I wonder if the PMA rotor was balanced.
Any balancing signs on it?

Engine mounts & aftermarket components state of balance. I'm buying into those two suspicions definately !
Good catch, 2M! But do we really have to wonder?
Several years ago, I used some 3/8" ID PEX tubing cone-shaped black neoprene rubber seals to replace the old, expensive hour-glass shaped OEM footpeg rubbers. These are used on RV plumbing systems. Also used 3/8" ID reinforced rubber washers (2 per mount post), one on inside against frame, one under the thick chrome washer (sandwiching the peg bracket).
Much better than the wore out rubber. Unsure how that would compare to new OEM rubber...

Glad the cushions helped.... and I like your SV as well. I hope to add a bike like that to the stable one day.

On a side note, I'm going to do this tonight after the kids are sleeping.

Tomorrow I will check the engine bolts.Today I did s test ride with hacked footpegs (added the tubing around it as a test)
It DID reduce foot vibration, but is obviously not a good solution as it's breaking up after only 15 miles, but offers hope that the Harley Davidson thick footpeg rubbers will be a good fix.
The vibes are still present, but liveable, instead of painful between 3,500-4,000 RPM.
Will update when the pegs come in.
Took my '83 out for a twenty mile loop yesterday.
Con grosso respecto, I think you need to find out what's causing your vibes instead of masking them.

Yeah, no reason to wonder.............................its almost a certainty, that the PMA rotor he has will show no evidence of balancing.
