New revelations on why my Stator fried

So I pulled my stator and I noticed that it was trashed by my rotor which has apparently a slight wobble to it so my question is is it normal for the rotor to have a slight wobble? All of my problems began when I hit a bump with the bike as I was pulling into my apartment complex I was riding two up I'm imagining that the added weight added extra force to the bump as I pulled in.. I guess I don't want to pull my engine bad enough that I would s contemplate getting a smaller stator instead if it would fit, or even if it would fit would it work and produce enough charge?

a wobbling rotor could be a sign of the rotor being installed wrong or crank bearings going out or a misaligned mod plate

a smaller stator will not work and seeing that that stator in the picture has green on it i am going to assume it is a caltric or electrosport both of which are very cheaply made a good one would have never split the way that one did

going to echo every thing new rider said.. and add possibly a cracked rotor (it can happen in theory).. or a Bent rotor.. either of them will require a new/known good used replacement.

since I have never had my rotor off, I don't know the answer to this.. is the crank tapered at all, even to the order of a couple thousandths of an inch? if so, the taper on the crank or the taper on the rotor may be worn, in which case, you need to replace the bad part.

on the tapered question, also, if tapered, it could be possible for the bolt holding it to be slightly loose (not properly torqued) and allow a wobble.

AGAIN, I don't know if the crank is tapered, this I just a possible cause if it is.

another thought. was a 3 jaw puller used to remove the rotor? if so, they can bend them (and I believe, the rotor is pulled using a single bolt in the center, right?)

I seem to remember someone a few years back that had the same problem and it turned out that the rotor had been installed incorrectly and had a worn key or key way. Either way it wasn't on straight. Someone else it may remember it better.

So my worst nightmare has come true I have to pull the engine again. This truly is depressing thank God it's winter and I have a few months to do this. I had to pull the engine the last time using a series of ratchet jack straps hooked to the garage beans above cuz I don't own a motorcycle engine jack what a pain in the gluteus maximus !

Denny, I remember it all too well as I have done it.

Grousehunter, did you remove the rotor? I didn't have it torqued right. When you get it apart I would check that first. Sorry you ended up having the nightmare.
