  Hey guys, I had my stator changed a few days ago. Today, my sprocket nut just came out spilling all the brand new oil. What do you guys reckon? I killed the engine as soon as I was accelerating but wasn’t moving.
  
  Can it be a loose bolt or something more serious? Cheers

  It means you will need a new nut and a new washer (look at our shop bove ^)
  
  And look at customer pictures, the nut needs to be 60 ft lbs torque tight ==> then fold the lock washer 2x to stop the nut getting loose ,
  
  The nut fell out because nothing was holding it anymore (the washer failed its job or it was not tight or folded properly)
  
  Also put fresh oil again (see tutorial below) and check the engine runs again before riding it. Check for leaks again.
  
  If it is leaking again, when it is idling, = take a picture and show us.

  The only issue I’m concerned about is how did all the oil spilled from the sprocket? Is that pretty normal to happen for a missing sprocket nut?

  No a sprocket nut coming off won’t lose oil, there something more, it could have damaged the oil seal or worse broken a cover, only way is to take a look.
