Does it matter that the new one is thinner than the old one? I'm used to replacement parts being more similar. It seems to fit pretty well in the old one's spot. I can snap a pic of that if needed.

If you search for stators, there is a lot of in-depth detailed information on them. I just don't remember the link. But Stators are the top sticky on technical discussions.

I've read the bulk of the "burnt stators" sticky thread - that's where I got the link from invader to buy the new stator. I didn't see anything in there about mismatched sizes.

thanks.

The core thickness is the same as OEM? I've never seen this before. The Wizard can tell you how much of an impact it can have on available power output. I do like the smooth outer surfaces. How do they compare in weight?

So looking back on onewizards comments he stated "
the OEM has a larger amount of turns or magnet wire closest to the top of the pole, this is were the magnetic field is strongest, so the rewind may have a slightly lower output.

I will also comment that it appears they use a epoxy resin on the rewind, IMO that is the best and one of the most important part of any stator, in fact if I was given a new OEM stator, I would take it into a motor shop and get them to put a second dip and bake on it, might cost you $10.
Bottom line is if it does the job, who cares"

So maybe voltage might/will vary. I think what would come into play is the diameter of the stator new to old. If the same then the new with finished poles would provide a better surface for magnetic field. Then maybe the coil would not have to be as large to get the same or near output.

But thats me guessing. Definitely PM onewizard. Or go on faith you bought a part that was made to be a suitable substitute.

Stators

I installed an RM Stator about 1 month ago. I was also concerned about the thickness? Installed a series R/R and a Chinese digital Amp meter along the same time. Turns out I have 25.9 amps available?

Core thickness does appear to be the same as the old. I got it installed in the cover last night - I didn't have a lot of time to look at it but it looks like the rubber grommet will have to be shaved down to allow the gasket to sit flush.

Other than that, it seems to fit well enough. I'll give it a shot.

That's why I asked if the core was as thick... For the visibly thinner RM stator, spacers are required to have the stator aligned with the generator's armature.

Is the ammeter installed in-line? Wouldnt this indicate the bike using 25.9 amps?

You technically have a ton of amps available (until you pop a fuse)

So if I understand it correctly, If my stator goes out and I get a delta wound replacement the factory "shunt" regulator is fine. But if the replacement is star or Y wound a series regulator would be better?
