• From idle to 1/8 throttle is controlled by the idle mixture screw
• Just off idle to 1/4 throttle is controlled by the low speed jet
• 1/4 throttle to 3/4 throttle is controlled by the needle and needle jet
• 3/4 throttle to wide open is controlled by the main jet
STEP 12 Reinstall the carb on the manifold, and re-connect all hoses, cables etc. Tighten
the intake manifold clamp.
STEP 13 Reinstall the stock carb support bracket.
STEP 14 Install the billet aluminum carburetor adapter on the mouth of the carburetor. The
adapter’s slot should be in the 3 o’clock position with the pinch bolt installed from
the top. Do not tighten the pinch bolt at this time. Install the peel and stick gasket
to the exposed surface of the adapter.
STEP 15
Install the chrome carb support bracket using the M6-1.0 x 15mm hex head cap
screws provided. (PIC.6). If there is a gap between the stock air cleaner mounting
bracket and the new carb support, shim with the supplied 1/4” flat washers. In
some cases it may be necessary to slightly bend the stock bracket so the carb
support will lay flat against the adapter when the M6 screws are tightened.
STEP 16
Install the 1/8” NPT x 3/8” O.D. nipple in the threaded hole in the bottom of the
breather adapter.
STEP 17 Remove the trap door from the front with a 1/8” hex key, remove the trap door on
the front of the Hypercharger. Install the Hypercharger and breather adapter as
one unit. The three 1/4”–20 x 2” socket head cap screws will go through the back
of the Hypercharger, the breather adapter, and the carb support then thread into
the carb adapter. Be sure to install gaskets between the Hypercharger and
breather adapter and the breather adapter and support bracket. The breather
nipple should point downward. Note that one of the four holes in the Hypercharger
will not be used - it is a vent hole for H-D applications. See PIC.7 (In PIC.7 we
have removed the front of the Hypercharger and the filter for clarity. You need
only remove the trap door.) Adjust the Hypercharger so it is horizontal before
tightening the 1/4”–20 x 2” screws. Reinstall the trap door and securely tighten
the adapter pinch bolt.
STEP 18
Insert the 3/8” barbed connector into the breather hose (PIC.3) and add the 6”
length of 3/8” I.D. hose included in the kit. Plug the extended breather hose onto
the breather adapter’s nipple. Secure all connections with the hose clamps provided (PIC.8).
STEP 19
VERY IMPORTANT! Install the plastic 90° elbow in the threaded hole on the back of the
Hypercharger. The stock float bowl vent hose is routed from the carb back to a “dead end”
location under the seat. Pull this hose free from under the seat, but leave it connected to the carb
fitting. Run this hose from the carb down to the 90° fitting on the back of the Hypercharger, cut it
to length, and connect it to the fitting. See PIC.9.
STEP 20
See PIC.10. Locate the vacuum line going to the fuel petcock. At a convenient location, cut the
line and install the “T” as shown. Install the supplied length of vacuum hose to the “T” and
connect the remaining end to the vacuum nipple on the bottom of the Hypercharger. (The
butterflies will be wide open when the bike is off, or at full throttle, and mostly closed when the
bike is at idle.
STEP 21
Re-install the tank, dash, and seat in the same manner it was removed.
STEP 22 Double check the tightness of all related fasteners, check for hose clearance and check
throttle for correct operation, making sure it returns properly, before starting the bike.
ATTENTION! It is the installer’s responsibility to ensure that all of the fasteners (including
preassembled) are tightened before operation of the motorcycle. Küryakyn will not
warranty components lost due to improper installation. Periodic maintenance may be
required.
