Just tried my stock flywheel with the scrappy 11 pole stator and it fits beautifully. Based on memory and the pics I took, it looks to be the same size as the other stator I'm running now, so that's a good sign. That should save me a bit of cash if I swap another 11 pole one day on another engine.

Damn, I really want to find a donor bike now to try a few things to see if I can figure it out!

Id love to get my hands on a donor bike that came factory with an 11 pole setup to see exactly how the wiring was run.

I know this thread was dead, but i figured it would be a good place to post this because there was a bunch of nice info in it regarding 11 poles. Earlier we were talking about different wires and what not. But after having some wiring issues with my bike, I had my hands on three or four different 11 pole stators. I came to realize that there are (at least) three different size 11 poles.
These two are very similar in diameter and both fit inside an 8 pole flywheel. But one has larger coil windings than the other. It is kinda hard to tell in the pictures, but the stator on top has windings that are a little bigger than the bottom stator.

This stator is much larger in every way. The coil windings are much wider and taller. The quality of this one is far superior than the other two. This stator will not fit inside the 8 pole flywheel and requires a true 11 pole flywheel.
This stator below is also a little deeper and sticks out further, requiring longer mounting bolts than the other two posted stators (as well as 8 and 6 poles). I used 30mm long bolts purchased from advance auto parts (package shown).
This one can be purchased from Jay at Makoa Scooters.



I think i may have also realized that using an 11 pole stator that is meant to have the 5 wire rectifier (possibly the one with pink,yellow,white?)with a 7 wire rectifier will ruin the rectifier after some period of time.
I am also begining to think that the stators with the pink, white and yellow wires are meant for the 5 wire stators.

^ Good info there.

In other news, I'm beginning to think that the rectifier that El Captain and myself got isn't for an 11 pole setup. Check out what I've done with it and an 8-pole stator in this thread. viewtopic.php?f=171&t=71358&p=1238044

Well, the bike is running and the front of the harness is about 98% done. Looks like this rectifier IS for a 8-pole setup. Weirddddd.

Good info there ^^^ I wonder how much difference there is because of the coils. I wonder, enough to see on a multimeter, or just in overall reliability?

Did you happen to notice if the trigger pickup brackets on any of the stators had that little solder on it? Its a little wire coming out of the pickup housing, and then soldered immediately to the bracket.

It appears that the 5 wire recrifier may be used in some 8 AND 11 pole setups. And looks like the Makoa is gonna be the more stout stator, not surprising.

I was looking for that difference when you pointed it out earlier. Wasn't able to figure it out.

As fate would have it, I got my hands on about 20 of these last week due to an ordering mistake. It's an interesting setup for sure, I'm not sure yet for better or for worse. Notice the double ignition windings? They're the wrapped ones. Normal 11-pole stators have 1 dedicated ignition winding and 10 wired for the charging system, making them 10:1 - but this setup is 9:2.

I prefer to have every ounce of charging ability that I can (for high wattage lights, I ride mostly offroad), but this 9:2 setup seems promising for more advanced CDI ignition systems which may require a faster recharge rate of the internal cap. I doubt there would be much if any improvement on a standard CDI.

Should be interesting to see the differences on the scope. I'll know more about these and their output profile when I get a chance to finish upgrading the dyno.

Excellent! Glad someone will be able to REALLY look into these things.

I remember glancing at the different pick ups. My observation was that some had the wire soldered externally (you could actually see the solder on the back side of the pickup) The nicer pickups you couldnt see any solder and just saw some type of silicon glue (im assuming it was soldered internally and covered up).
