Be sure to check the oil level. Some oil will be left
in the fork tube when the oil is drained and causes
the oil level to be raised slightly.
Be sure the oil level is the same in both fork legs.
If a syringe is not available, first set the oil level
somewhat lower than normal, then add small
amounts of oil until the correct level is obtained,
measuring the level each time oil is added.
