When we did put all 5 new valves in I did use lapping compound and cut new seats for the new valves...after lapping them u can see where the compound was hitting the seat and it has a perfect ring all the way around and was in thickness per the manual spec (cant think of it off the top of my head). It didnt get thinner at one part of the valve and then thicker at the other. It was an even ring all the way around.

This bike was a valve recall bike and the center valve broke in a very odd place. it broke about .5CM off the stem of the valve where the keepers ride and hold the valve up. (let me know if you understand that kinda hard to explain) maybe Anthony can chime in but there wasn't but 20hrs on the bike when that valve broke so i figured the seats were ok and it was just a bad valve.
