you get into a higher gear on the dyno so that acceleration is slow enough to make get an accurate reading (you fly through 1st, 2nd, etc. and will take longer to get through the powerband in 4th,5th, etc.)That was an interesting dyno-run that that kid made. I preface the following by saying this first: I know next to nothing about running a dyno on a bike. My understanding is that the power delivery is always the same no matter what gear the bike is in. So when you measure the hp of a bike, you kind of want to take the engine through the tach in each gear to get an accurate reading. With that understanding, why did the kid shift the bike hard and keep the bike up high in the rev's like that just to do a dyno run? And yeah, why did the kid pull the clutch in at the end? Shouldn't he have let the engine slow down while it's still in gear instead of taking the load off of the engine all at once like that?
