    I ordered 2 gaskets 1 came in its proper packaging while the other was loose ( no packaging ) and is torn.

    Yakima had the parts diagrams for free, very good prices, fast shipping, and excellent customer service. I highly recommend them! Thank you!

    Removing the rocker Covers made the Spark plugs accessible. The new cover gaskets were required for reassembly. Adjusted the Valve lash while I had it open! The right part, on time.
