New Pushrod Tube Seals to replace your hard, tired, leaking old ones. This is a much easier job to do than at looks at first and can be done without taking the cylinder completely off the bike. Of course, the best way IS to take the cylinder right off, clean and inspect everything, maybe even replace the base gasket and head gasket while you are at it. Hey, you’ve gone that far, why not install a Siebenrock Power kit along with those pushrod tube seals?!
Sold as quantity one (1) for BMW Boxer Airheads after 1975. Four needed per bike.
