Up Hill Battle & Wheelies

I was taught that for every increase of 1,000ft in elevation a normally aspirated engine decreases 3% in horsepower


2014 CB1100 DLX
2013 CB1100 Std
1990 BMW K75 RT

That's a good approximation. If Ridem took his re-flashed bike to a dyno at 5000ft he would be pulling about 6-10% less power. About, and I say about because that 3% figure is more applicable to carbureted engines, what us ordinary mortals get at S/L.
