Ok which jet is which?

[butticci]

I have taken the carbs apart at least a dozen times and I know where all the jets are but Im confused. I bought a stage 1&3 jet kit and was wondering if the 118 is the main jet for stage three? That seems a little small to me. I have four 118, four 114, four 165 and four 170. Some air jets and needles. I have a gs1100g with pods and a four into one. other than that the only mods are a dyna ignition and paint. What should I start with Main jets and needles? The PO had the 170's in the back of the carb (I guess this is a air jet) and the 118's in the main jet is this right for a stage three. I was thinking around 122.5 for the mains? Oh yea should I drill out the slide lift hole or not?

I would have suggested you put in the 170main jets, but since you have new paint I will need to know what color it is? Any pin stripping? :-\\\

Electric Blue debating on white pintriping! So the 170's should go in the main jet. It seems I have two air jets one is for the pilot (small one) and one ist for the main air (big one) is that right? What should my main air be? Currently the main air is 170 and the main jet is 118 do I have those backwards? Oh yea Thank Yous to all this site is Heaven Sent!

Did you see the 3103 directions?

DCO301 is the Main Air Jet

170's are the Main Jet with pods/pipe (Stage III)

Tap in the main air jet corrector.
I'd start with the 170s
Start with the needle jet on a notch one below the suggested spot. (raising hence richening)

He'll look like a lightening bolt at midnight as he zooms by.

Sorry guys I have been doing homework! BORing. OK so what is the big jet in the intake port? Thats the one I have the 170's in now. I am waiting on my petcock rebuild kit or I could give you an update should be here by monday.

 

[butticci]

Oh Yea! As for drilling the slides is that really needed?

With the pods, Yes

 

[butticci]

I swear Im not trying to be a pain in the arse but what size should the big jet be that is screwed into the intake side of the carb?

Jet on the intake side of the carb?

 

[butticci]

The part that I am talking about has two jets and a passage that leads to the slide diaphram. I was told that the small jet is the pilot air jet and the big jet which is the same size as the main jet (physicly not in orafice size) is the main air jet. Is this correct? One of these jets screws out just like the main fuel jet. The other is tiny.

 

[Guest]

Use the stock pilot air jet.
Do not put the 170 main air jet in that hole. This goes in the float bowl.
Look at the neato pictures in your dynojet instructions and follow them.

 

[butticci]

On the DynoJet instructions Fig C refers to the the pilot air screw I understand that but the other jet in that illustration is suppose to be what size and what is it called?

 

[butticci]

So what size is the other jet suppose to be?

 

[butticci]

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.​
