I have an 03 Predator 90 that lost spark. I know this is often caused by the stator.
I am going to do a proper diag today, but I happen to have a good stator off an 01 Scrambler 50.

Anyone know if they are interchangeable?

 

Weird situation,but appears they can interchange. The 2001 Scrambler 50 OEM original part # was 0450522.
The 2003 Predator 90 was # 0451000. BOTH have updated to Oem# 0450998. By this I would ASSUME that that the 50 stator would work on the 90..In case it doesn't work you can take a chance on a Chinese stator from ebay that's supposed to fit Polaris, Eton 50/90 machines.

Got lucky. Took it apart, the stator was very dirty. Blew it out really well, and it fired right up.

Thanks for the help again.

 

Yep got lucky on that one. Most times I had to replace them was because of kids treating them like submarines and shorting out the stators.Hard to keep water,dirt and dust out of the stator area with the way the air intake and cover are designed. Later 4 stroke models changed this a lot.
