To install this needle and jet kit: • Remove carburetors from the engine per Yamaha shop manual procedures. Note: Always perform internal carburetor work in a clean area. • Remove the vacuum slide from each carburetor. • Remove the OEM needle, spacer and washers, noting order of assembly. (Note; the washers are used as shims to raise the needle, each is equivalent to ½ clip position, use these to fine tune the needle) • Counting from the top to the bottom, install the new Baron needle clip on groove #4 of the replacement Baron adjustable needles. The top is the blunt end of the needle. • Reinstall the OEM spacer and washers as shown in the figure below. • Reinstall the vacuum slides along with the diaphragm spring and reattach the diaphragm covers. • Drain the fuel from the float bowls and remove the bowl covers. • Remove the OEM main jets and replace them with Baron’s supplied Mikuni main jets. Install the “base setting” main jets as indicated above. NOTE: V-Star 1100 carburetion runs staggered jetting! Make sure the front cylinder’s carburetor gets the larger main jet (numerically), and the rear cylinder’s carburetor gets the smaller main jet. Important! Extra jets have been included in your kit.
