O-RING (4X7)

The tappet cover can get away with the re-use of the old 'O' ring, but sooner or later it will start to allow a fine mist of oil in this area spoiling those handsome V-twin aesthetics! It is always advisable to replace this 'O' ring whenever you have cause to remove and replace the tappet covers.

• It is worth replacing these 'O' rings every year as the old items can degrade with constant temperature change
