I found it's best to buy factory yamaha coils NOS off ebay. Rewinds lasted me 6-7 races and crapped out. Rewinds or chinese ones use heavier gauge wire. They don't Ohm the same either.
Yamaha used a ultra fine wire then encased them in plastic. Stator companies don't like to use the fine wire as it's difficult.
My rewinder said best to go factory yamaha as a result.

Late to the party, but for my YZ125H, I used a coil off a YZ80 stator when mine went south.
