That stator will work fine. It’s a shame you didn’t know this before, you could have bought a 3 phase high output stator and regrec and never had another battery issue again. The nice thing with the 3 phase kit is you reach max output at 2000-3000 revs, with single phase I believe max output is something like 5000+ so unless your giving it some you don’t always meet max charging capacity. However you should still be fine with the RM23 which you’ve linked there. It’s still better than stock.

Now let’s all have a beer beerchug
