Yeah, I can second skrapion's comments.
I have very little experience with bikes (I'm on this board because I'm considering buying a '04 Savage), but I have a lot of experience with aircraft and VW engines both and valve noise is expected there. In most cases, no valve ticking is a sign of too-tight clearances (or way way WAY too loose, but it's usually hard to start the engine that way!
)
If they're just a little too loose, it sounds like a samba beat to me, personally. The point is that there's a syncopation - the valve lifters are not quite hitting every rev (also, she'll probably idle like cr*p...)
Anyway, it's been my experience as an aircraft mechanic that while the safest flight might be the one that never leaves the ground, it's certainly not the most fun. As someone once told me on a VW list - "there ain't no mechanical problem that can't be solved with a quarter in a pay phone, so grab a quarter and head for the border."
Good advice to us all. Of course, now I have a cell phone, but still good advice.
