yz flywheel

[atvfreak400]

I got looking at the flywheel on my yz426 and I think that it is a wr flywheel the motor is timed to a yz. I have a yz flywheel would it make any difference if I switched them or would I be wasting my time.

the wr flywheel is heavier, so switching to the yz will allow it to rev faster...
