I would think that the spacing between the poles would be the limiting factor for how many turns. :-k
And, you can't see that they went any farther beyond the edges in this picture:

GS850 stator thickness question

Hmmm... hard to tell if the core is skinnier side-to-side in order to fit more wire turns.
Or maybe -- just totally spitballin' here -- a smaller core, given the same number of turns, is more efficient or somehow makes better use of the magnetic fields in the rotor? I'm not an electromagentician.
Maybe they just got a deal on some skinny cores real cheap.
I'll be very interested in whatever Science experiments you can perform with this...

I got some shorter screws and mounted the stator to the cover. Tomorrow I will get the cylinders dropped over the pistons, install the head, cams, etc., etc. Not sure if it will be running by bedtime tomorrow or wait until Friday, but stator tests will follow soon after that. :encouragement:

Do you have a clamp on current meter? compare to results of a stock stator of similar model.
Measure ac current on one of the legs at several rpms. It will probably flat top by 3.5k.
1200,2500,3500,4500 is probably good enough unless you also add 2000 and 3000. Those rpms are equally spaced above idle.
i did this before using my TDS730 scope and power probe. A bit more tedious. Reading measurements off the clamp on at each rpm should go fast. Have a friend held and the biggest challenge is to get the rpm correct. Use an external digital tach. I have an inductive timing light that has one.

Steve, can I butt in and ask a question? (I'll ask anyway) What R/R are you using on your 850's?
Steve,
With the new stator being narrower, any thought given to how/if the new stator will be centered over the rotor magnets......?
Weither to use shorter screws... or.... put washers behind it to hold it further out.....?
Seems that the E/S person mentioned the shorter screws.
Seems like is functioning okay.
Proboably dont want to have it held away from the stator cover by washers, due to heat sink concerns.
But I still wonder about the alingment with the magnets.

I don't think alignment is an issue. Certainly not as much as the simple fact that it's smaller.
Now that the bike is running, I am noticing that the voltmeter sits right near 12 at idle. Yeah, it goes up to 14 when the engine speed goes up, but the stator that came out pumped out about 13 volts at the same idle speed.
Have not yet checked full capacity by loading it down to see if it does any better.

Sounds like the Power increase is 10% marketing and 90% bull.
They whipped the pixies harder.
Or... they got a shipload of GS500 stators in from Shanghai.
