Here, Let me help you with your math...151(stock at Rear) + 20(HP gained by your mods) = 171 Even being generous, 171 is not near 200 HP at rear wheel. 171/200= .85 that leaves 15% short. to make it simple you go 85 mph, I go 100mph and I beat you every time no matter how far you want to go. However, I do appreciate the data you supplied...it tells a good story, you should read and study your info closer.
My mistake it should be 157 + 20 = 177 therefore 177/200 = .885 making you only 12% off. But even at 88.5 Vs 100...you still lose. In a sport decided by .001 seconds, being 12 % off will still put your bike on the trailer and you in the stands
