Has anyone ever seen Dyno data showing the effect of heat on performance on M8's? I know that the ECM retards the timing when the heads cross 250 degrees which is fairly common on trikes during the summer. I'd love to see what my stock engine is really doing once it reaches 270 and 290 degrees, and if it stays fairly flat after going into the retard mode or falls like a rock..... or maybe it's better not to know. I'm sure that's what HD is thinking.
