Does anybody have any knowledge of the control unit for a 2001 TRX450ES, part # 38910-HN0-A12? Is it supposed to be completely interchangeable with part # 38910-HN0-A11? The part I removed from my ATV is part # 38910-HN0-A12. Looking at Honda parts manuals, it appears that Honda has replaced 38910-HN0-A11 with 38910-HN0-A12. I ordered a new control unit 38910-HN0-A12 from Babbitts part store, but it does not match up with the one I removed from my ATV. The part #s match, but the part itself does not. Two parts side by side attached. Dirtier part is one removed from my atv, other one is new part. You can see the holes are smaller on the new part, and one of the corners of the new part is not completely "rounded". I also bought a used one off of ebay, and was sent the part # 38910-HN0-A11, and it matches the one I received from Babbitts exactly.
So my question is, has Honda changed this part all together? I cannot seem to find one that matches the part that I removed from my ATV, even though the part #s match.
Any help is greatly appreciated
if ya haven't figured it out by now ?, there is no telling who, when, where, how ?, someone may have swapped parts out from one make to another in the atv world !. they just toss parts at them, hoping to get them to run/ride !. I have seen some pretty weird stuff in my 25 plus years of rebuilding atvs, atcs, almost nothing shocks me anymore !..lol.
