Since I have the motor apart it wouldn't hurt to be sure. I had some oil coming out of my exhaust and leaking from the pipe when I took it off the bike, not a lot but enough. It's probably due to the rings not being seated and/or my cam tensioner being installed incorrectly.
I have the two scraper rings (connected to each other) installed first into the bottom groove. I have the redish brown ring with the writing "n100" facing up installed next. I have the last chrome ring installed on top and it didn't look like it made a difference which side was up.
Thanks.
