Gen 2 gas mileage

52 on gas, 48 if it has ethanol in it. Has not changed since new on my K9.

Those getting in the 20’s I wonder how much carbon buildup you have and how it affects your performance?

I purchased a used Gixxer 600 for the track, whith a pipe and a tune doing around 30mpg. All I did is opened the motor, took out a crap load of carbon, took it back to 100% stock. The power increase after that was unbelievable.
