it was a joke Verslagen ...

Have ya'll been drinking the stuff out-a-of a mason jar ?

Mineral or Petroleum Oils
A non petroleum oil product ....

Uh huhh,, I get it..

I'll stick with a Pina Colada!

So, theory has it, the pawl catches a tooth after a ride. Next warm up damages the chain.
I think a wimpy spring would be less likely to catch the tooth so early.

Any kind of compressible material built Into the tensioner arm, to allow the chain some room even after the pawl snags a tooth.
This is a stiff segment.
And, if a disconnect could be built in, disengaging the pawl at the end of the ride. Be cool to be able to pull the tensioner off of the chain a tad.

In short, I think a Wimpy spring inside the tensioner and some compressible material to make it Not a solid rod once a tooth engages. That could happen in the mount or where the tensioner starts transitioning to where it attaches to the guide.
I think the mount makes sense for two reasons, easier and it could be done so as to move the tube of the tensioner closer to the chain, allowing the tensioner to Not be so extended with a new chain on.
The maximum movement in this area could be designed to no more than 1/8" to accomplish what I am envisioning.

The first thing I would want to see in testing would be what our young intrepid batman has done.
Second, replace the tensioner spring with a soft enough spring to not be able to get into a new slot so quickly.
See what that does.
If it's good enough, call it done.
If not, then look at a way to mod the mount end of the tensioner and put a spring in that is stiff, but limit the travel.
From there, it gets tricky, electrical stuff, relay/ solenoid to disengage the pawl while the bike cools.

And how much OOOMPH would That take? And how would it stay there, while it cooled? And how does it all get put right before you start i t again?

Yeah, tricky.

Maybe a remote operated electrical/manual adjustment. Push a button, engaging a solenoid, spinning the adjuster. Like the drum brakes..

on the girly cocktail side -

tastes just like Double Bubble bubble gum

The spring sees very little load.....the pawl is what bears the force that the chain guide imposes once the engine has expanded and grown in size.  Aluminum has a coefficient of expansion of around 13 micro inch/inch/degreeF...while it is around 7 for steel.  So the aluminum case, cylinder and head grows 85% more than the steel chain as things get warm, and to make it even worse - I suspect the cylinder and head get hotter than the cam chain.
