What is the ideal temp for top speed on an H2?

60F Too cold = wheel spin

80F Too hold - IAT's too high, heat soak


Is 70F the ideal temp?

I did a track day in 48* F with TC set to "1". I struggled with grip from the rear at the beginning of sessions but the front was fine. There's too many variables to really say for sure.

I also did a track day in 85* F weather and had no heat soak issues. But my bike seems to be an anomaly. It just doesn't run hot. I use C12 and kept my Ignition Timing stock at the time I flashed it.

Ideally, tuning should be done to accommodate different weather conditions. There's no 'one size fits all' solution when tuning. That's why race teams collect data for each track and for different times of the year.

If you want a happy medium, you have to tune conservatively and give up a few top end horsepower. There's no way around that.
