Timing Chain

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.

I don’t disagree. The real issue is that the quality of most chains produced today is not great and they stretch, thus causing other issues like timing jumping around due to the “whip” of the chain. I went down this rabbit hole 2 years ago. We tried 5 different timing lights, 2 different distributors that were ran on the test machine, changed out the MSD and coil, all came back with the same issue of the timing jumping around. Then did surgery, pulled the cover and found that the chain had a ton of slop on the driven side. Oh yeah, it’s was a Cloyes true roller chain with like 20 hours on it. Changed it to the pro gear I posted above. The timing issue was then corrected..
