Why does the VPI motor thump

Why is it when I turn off my VPI motor I hear a thump through the loudspeakers? The only direct connection to the stereo is the belt.

I change LP side, clean LP and stylus, start the motor, wait for the stylus to drop into the groove then I un-mute. No thump through the speakers with the preamp muted. Mofi's explanation about the capacitor issue is a long running problem with VPI motors.

Luck? Or do you use the mute switch too? No one said that every single motor VPI ever made thumps, but obviously there are enough of them out there on the market that do thump that threads like this are very common. Search the archives here and at AA, you'll see that this is a common problem.
