So just replaced my stator on my 2007 450 Sportsman. I used an aftermarket Rick’s Motorsports stator, #21-560.

The bike will now begrudgingly start after a bit of cranking (always has been a quick start), and will only idle with throttle applied. It will not rev much beyond idle.

The obvious question is why… any suggestions?

A few things during install:

Had to use the original plugs, as the replacement stator didn’t have any. The 3 yellow leads from the stator didn’t have any numbering that I could see, so I connected them in no particular order. Is there a correct order?

The lead that heads to the front of the bike with a brown wire, a white, and a white with red stripe (the 2 whites come from the pulse coil). The replacement had different colors for the 2 whites. I took a guess on putting these into the plug, since I didn’t know which new wire corresponded to the OEM stator wires. Could this make a difference?

Thanks for any help/advice you can give… and please ask if you need more information!
