I guess you are talking about the magneto. No that does not have to be changed but you will have some wire swaps to do since the 99 and 00 use the old harness.did the stator also need to be changed -out? for an 03-07 I just got a 03-07 hub for my 1999.
How is it running compaired to the 16bit?
Back from the dead. To see what bolt it was to remove the hub.snapped crank case bolt...ouch. Invest in a torque wrench?
