Here is what I found.
Due to a crude scale I can't be as accurate as Motorrad but you'll get the idea..
Stock used Kawasaki 86mm piston with minimal wear no window.
Piston .9lb with no rings
Wrist pin .2lb, 18.89mm OD, 11.25mm ID in the middle but it is tapered internally on both ends, 63.82mm long.
Wossner Stock new 86mm with window
Piston .8lb with no rings
Wrist pin .15lb, 18.89mm OD, 12.8mm ID, 61.03mm long.
Wossner modded by Motorrad used 90mm and slightly worn with window
Piston .9lb with rings
Wrist pin .15lb, 18.89mm OD, 12.8mm ID, 61.03mm long.
Wiseco 86.5mm with minimal wear no window
Piston .95lb with rings
Wrist pin .2lb, 18.9mm OD, 11.85mm ID, 63.37mm long.

Oh.. BTW people.. the wossener wrist pin is LIGHT! only 72ish Grams (or was it 74...) either way.. its about 10 grams lighter than stock..
Wrist pins comment by Motorrad:
But the OEM wrist pin is about 4-5 grams lighter than the Wiseco one...
10 grams = 0.0220462 lb

Didnt you have a titanium pin?
Motorrad:
Just picked up new mains. $13 each for old stock german FAG rated to 24,000 rpm
Motorrad:
Yep. but not in the bike. YET... still need to run a gall test on it
alward25:
U want another to test?
If bikes are for kids I'll never grow up.
