Q:I have a 2014 Honda CB500F on which I put a Two Brothers slipon. Dividing the gallons used into the miles traveled comes out around 70 miles per gallon. That seems lean to me. Is there a way to enrich the fuel intake short of getting a Power Commander? I was hoping the onboard ECU would compensate for less backpressure.
A:The typical complaint we get is “my mileage is bad,” but now you complain “my mileage is too good.” Your ECU has compensated as much as it can. If you haven’t noticed any drivability issues, you’re golden. If you want to make it the best it can be, a Power Commander dyno session is the next step.
