1. Put bike on centerstand, put a witness mark on the handlebar at the clamp, place towel on top of bike, unbolt handlebar and move it back/lay it down on towel just behind where it mounts.
2. Loosen the top triple tree fork clamps, and then loosen, but do NOT remove, the top fork caps.
3. Remove the fork caps one by one. The bike will sag forward abruptly with removal of the last, so be ready. The forks are now fully compressed.
4. Remove springs. One side will simply pull out, the other will require compression of the spring to remove the top of the damper rod assembly. Its not difficult, but a second set of hands is almost required. If in doubt, review the procedure for changing springs.
5. Remove the little drain plug bolt at the bottom outside of each fork. The fork oil will drain so have some containers ready.
6. Replace fork drain plugs and tighten, you are now ready to add fresh oil.
7. The manual will specify an oil level measured from the top of the fork tube, with the fork fully compressed. I make a simple gauge with a bit of welding rod, straight wire, etc. Bend a 90* and then measure down and nip off the end at the required length. Now you have a gauge. Add oil until it just touches the tip of that wire. Easy.
8. Reassemble in reverse order.
This is a relatively simple service to perform. Some will insist that the forks need to be removed from the bike, new seals installed, etc. etc. If the fork seals are NOT leaking, don't touch them. The fork bushings will be fine until the seals need replacement, so let it be. Change the oil and go ride.
