I'm not well versed on the cam drive specifics but the inner always wears faster than the outer. Not to this degree, but still...
A few thoughts unrelated to engine-specific junk.
-Spring manufacturing tolerance (more than nominal on inner, less than nominal on outer)
-Shoe material tolerance.
-Burrs on inner chain.
-Tensioners were not replaced in sets.

"Tensioners were not replaced in sets"
Specifically I wondering about this. How many miles have you put on it yourself

Only around 3000... And I would be surprised if the outer had been changed in the past, considering the mileage. Although, looking through the pile of receipts I have, the original build used SE211 cams which were changed out for Andrews TW60s a year later... I suppose one tensioner could have been changed then...

Any way to test the chains for integrity?

Hey, a question for those in the know that are watching...
The recent engine builds all show guys buying specialized holders for their runout measurements. Any reason crank runout can't be measured with conventional dial indicator holders?

But in hindsight, I think this particular step would have been pretty simple with a universal holder of some sort.

Thanks guys. I figured as much but being uneducated I hated to assume.
I have a chest full of measuring equipment for engine building but this is my first V-Twin. I'll be opening her up in a couple weeks...either to replace just tensioner shoes or the entire contents of the cam chest...depending on what I find.
