I thiink trials have shown that removing the pawl has no ill effects and Seriously extends the life of the chain.
When the engine gets taller from heat, it pulls on the chain. IF that Pawl has just grabbed a new tooth, it will NOT give, and when the engine heats up, it gets taller, and strains the chain more..
There are several ways around that, but the most direct is, ditch the pawl,,
I think it is Batman who did it first.

Guilty as charged, having never rode my bike gently , but I believe that the quality of cam chain has changed over time. My 95 didn't need an extension of the tensioner until 19,000 miles but since then has shown little to no further stretch by removing the paw and it's spring . Current mileage on the original chain is 39,000 miles (-starting it's sixth season - that 's if it wasn't 32F and snowing today

Batman...
You ditched the spring, too?
I wonder what the chain is doing as rpm change,,
I can track with ditching the Pawl,,
But I'm confused about being gutsy enough to toss the spring.
I know you have plenty of miles on it to prove it. I know it works..
I just don't understand how..
And Since it works
Why do manufacturers build these things with such self destructive tensioners?
Cam chain issues are common on lots of bikes, and apparently, needlessly.

JOG , I went to a shorter and heavier spring , with the stock spring and the piston being pushed back into the body ,I was afraid because of the continued movement that it might bind or fail. Use of a shorter , stiffer spring with more open coils allowed more movement and slightly more pressure . There are two times when timing is retarded ,at cold startup and when the TDI reaches it's max advance (5000 rpm) ,the constant pressure I apply to the guide aids during both. Outside of a tuned air intake and a stock H-D muffler my bike is completely stock from the carb(highly tuned) to the exhaust header yet a WOT run a week ago produced a top speed of 94mph. I run 70 on highways with a healthy reserve for passing.

YOur answer to the tensioner issues is a really good one..
You could toss me all the right goodies to choose from amongst options and I would never get a carb Top Notch,, Im an 80% er,, at best.

Those are hunks of plastic foam used for shipping fragile stuff like electronics items. I just ripped the foam to fit after testing it to see if engine oil would dissolve it. I tore the pieces a little big so they had to be squished into the mouse holes. The tension kept them from falling inside.
