When I moved the flywheel the crank was smooth. The bearings were a little loud though but still smooth if that makes sense

Kit was prepped
The sound is so borderline "bad" and I've heard that E50s are just noisy as hell so I'd thought I'd ask.
My local moped guru is all about "Fuck it, ride, bikes are noisy" but I'm so paranoid about breaking shit with my ZA taking a shit a bunch of times that I can't ignore it.
