I found a weighted flywheel from an 03' yz 450 and was wondering if it would work on my 99' yz400f or would I need the mag with it too> Any body have any ideas on this?


I know a 99 wr400 fly wheel is different from the 03 yz450. Look up tool removal part #'s that should give you some sort of an idea.

Part numbers don't always tell the story. In this case, though, the answer is that the '03 flywheel will not fit a '99.

The flywheel will not fit a '99.

How about the weight its self will it work?
