Got a super bad vibration in the engine (I think). About 7/8ths of the RPM range. It comes and goes throughout riding it but it's always there. It's literally so bad my hands and feet go numb lmao. My dad thinks the stator threw a counterweight. Which makes sense but I just wanna explore all options. Thanks in advance guys
 
Thrust washers and crankshaft main bearings, or bottom end rod bearings are probably the culprit! Remove stator side cover and pull and push back and forth on crankshaft . Check to see how much crankshaft end play is in the the main bearings. Good luck! ✌️
