Well the dl650 may or may not have the SCEM coating. Greywolf, don't change on my account, I don't know.
I do know my cylinder do have a iron liner, and after talking to a mechanic here that was formerly a powersports mechanic with a little knowledge of such things. I'll deglaze the clyinders as planned.
I'll continue to not know whether I have SCEM.
Kinda sounds dirty (SCEM)
cylinders are cleaned and put back together. I will replace the valve seals, but I put it back together so as not to mix up part locations. I'm not always very organized.
