So after doing the ebr rotor upgrade I didn't get the nut on tight enough and it started to make some bad sounds. Took it apart and the retaining ring on the back of the rotor had come free. Put it all back together and now it makes the worst grinding sounds on start up. Fml. Is the sprag clutch fubar'd or should I fire my mechanic? It's possible I still don't have the nut tightened to 300ft lbs as I don't have a torque wrench that goes that high. Help
