Can you add reverse to an 02 RMK by changing the CDI box, CDI box wire harness, left handlebar controls and cylinder head to an 03,04 or 05 issue parts? I imagine that the speedometer that has the reverse light, could also be changed out. I noticed that the stator is exactly the same between an 02, 03, and 04. The only difference in engines between 02 and the 03 and 04, is the DET sensor in the cylinder head.
