After being in the shop for a week, the shop finally called and told me to come get my bike. When I got there I asked what the prognosis was. I was told that "at this time the problem is not to the point where tearing the bike apart is warranted, if in the future, the problem worsens, it will be dealt with then". I was assured that the fact the bike was brought in for a noisy valve train is documented with Yamaha. And that is it for now I guess.
Bananas!
