Timing Chain

Most newer designed engines that use a timing chain also have a tensioner designed in to keep tension on the chain. Even motors from the 60’s like the Jag 4.2 straight 6 had a tensioner from the factory. My Kawi ZX6-R that revs to 17,000 has a timing chain tensioner from the factory…. It’s used for a reason… so to each their own..

Just because tensioners work/are needed in other applications doesn’t prove you need a factory designed tensioner on an LA engine.

The need for, and the functionality of, a tensioner are completely dependent on the design of the engine and the tensioner. Lots of newer engines have multicam systems too, and longer timing chains/belts, which makes a tensioner(s) much more necessary.

Just because your Kawi has a tensioner and it revs to 17k doesn’t mean you need a tensioner on an LA, or the that an LA tensioner is capable of revs anywhere near that.
