Tip: Always have a factory service manual handy for reference. |
|
Remove the seat, side panels and fuel tank. |
|
Remove the air box lid, air filter, then the complete air box from the carburetors. |
|
Loosen the intake manifold clamps and remove the carbs from the manifolds. This can be done by unplugging the four wire connectors, removing the one lower fuel line and disconnecting the choke cable. |
|
Lay rags over the intake ports and a towel on the engine. Turn the carbs on end as shown and use a bungee cord to help hold them in this position. Removing the float bowls is not necessary. Dale was experimenting with jetting when this photo was taken. |

This is the pilot fuel adjustment screw that is covered by a pressed
in plug. This located in the tower shaped casting sticking down out of
the carburetor. To remove it, carefully drill out the plug with a new
1/8" drill bit. Be sure not to drill any further than the plug, which
could damage the adjustment screws. Once drilled screw a 1" long #8 pan
head sheet metal screw into the plug, grab the screw
head with vise grips and carefully twist out the plug. Blow out any
chips, being careful not to let them get into the carbs.
With the plugs removed turn the fuel screws gently clockwise until they bottom, then back out 2 full turns. This is my base setting and the adjustment window is 2 to 3 turns. In is leaner and out is richer. This will mostly effect the idle, off idle and mid range performance. Note: Do not remove the float bowls! Dale was experimenting with jetting when this photo was taken. |

Remove all four carb tops one at a time. Remove the needle assembly
from the slide and add two Holeshot mill spec stainless shims to the needle
as shown per my base setting. Only one shim is shown in this
example photo. One shim will be slightly leaner while two or three
is a richer mixture setting. This will effect the mid range roll-on,
steady cruise and top end power.
Note: Changing jets is not needed to achieve good performance gains and overall smooth running with our slip-ons installed. |
|
Carefully reinstall the slide diaphragms making sure they are
properly seated in the retaining groove of the carburetor body.
Note: Be sure the brass insert is properly located and seated in the carb body. Install the diaphragm springs and all four carb tops. Carefully reassemble the bike in the reverse order of disassembly. Fire up the motor and let it warm up fully, then set the idle at 1000 to 1200 rpm. Now go test ride and enjoy your new smoother running and much faster ZZR-1200 with your new Holeshot slip-ons and simple carb tweak. Please let us know how you like your Holeshot ZZR slip-ons and simple carb tweak by dropping Dale a note here. |
