I have a 2002 Foreman 450 ES and I have rebuilt the top end twice now. The first time was done by Southern Honda Powersports and the second time, by me. After both rebuilds, it started smoking. Now I have found an engine off of a 2000 Foreman 450 F, I know that the engine will bolt right up to my wheeler but what I don’t know is whether or not I’ll have to change the wiring harness. Are the harnesses the same for both year models? Any info on this will be much appreciated, and thanks for reading!
