The rights conferred by this warranty are exercisable only by the original retail purchaser of the product(s) returned as defective, and are not transferable to any successor, owner or other party.
Is exhaust bluing a warrantable condition?
No. All chrome plated steel exhaust pipes or mufflers will “blue” or discolor when the surface temperature reaches 900°F. This can occur if the fuel mixture is too rich. Instead of the charge burning mostly in the combustion chamber, the mixture continues to burn after the exhaust valve opens, down the pipe, causing extreme heat and bluing of the metal and its plated surface in the most restrictive areas – most commonly the bends or the baffle area. Cleaning products, such as Blue Buster™, are available and when properly used are quite effective in removing most discoloration from pipes.
Is re-jetting necessary to install Khrome Werks AR® exhaust systems?
Many customers think a richer main jet is required when changing to high performance pipes and/or free flowing air cleaner. Air/fuel mixture ratios taken during dyno and road tests of our HP-Plus Mufflers and AR systems on stock Harley-Davidson® models with free-flowing air cleaners showed no main jet changes were required to obtain desired performance and mixtures. But many required to be richer at idle and just off idle. The idle mixture screw should be set at 1/2-1 1/2 turns. A simple way to enrichen the off idle mixture on CV carbs is to raise the needle .030”-.040” with a washer or replace the needle with H-D part no 27094-88. If still too lean replace the slow jet with one size larger. Bikes with cams, high compression pistons, big bore kits etc. will require adjustments to all carb jets.
My bike backfires during de-acceleration after I installed aftermarket mufflers. Can the backfiring be minimized or eliminated?
Backfiring (or more accurately “afterfire”) is caused by unburned fuel/air mixture being ignited by the heat of the muffler. When the throttle is closed during de-acceleration and the transmission is in gear, the engine continues to rotate at a faster rpm relative to the throttle position. As a result of this engine rotation, more air/fuel mix is pulled through the carburetor or injector throttle body (dependent upon it’s ECM program). This mixture can then build up in the hot muffler and ignite. The bang heard is the sound of this fuel igniting after the throttle has been closed while de-accelerating. There are several other factors involved such as; ambient temperature, fuel additives, carburetor settings, ECU programs, alcohol enriched fuels, etc. that may also contribute to the afterfire condition. Stock restrictive mufflers mask this condition. Aftermarket mufflers are more open and allow the “bang” to be more apparent. Some types of exhaust systems such as “True-Duals” on Harley-Davidson® motorcycles seem to magnify the effect. Engines with carburetors can usually be rejetted to minimize the afterfire effect. Minimizing the afterfire effect of fuel-injected bikes is dependent on the ability to reprogram their ECU’s.
