Oooh. Thanks for the info, Coyote. I went searching for said photo @ TS last night with no luck. Comparing your pic to mine of the XFi piston, the oil ring looks set a bit higher up on the XFi, but it's nearly impossible to tell from 2 different pics.

Anyway, I wouldn't tear the motor down just to pull off a compression ring, but I'm considering shaving the head as well, plus swapping in an old (potentially softer) set of valve springs. Time to start making use of that old 1.0L I pulled from the blue ForkenSwift.
