Sounds like the same noise I get from my 145, but  I think mine comes over 
the audio.  There another, quieter click as I switch to slow speed but that 
noise is strictly mechanical in the motors and is much more tolerable.

IMHO, I'd go for the motor upgrade.  I've disconnected my lower motors to 
see if the "Memphis" sound  is for me and connected them right back up 
again.  On the other hand, I'm not especially keen on the lag in winding up 
the lower drum compared to the horn.  In fact, I was considering posting 
something asking what people expect on average for slow-fast wind up time on 
the drum - any takers on this?  I've played ad infinitum with the drive belt 
tension and there is definitely a "sweet" spot, but it still takes a few 
seconds to crank up.

 Actually, It would be interesting to hear a Leslie in which both the horn 
and lower work on slow speed, but only the horn spins at high speed 
(opposite - sort of - from you situation).
