Thanks Guys after reading Basscliffs website I figured that the air jets are 170's so I will install the 170 mains and 170 air jet in the morning.

Here are the instructions for the Stage III #3103

STAGE THREE INSTRUCTIONS

1.

Remove the vacuum slides from the carbs. Remove the stock needles

and spacers, noting order of assembly (Fig.A). Using the drill bit provided

(DD #7/64) enlarge the slide lift holes (Fig. A).

Do not drill the needle

hole.

2.

Install the Dynojet needles on groove #3 from the top. Use all stock

spacers (Fig. A). Install the small Dynojet washers above the e-clip.

After installing the slides in the carbs be sure to check slide movement
manually.

3.

Remove the stock main jets and replace with the Dynojet main jets

provided. If you are running the stock exhaust install the DJ165 main jets.

If you are running an aftermarket exhaust or slip-ons with high flowing
baffles use the DJ170 main jets. Be sure that the jet you are changing is
the main jet.

4.

Locate the main air jet (Fig. C). Install the main air correctors

(DCO301) with flat end facing into the carbs. Lightly tap into place.

5.

Locate the fuel mixture plug (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.
Carefully turn the mixture screw clockwise until lightly seated, then back
out 2.5 turns.

1.) You only swap out the MJ with the DJ 170 MJ

2.) You plug the stock MAJ with the DC0301 air corrector. You DO NOT swap out the MAJ.
