The litterature on which the website is based on, are the books: 1. Design and simulation of Two-Stroke Engines by: Gordon P. Lasopaguild Two Stroke Engine Porting, Head Mods and Pipes. This section describes the basic function and the most important processes in the 2-stroke cycle a tuner need to consider in general and with the Bimotion tuning software in particular.

Computers and all the fine software have taken modifying and tuning two-strokes to a level higher that one could have imagined in 1973. A lesser work would.

We are racers ourselves and know what it takes to make a very powerful MODIFIED ZENOAH R/C Engine and to also be very reliable. We also professionally build boat hulls that are above the standard of other manufactures. Our detail and craftsmanship of our work goes far beyond most in the industry. We offer exactly what we race no matter who gets them.
