I have read many topics on this procedure in this forum and am confused. Can a person effectively change the fork oil in a 2002 FLHTC without using a vacumn system on the left fork? Remove the front fairing, ignition lock, and cap. Drain the forks via the drain screw. Pump the forks a few times while holding the front brake, refill in measured amounts from the top for both forks. Thanks for any guidance.
