Just got a loaner E50 motor today while I rebuild my zah. Crank looks great no play (maybe a mm of side to side)
Threw a stock 50cc treats kit on it. Refilled the trans fluid. Set timing.
Shit runs cool.
It's noisy as a mofo though. A little engine shake at idle. Once you get it going it's cash though. Is this the cranks death rattle?
Definitely not hitting the head.
