    Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturers directly with questions regarding any modification that may need to be made during, or after installing their product. If a jet kit or fuel processor is recommended, see the Intake/Fuel section

    Exhaust discoloration (bluing) is caused by engine conditions such as cam timing, fuel-air mixture, operating temperature, etc. It is not the result of defective manufacturing; therefore it is not covered by any warranty. See the Chems/Lubes section for products to help remove or prevent exhaust discoloration.
