Thats always a concern for many of us, so many of the older type cranks were so badly balance and untrue they would vibrate you to piecs when they revved up a little.
It ran just fine. Probably the same as a regular GT5 kit. Shook like any stock motor would. Which we remedied by lightening the piston. Then it ran great with little vibes.
