These are some good motors, myself and my team mate just got them for our NTC3's and man do they haul, wicked low down snap (in fact tooooo much) and very good mid-range and top end.

It is also easier to start than my old motor by a long shot and idles very well.

Overall I am very impressed with the motor, tore it down before running it and the internals look good, and fit and finish is very good plus it's blue
