1983 250CR ignition- PVL question.

Does anyone know how the weight of a stock/OEM internal rotor on a 1983 250CR, compares to the weight of a PVL rotor?
I know the PVL rotor is lighter, but I am wondering by how much?. I plan on adding a PVL rotor weight to mine but I am having a hard time deciding what size weight to buy. I no longer have the OEM rotor to figure this out on my own.
Thanks

I doubt there is much difference between the stock and PVL rotor. If you had a Mini 6 with the external yes, but the difference between the two internal rotors would be negligible in use. Also, I have used the add on weights for the PVL and because of the small diameter the effect of the weights is not as noticeable as you would expect. If you think you want an add on weight just get the heaviest one.

Thanks Kartwheel. Thats what I just did. Ordered the 20 oz.
