First time doing a ring job and valve lap and I am getting the parts together.
Rings arrived last night (Yamaha genuine parts). The package has several rings in it. I understand that some are different, and I can tell by looking at the piston where they seem to go.
Questions:
Some of the rings have an "N" stamped on one side. I presume that means something like "North" for this side up on installation. Is that right?
The thinner rings have no stamping, so I presume they are not oriented on install. Is that right?
Also, there are more little rings than are presently on my pistons. Should I install all that were in package, or faithfully replicate current installation, or something else?
And of course, I will check the end gap on all rings prior to bolting things down. And I have a ring plier to ease fitment. And I will use lots of oil.
Any other thoughts?
Thanks.
