I have a 2019 Ninja 650, where I cracked the Stator Cover pretty bad. I've replaced the Stator Cover but the bike wont turn over, even after I replaced the battery. All the lights and electricity come on when I insert the key. I can only describe it as a "whirring" noise and it wont turn over. I done as much research as I could, but I'm not mechanically savvy. I was thinking it could be the actual Stator or rectifier, but I would like more qualified individuals for guidance before I take it to a shop. Id prefer to do it myself as a teaching experience and learn more about the mechanics. Any help is greatly appreciated! Thank you!
