4 Rotor Build in Sweden
I bought a bunch of new rotors. How do I comfirm that they are 9.7:1-compression?
I have weight them, but all the newer rotors have the same weight. The 28cc in the comb-chamber are kind of tricky to check, or?

The build continues.
Bought standard lock rings, but couldn't let them be standard.
Grinded them from 2.5 and 3mm with friendly tolerance to 2.00mm

The it was time for the grooves. Did them +0.03 to +0.05mm in height to get the right feeling. They are easy to install, and sits solid when released.
