[Shotimes] UDPs?

[Donald Mallinson]

Jason, yes the SHO engine is like most, balanced at the crank/rod/piston 
area.  The front crank pully is just a dampener, dampening out harmonic 
vibrations.  Not sure if harmonic balancer is correct though, that does 
imply some sort of balance to offset balance in the rest of the rotating 
mass, and that isn't true.  it just takes out high frequency vibrations, 
like they have no most engines for about 100 years.
