Anyone ever know of these chains stretching and jumping a tooth? Or was my timing put together wrong at some point and the chain was fine? I brought this up at the shop and the tech asked the mechanic whether the guides were broken. They were not.

Please any commments appreciated. Feel like I got hosed for the price of a new kit ($270).

Thanks,
Bryan

>>>*While it is possible for the side plates to get hot enough for the metal to actually "stretch" my feelings are this is not what actually happens.

There are several wear points, the outer roller spins on an inner pin so the pin can wear, the inside of the roller can wear, the outside of the roller can wear and the side links can become loose and add to the total.

Considering there are 96 links on the late design and 98 links on the early, we can see quickly that this can stack up to a LOT of added length.

I have seen chains that are pretty long, those I can tie into knots. A new tight chain can't be, they won't flex that far.

So if a chain is running way too snug for some reason, like we will see if a 20R or 22R head is on a late 85 & up block without enough metal milled off, then it can and will wear quickly.

We know the chain will elongate, that is why the system incorporates a tensioner in the first place. If it didn't, there would be no reason for one.

Of course the tensioner has limits, and if the assembly gets worn enough, it can jump teeth rather than completely breaking...*EB
