KX500 piston comparison

[Sandblaster]

I am going to compare pistons and wrist pins to see who sells the lightest of both.
Remember, the heavier the piston, the more energy is used to get the piston to accelerate and decelerate.
Also, the heavier a piston is the more energy is spent changing the direction of the piston from going up, to going down, ect...
I don't have a lot of pistons to compare but here is just a few.
I will add more as time goes on.
Also, my scale only weighs in .05lb increments which really isn't the best for this sort of comparison but it should give us a good 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.

don't forget about the light pin David got from me.

I need to get a different scale because what I'm doing is really not accurate enough.
