  • Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the manufacturer directly with questions regarding any modifications that may need to be made during, or after installing their product. If a jet kit or EFI controller is recommended please see the Intake/Fuel section for products available
