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.
NOTE: This installation requires re-jetting of the carburetors. This is an involved
procedure that we recommend be performed by a qualified service
technician. If you choose to attempt this procedure yourself, refer to the
carburetor removal, disassembly, reassembly, and installation procedures
outlined in your V-Star service manual.
STEP 2 Remove the driver and passenger seats from the bike. Remove the negative
battery cable from the battery and tuck it out of the way to reduce the possibility
of sparks.
STEP 3
Remove the two, rear tank mounting bolts. Remove the plastic tank mounting
snap stud. (Push in on the center of it to release). Slide the tank back to expose
the top of the engine. Make sure the tank is secured so it does not fall! You may
remove the tank completely if so desired.
STEP 4
Remove the stock air cleaner cover, element, and backing plate. The top and rear
mounts are secured with screws, the front mount “snaps” into a grommet.
STEP 5
See PIC.1 and PIC.2. Remove the grommet from the bracket.
STEP 6
Placing your long handled Phillips screwdriver as shown in PIC.3, loosen the clamp
on the air duct and remove the duct. Remove the clamp from the duct and set it
aside, as it will be reused.
NOTE: Now is a good time to proceed with re-jetting of the carburetors. Consult
your factory service manual for this procedure. We have supplied jets to
cover most common applications.
