I've found the best thing to set the fork oil level, which is very important to get exact, is a $1 turkey baster. You can also pick up a syringe at your local pharmacy. Just measure out the fork oil level on the side of the turkey baster and mark with a marker. Then insert the turkey baster in the fork tube up to the marker line and suck out the excess oil until its sucking air. The air gap is critical to get right as it functions as a bump stop.
