I am not being critical, what you are attempting is incredible !!!

All I ask is if you dyno a M103-12V that you are building for above 7000 RPM limit that you post a dyno chart.

I'm curious of the power peak, shape, and area under the curve.

Not many two valve per cylinder engines can breath and operate at the high RPM's that you are looking at !!!

Thanks your effort in the experimenting with the limits of the M103
