I tested the springs. The stock spring has 156# on the seat with 1.805 spring pack, protrusion 1.995", and 378# at .550 lift (~stock lift). These were taken from unaltered CVO 110 heads, used with low miles. I tested two sets and found all of them within 5% of my initial number. I realize this does not match Screaming Eagle specifications but are actual and the springs are used which is closer to real world.
Then I checked the AV&V 6000 spring, after working them in. Came in at 1.835" spring pack and was 174# seat and 338# at .550 lift.
My Rimac spring tester is recently calibrated with a Rimac and PAC calibration spring.
