completely stock bike-42mpg. after pc3-44mpg. after my other mods-38mpg. of course everybodies will be different due to location, riding styles & how wrist heavy they r. if i took it easy i could probably get 40mpgDid you have a change in fuel economy? I would expect a drop due to the increased fuel, but interested if its enough to even notice.
Keeping on topic, I have slip ons on a 2011 Z. I get a "just barely on the throttle" exhaust flutter, I presume is just louder now thanks to lessened noise reduction.
Is that something done away with using a PC?
