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.
Some of our high performance air cleaners extend beyond the
stock/OEM unit to achieve smoother air flow and better performance.
Riding position may be affected, so it is important to familiarize
yourself with the new riding position.
Proper tuning is important. We recommend fuel injected bikes should
be tuned with a TTS MasterTune tuning system (calibrations available
at www.kuryakyn.com), or by an experienced tuner, on a dyno, with
an exhaust gas analyzer. 2007 and later Harley Twin Cams run
especially lean combined with retarded ignition timing. Lean
conditions and/or retarded ignition timing will cause high exhaust
temperatures and discolor chrome exhaust.
STEP 2
Remove the stock air cleaner so that the throttle body is completely exposed. Be
sure to scrape any gasket material that may be left on the throttle body flange.
STEP 3
As shown in PIC 1, install the breather bolts to the threaded holes in each cylinder.
Tighten
securely.
STEP 4
Install the straight fittings to the backing plate as shown in PIC 2, connect the
formed breather hoses to the straight fittings on the backing plate.
STEP 5
As shown in PIC 3, hold the flat Air Lock Ring in place against the throttle body
flange. Line up the holes from the air lock ring with the threaded holes in the
throttle body flange. The Air Lock Ring also acts as a gasket in this location, SO
NO OTHER GASKET IS USED.
STEP 6
Using the 1/4”-20 x 1" Socket Head Cap Screws, secure the backing plate to the
throttle body flange as shown in PIC 4. Be sure that the air lock ring is in place
between the backing plate and the throttle body flange. Tighten the hardware.
STEP 7
Snap the dual velocity ring in place. The ring should be positioned as shown in
PIC 5 with the open hole positioned in the 10 o'clock position.
STEP 8
As shown in PIC 6, connect the formed
breather hoses (installed in Step 4) to the
breather bolts installed in Step 2.
STEP 9
Install the air filter to the backing plate.
The air filters press on and should hold in
place.
