STEP 1
Read and understand all steps in the instructions before starting the installation. Park the
motorcycle on a hard, level surface and turn off the ignition. Let cool.
YOU WILL BE WORKING AROUND THE ENGINE AND EXHAUST SYSTEM
DURING INSTALLATION. ENSURE THAT THE ENGINE AND EXHAUST
SYSTEM HAVE FULLY COOLED TO PREVENT INJURY.
A FACTORY SERVICE MANUAL WILL BE HELPFUL IN PERFORMING THIS
INSTALLATION. DO NOT ATTEMPT TO PERFORM THIS INSTALLATION IF
YOU ARE NOT CONFIDENT IN YOUR ABILITY TO COMPLETE ALL OF THE
STEPS IN THE PROCEDURE; CONSULT A TRAINED TECHNICIAN.
IMPROPER INSTALLATION COULD RESULT IN SERIOUS INJURY OR
DEATH.
Installation of this kit
REQUIRES carb re-jetting over and above what may have
already been performed for pipe installation. This is a complex procedure and we
strongly recommend that this be performed by your dealer or a competent
mechanic. If you choose to attempt this on your own, you will need the service
manual for this model as carb removal and disassembly instructions are not
provided in this literature. THE FOLLOWING JETTING RECOMMENDATIONS ARE
INTENDED AS A STARTING POINT. Optimal performance and driveability may
require fine tuning. Adjustments may be needed for higher altitudes. General rule
of thumb is one jet size smaller for every 3000-4000 feet of elevation.
Rejetting and tuning a motorcycle can be a complex task. Due to factors outside of
our control, Küryakyn will not be held liable for any labor costs incurred from
installation of this kit.

The installation of any high performance exhaust system can cause a
“lean” fuel/air mixture. A “lean” fuel/air mixture can cause engine
overheating resulting in severe engine damage. Küryakyn
recommends rejetting carbureted bikes.
