Andy, thank you.
My problem is to understand now. What kind of marking the 31100-KV3-771 flywheel has on his surface. I am not find any flywheel that bear the marking of the part number.
I see only this information on the flywheels. And how I see markings are different on the different flywheels. How to anderstand which letters and figures corresponding to 31100-KV3-771?
