If you got away with .060 I think I will try it as I have cast iron.

Yup, they're quiet as a church mouse, especially with my new custom fixed length Smith Bro's pushrods.

Where do I take that measurement? Exscuse my ignorance on this, never had a hydraulic drivetrain harley, especially with adjustable push rods

Don't take this the wrong way but are you familiar with setting pushrod length with adjustable pushrods?

Ya know, turning the lower portion of the pushrod a certain number of "flats" to get your lifter preload while the piston is at TDC on the compression stroke.
