Bad stators are common with the Gen II FZ1's. I'd replace the bearings while you're at it. My bearings went out at about 50,000 miles.

Yep doing the bearings too, at the 50,000 mile mark just now lol. This is a fairly common problem with the old design it seems. Lasted ten years and 50k though. Should probably do my wheel bearings sometime soon too, rear has a slight wobble when in the stand



There are some cheaper parts out there but I only wanted to use factory ones... So I'm paying for it lol.

How would that or the fuel pump effect the stator?

The stationary part of the generator system. https://en.m.wikipedia.org/wiki/Stator

The thing that looks like it belongs in Iron Man. Lol. I didn't misspell starter.

You guys hush about that shit Scarlett might hear you. I don't have 50k on her yet, but I don't want that issue.

Yeah it's not a cheap one either. The rotor killed the stator, bearings need to be replaced as they seem to put the rotor off course. And you have to drop the oil pan to make sure all the crap is out.

Mine isn't all that bad from what I've seen. Others had the bearings seize up and all the parts fuse together, there is gearing on the rotor that doesn't come with a new one. All my stuff came out super easy thankfully. Also looks like I didn't loose too much of the magnets and plastic housing, others were covered inside the engine.


I would suggest testing the voltage on yours if it ever seems to take a tiny bit more to start. At one point I remember thinking I needed new spark plugs because it was slightly slower to turn over, may have been not having as much juice.

When it went, for me, it sounded a bit like a super charger whirring. I thought it was a new sprocket I just put in. I probably did 50 freeway miles on it. It whirred louder as it went on.

Nope, turns out it was the flux capacitor. It ran out of gigawatts and needed to be refilled. Plus my blinker fluid was low and that didn't help anything.

If this is a know problem are there any factory or aftermarket rotor upgrades? If not and the magnets seem to come unglued around 50K you should probably change out the rotor every 35-40K.

The new rotor has a cylinder liner between the magnets, 2014 is when they made the change. There is picture of one a few pages back, next to an old one with no more magnets. From what I've read you can use the new rotor with an old stator. Still like $360 for one but if it goes out it takes the stator out and that's $250 on top.
