APE KZ Shim Under Buckets - Tappets

APE tappets locate the shim under the tappet to eliminate the possibility of the shim being spit out of the cylinder head. This is a must with cam lifts over .410 in a Kawasaki. The top surface to the shim button surface is actual Kawasaki size so you don't sacrifice shim sizes. APE tappets require use of APE titanium valve spring retainers.
