A few years back I had a bike dyno tuned. Unless you were full throttle the bike was a nightmare to ride. Trying to cruise in traffic at 1/8 throttle just resulted in a boat of bucking and stumbling. Took it back to the shop. Guy put it on the dyno in front of me and claimed it ran fine. He would not ride it. It took me 12 hours of juggling needles/jets and just general screwing with it. Took it back to the shop and ran it on the dyno again, only cost 2 hp on the top but had a much broader, smooth power curve. Take a dyno for what it is, a number. I do not think there is any replacement for real world tuning. Just my opinon of course.....
