Hi
I have been struggling with low compression (80 v. 120 on other side) in my left cylinder since I bought this 2001 V11 Sport a few weeks ago. I figured it was rings because compression jumped when I squirted a bit of oil in the cylinder. After trying marvel mystery oil and other things to free what I thought was a stuck ring, I finally pulled her apart. I am trying to figure out what I have. Btw - pulling other side off this weekend.
The piston skirts seem abnormally scuffed. Any thoughts would be appreciated.
Mike
