Calibration runs: We did several runs when the bike was first put on the dyno. The run below - Run007 was determined to be the 'average' of these runs. The runs we used did not vary by more than instrument accuracy (less than 1HP) at engine speeds > 5.5 k, and less than 1.5HP below 5.5 k.
Figure 1, Calibration (Standard) Run

As can be seen by the plot above - the K100 engine exhibits a remarkably flat torque curve. The peak HP shown of 73 seems about right since it is 'rear-wheel' horsepower, and considering the transmission losses in the tranny and rear drive it would indicate approximately 90HP at the engine.
