Uh, what the hell were they welding down in there?
Harmonics are a ***** and if that counterweight were to lose integrity at high-RPM, it's liable to compromise the integrity of your oil pan and rear tires.
There's other, far better, ways to take weight off a crankshaft, and the piss-poor machining on that one makes me think Yang-Li doesn't really give a crap.
I wouldn't run that thing in my lawnmower.
