Cam Chain Life span?

[Rickrod3]

Currently tring to unstick an engine. I know I'm going to have to pull the head to decarbonize the top end. If I free it I can save the cam chain. Unless it was replaced which I doubt has 43K on it.
How long do they last?
TIA

If you are not going after ring problems, There are several ways to deal with carbon issues w/o pulling the head. Last choice for me anyway. Cam chain is good for 100kplus

My 1980 std has done 373k miles since new,
I am its 2nd owner. ( 1 yr now)
in that time it has only ever been service and had 2 clutch pacs.
The PO was fastidious in his maintenance
Except for a after market exhaust, every thing is stock.
So 373k miles for the cam chain. I think you could call that relyable eh.
Mind you the PO never thrashed the bike either.

When you have yout CCT out, look at the bolt marks on the plunger shaft. This will give you an idea of how much adjustment is left. Once you run out of adjustment, the chain needs replacing. The Venture CCT mod will give you some extra life on the chain because the plunger extends further than the stock unit. Remember, the more slack (wear) in the chain, the further the cams get out of time. A new chain will "pep" up the motor.
