After installation and before starting the motorcycle, completelyclean pipes and mufflers with cleaning solvent and aclean soft cloth that will not leave residue.NOTE: Any residue, oil or fingerprints will stain the chromewhen the metal heats up.HELPFUL HINTS ABOUT EXHAUST CARE:1. When installing a new set of chrome pipes, make sure yourhands are clean and free of oil. After installation, thoroughlyclean pipes with a soft cloth and cleaning solvent that willleave no residue (chrome wax/polish, glass cleaner, alcohol,ammonia, etc.) before starting the motorcycle.2. Avoid long periods of idling as this can cause discoloration.DRAG SPECIALTIESPYTHON MAMBA DUALSP/N 1800-12043. Intake leaks can cause the engine to run lean and overheat;this could lead to discoloration.4. Make sure there are no exhaust leaks at the junction of theexhaust pipes and cylinder head. We recommend replacinggaskets if they are worn.PLEASE NOTE: Every effort is made for Python Exhaust Systemsto provide improved cornering clearance. However, dueto design and space limitations on some motorcycle models,ground and cornering clearance may not be improved and insome cases may be reduced. Be sure to follow proper installationinstructions.WARNING!: Before operating motorcycle, be sure all hardwareis tight.3501 Kennedy Rd, PO Box 5222, Janesville, WI 53547-5222REVISED 8/2010P/N 1800-1204Page 4 of 4
