STRICTLY OBSERVE THE FOLLOWING GUIDELINES IN ORDER TO USE THE PRODUCT PROP-
ERLY AND AVOID POTENTIALLY DANGEROUS ACCIDENTS.
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.
DISCLAIMER — PLEASE READ BEFORE PROCEEDING
Any modifications to a motorcycle’s exhaust or intake tract require carburetor re-jetting to
achieve maximum performance and maintain drivability. If you are uncomfortable with the
process of tuning your carburetor, we recommend that you bring your motorcycle to a qualified
motorcycle mechanic to have this kit installed. The jets included in this kit were selected based
on test results with various combinations of components that we felt would represent the
majority of the customers purchasing this kit (see Addendum I). However, no two motorcycles
are exactly alike. Depending on the individual case, additional jets may need to be purchased
from an outside source. Küryakyn warrants the parts included in this kit to be free of defects in
materials and workmanship, but makes no claim whatsoever in regard to costs associated with
installation or tuning.
WARNING! 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.
ATTENTION!
A factory service manual may 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 .
CAUTION! 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.
STEP 2
Remove the seat and rear-mounting bolt on the fuel tank.
STEP 3
Prop up the rear of the tank; a small block of wood works well.
STEP 4
Remove your stock air cleaner and spark plug covers. You may want to ask a
friend to hold and lift the tank slightly as you work the air box out from beneath,
slide it toward the rear of the bike and then out.
STEP 5
Remove the two hoses that are connected to the back of the air box. Take note of
the three hoses marked as “A”, “B”, and “C” in PIC.1. The hose marked as “A”
should be taken free of the metal retaining loop on the side of the carb. The
hose marked as “B” should be capped off using the included gray vinyl cap and the
hose marked as “C” should be routed up behind and over the top front side of the
carb. See PIC.2. Be careful not to kink the hose.
STEP 6
Remove and set aside the two bolts marked as “D” in PIC.2. They will be reused.
STEP 7 Re-jet carburetor. Refer to factory service manual for disassembly procedure and
to Addendum I for baseline jetting recommendations.
STEP 8 Cut the vacuum hose located on the upper right side of the carburetor and install
the supplied “T” fitting. Cut a 9-inch length from the vacuum line supplied in the
kit and connect it to the open leg of the “T”. See PIC.3. The other end of this hose
will be connected to the Hypercharger later.
