Tappet, Intake Gs450l 1985 (f) Usa (e03)

The Tappet has a tough job, and eventually the case hardened tip will wear through, and the valves will no longer open correctly for optimum performance.
If you are already replacing your camshaft and/or push-rods, then we do recommend new tappets as a matter of course.
Many other items to help you achieve a perfect cylinder head overhaul can be found on the CMS web site, valve stem seals, cam chain tensioners, and much more.
It is always worth checking carefully that the part number you specify is compatible with your model before placing you order, this helps avoid the frustration of ordering an incorrect part!

Helps ensure valves open and shut smoothly.

Worn tappets mean reduced performance and a noisy top end rattle.
