• Be sure the oil level is the same in both fork
legs.
• Always use the after market syringe while
adjusting the oil level.
If it isn't used, air may get into the fork.
• If a syringe is not available, first set the oil
level somewhat lower than the normal level,
then add small amounts of oil until the correct
level is obtained, measuring the level each time
oil is added.
