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!
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.
