What is the fork oil amount for a 2002 klx 300 per fork tube

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.
