Hello I own 2 scrambler 500’s an 01 & 04 ho ,the 01 has eletrical issues but everything else is in great shape. The 04 has been wrecked and she’s smoking now. I was going to try and rob all the eletrical of the 04 and place it on the 01, but the flywheel and stator are a quater inch smaller ID . Theyboth mount the same and the OD is the same. My biggest question is – Are the flywheels balanced to a particular engine or are they interchangeable ? Any help would be greatly appreciated.
