      no need for an app, the GP runs a proper carb and doesnt require constant jetting attention a la rotax.  Ocala Gran Prix is a great source of information for the Rok motors, they’ve tested the GP and the Shifter since the first one’s showed up in the States.  Might want to give them a call.

      Would be nice if there was an App, like we had for the Rotax. There is not even a chart in the Manual. Been running a 125 main, experimenting with a 128 as it get cooler. I was told these carbs are more or less set and forget. If you learn any more, please post. Would be nice to see usage of this engine in TAG Grow. It is pretty well engineered and so far reliable. It’ got a little more top end than the ROTAX, a dog on slow starts and respectibale in the middle.
