EK cam chain for the Honda models listed below. This is an endless type chain and it does not come with a master link. If you're rebuilding the top end and replacing any of the cam chain tensioner / slider/ guide parts, it's a good idea to replace the chain as well. It's cheap insurance so you know it's new, follow the "while you're in there" ethos.
