For pushrod adjustment five speed Sportster and Buell engines require that you remove the cylinder heads and take off the one-piece pushrod covers to get to the pushrods. This is a very complicated way of pushrod adjustments for tuning or maintenance when adjustable pushrods have been installed. This Zipper's pushrod cover conversion kit permits access to the pushrods using adapters that allow the use of earlier style telescoping pushrod covers. Kits for 1991-2003 5 Speed Sportster and Buell engines contain two Siamese style billet aluminum bases and special seals for the front and rear cylinders that replace the OEM pushrod tube lower retainers. Kits for 2004 to present Sportster, XR 1200 and air cooled Buell engines work with the OEM lifter bases. All kits include full telescoping stock length chrome plated pushrod covers.
