Plug

Valve drive-train components suffer wear and tear over the years and miles - during a refurbishment of the assembly renewing this component should be the default choice. Ensuring the cam-chain is tensioned and guided correctly is vital for top performance and reduced mechanical "chatter". Renewal of the cam-shafts themselves maybe required, check the lobes carefully for uneven wear patterns.
