STAGE ONE INSTRUCTIONS
1. Remove vacuum slide from the carb. Remove stock needles & spacers, noting order of assembly (Fig. A).
2. Install Dynojet needle on groove #2 for applications below 3000 feet, groove #1 for above 3000 feet, using
all stock spacers. Install the Dynojet washer above the E-clip.
3. Install the Dynojet slide spring (DSP007M) in-place of the stock slide spring.
4. Remove stock main jet and replace with Dynojet main jet provided. If you are running the stock exhaust
use the DJ160 below 3000 feet, DJ155 from 3000 to 6000 feet and DJ150 above 6000 feet. If you are
running an aftermarket exhaust, use the DJ165 below 3000 feet, DJ160 from 3000 to 6000 feet and DJ155
above 6000 feet. Be sure that the jet you are changing is the main jet.
5. Locate the Fuel Mixture Screw (Fig.B). If you see a screw head at Fig. B then proceed to the adjusting
procedure. With the 5/32 drill bit provided carefully drill through the plug. NOTE: The mixture screw is
directly underneath this plug, be ready to pull back on the drill the instant you break through. Use screw
provided to secure and remove this plug. Using a flat blade screwdriver, turn the mixture screw clockwise
until it seats, then turn out 3 turns below 3000 feet or 2.5 turns above 3000 feet.
