How much grease do you put in the grease fitting on a fatboy steering neck?

When greasing the steering neck on a Harley-Davidson Fat Boy, typically just a few pumps of grease from a grease gun are sufficient. It's important not to overfill, as excessive grease can lead to pressure buildup and potential damage. Ensure that the fitting is clean before applying grease, and check for any leaks after greasing. Always refer to the owner's manual for specific recommendations on maintenance.
