Will you outline the process of getting an aftermarket piston approved. Was the aftermarket piston identical to the OEM piston as to weight, ring grove size and placement, compression height, and top of the piston?
Thanks

You get extra kool points for having a third petal and fresh air to the engine. Your team has a wealth of knowledge. It looks great hope to see you out with it this year.
