[QUOTE="reepicheep, post: 1360681, member: 104942"] Nice to see people getting it right here. Motorcycle forums seem to always get it backwards, and think that torque is the important part, and it's irrelevant without RPM, and when you multiply torque times RPM (and a constant) it is Horsepower... That being said, HP changes with RPM, and in most cases, its climbing as rev's rise. So keeping speed constant (pick 15mph or something), and gearing down, can actually increase horsepower. You are still going 15 mph, but you are revving the motor more to do it, and so generating more available HP. Until you run out of revs, then the power drops off and you have to shift. You haven't changed the peak HP the engine can deliver, but you have changed your revs at a given speed to be higher, and potentially put yourself closer to that peak HP capability. Of course, as this is a two stroke, you may also have moved it further away from that peak HP capability. When I get mine running, I ought to drop the $50 for a few real honest to God dyno runs... Maybe before and after with the Boyesens that were generously sent to me... Dyno plots for these things are pretty hard to scare up, I could only find one with a lot of googling. [/QUOTE]
