Lots of talk about changing exhaust systems, shimming the carb needles, modifying the air box, and installing different air filters (and enhancing the fuel injection systems on fuel injected bikes). But so little data…

Has anyone on this forum done any of the above modifications using a dynamometer to maximize (and document) the performance (power and torque) increases? Or know someone who has?

How many hours of dynamometer (and shop) time did it take?
How much was gained? (Before and after power and torque versus RPM curves, if you've got 'em).
How much did it cost?

I’m especially interested how this has worked out for the Ninjettes, but please share experiences with other bikes as well.
