This is from this past Sunday where I tested the first mod I did to the engine. It was some simple work to the sleeve and the engine gained a noticeable increase in responsiveness while maintaining a smooth, controllable power delivery. The power band also became very linear and predictable so it made driving the buggy, which is usually a hassle on this track, much easier and far more enjoyable. I have now modified the crankshaft to test this coming Sunday and that will likely be the finished product that will be up for sale by the New Year.
