Notes: Discoloration (known as "blueing") is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. This is not caused by a manufacturer defect. Biker's Choice offers products that will help prevent or remove discoloration. Reference National Cycle's Chemical section. For any bikes with modified or performance exhaust systems, National Cycle recommends a high-performance air filter and a fuel controller for fuel injected bikes, or jet kits and / or carburetors for carbureted bikes. This is for increased satisfaction in power, fuel mileage and "rideability". Use of any modified exhaust may not meet Federal EPA emissions and noise standards.
