I have Micron bolt-on AND K&N filter, and no jet kit. I did notice power difference, but that's about it. No negative effects except for fuel economy. I get about 40mpg (I do drive it hard for the most part, and I do have a -1 front sprocket which raises the rpms).Originally posted by johnnythrux
How many of you have rejetted when adding a slip-on? Has anyone noticed any negative effects from adding a slip-on without doing anything to the carbs?
