Thanks! That finally did the trick. I think the first set I received was probably mislabeled. I'm guessing they were actually 2.5mm sizing not the 2.381mm/ 3/32 size as labeled. Replaced the saddle balls and the saddle piezo pickup is back up and working. Really appreciate the help!

I have this same issue with a 96-97 Nitefly with 4 saddles missing the balls but have been unable to source replacement ball bearings. I have established that the other 2 saddles work so I'm assuming the other 4 do too. One guy on the Parker Facebook page said 3/32 size bearings which I ordered from...

I'm trying to track down all pertinent info on this PM-series Parker I picked up. Can anyone help me?
