stiff and hard to move
