S&S action question

[Phil Bondi]

I have been asked to get this action to feel lighter. Right now it feels 
like a Mack Truck. I have not measured DW yet, but it feels like mid 
60's to me.

-there is only 15mil from knuckle to bushing. I measured it 3 different 
times getting the same result.

-Hammers, shanks, knuckles, and whippens have all been replaced, but I 
think I'm fighting an uphill battle without replacing those shanks.

Your thoughts?
