Okay, I just went back out in the garage to investigate some more.  I
peered in and watched the balance shaft gear rotate as I turned the
engine (there's a clearing where you can see maybe 3 or 4 teeth at a
time.  I found one tooth with a line marked in it.  Ahha!

Then, I watched the crankshaft gear.  There are 2 teeth together that
have little circles imprinted on them.  Hrm, maybe this is what the RPM
guy was talking about lining up?  

Still, you can't see where the two meet because it's obstructed by the
case.  So, I made a reference mark on the timing gear on the end of the
camshaft and a corresponding one on the end of the balance shaft.  They
seem to rotate 1:1, but they never line up!  

I'll upload yet another picture here shortly.

Maybe I'm doing something incorrectly, but I wouldn't doubt they were
this much out of phase, based on the feel of my bike.

Laters,
Brian
