STAGE ONE INSTRUCTIONS

1. Remove vacuum slide from carb. Remove stock needle & spacers, noting order of assembly (Fig.A).

2. Locate the slide lift hole (Fig. A). Use the (DD 55) drill provided to enlarge the small slide lift hole (Fig. A).

3. Install the Dynojet needle on groove #3 for applications below 5000 feet, groove #2 for above 5000 feet,

using all stock spacers (Fig.A). NOTE: The DSP77 spring does not have to be used, it is supplied in case the

stock spring is misplaced. The Dynojet washer (DW0001) does not need to be installed at this time, it is for

half step adjustments. After installing the slides in the carbs, be sure to check slide movement manually before

airbox installation.

4. Remove stock main jet and replace with Dynojet main jet provided. Use the DJ128 below 3000 feet, DJ124

from 3000 to 6000 feet and DJ120 above 6000 feet. When using an aftermarket exhaust with a high flow

baffle, use the DJ132 below 3000 feet, DJ128 from 3000 to 6000 feet and the DJ124 above 6000 feet.

5. Locate the Fuel Mixture Screw (Fig.B). Using a flat blade screwdriver, turn the mixture screw clockwise until

it seats, then turn out 2.5 turns, 2 turns above 5000 feet.
