im putting new rings in my wr400 thats never been opened before. the cylinder walls are clean with no scores. i can still see the old cross hatches.

my question is, do i need to hone the cylinder before i put in the new rings or are those walls to hard to even make a difference?

You still need to hone it. A glaze breaker will work just fine. Also use normall dino oil for brake in. Don't use synthetic! Good job mang!

Sure run a hone in there to clean that glaze off not to much so your new ring can seat faster:thumbsup:
