Cam Chain Stretch

You will never get an accurate measurement on a cam chain. The sure way to check is to install the chain and cam. If the cam drive gear marks line up with the head then the chain is fine. If not and it looks like the mark is about half a tooth off (it's always the forward mark being up) then that right there tells you the chain is stretched. Even if the chain is stretched the bike will still run. The cam timing will just be off a few degrees. More low end.
