SOURCE: installing oem carb need to see diagra on line

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part and/or the notation "Not Available" is in the description, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

Also, go to this site and you can download a free PDF service manual.
www.carlsalter.com/motorcycle-manuals.asp Most all of the manuals are in English but some are not. There is no way to be sure without doing the download. You can always delete it if in a foreign language. There are two listing for the 750. Even if the trim package is different, the carbs should be the same even if the years are not exact. The site may take 15 to 20 seconds to fill in with the manual listing.
Can I get a “very helpful” rating on this answer?

SOURCE: 2003 honda shadow spirit vt750 carbs

It is different then most other carbs. DON"T DRILL ANY BRASS HEADS LOOKING FOR THE AIR FUEL MIXTURE. The air fuel mixture is the only adjustment you can make. It is located on the bottom side of the air intake, right behind the air filter box. It looks like a 1/4" flat metal plug. Do NOT drill this. There is no slot for a screw driver. There is a tool which is no more then a small piece of pipe that fits over this plug and you turn it in till seated, gently. Count the turns. Back out to 2 and a half turns, thats normal. Or if you no that you need more fuel injected, simply turn the screw OUT 1/4 or 1/2 turn and try it. GOOD LUCK (Its not hard)
There is no drilling to be done. Hope i didnt scew something up on mine......

It sounds like you may have or will be jetting your carbs. I did this using the directions with the kit and used the Clyman manual for this bike to show me step by step how to remove the carborator. You will only need to attach 2 of the 4 hoses on your carb. syncronizer. If I remember right, you need to remove the bolt-on cooling fins to expose the engine block. The is a black screw or bolt that you take out and screw the threaded metal adapter of the sync tool. Be careful using the sync tool. Be very light on the throttle or the vacuum in the cylinder will **** in the mercury from the sync tool - not good. The problem you are stating on idle & backing off sometimes happens when the carbs are running rich (too much fuel) Hope that gets you in the right direction.

SOURCE: where exactliy is located the air-fuel mixture

The pilot air screws are sealed to prevent tampering. If access is necessary, the plugs can be removed. The Clymer manual, number 314-3, gives a detailed procedure, with pictures. Be careful! This requires skill with a drill in a small space, and it is possible to destroy a carburetor with poor technique.
Good Luck!

2003 Honda VT 750 C2 Shadow carburetor adjustment

Let's focus on adjusting the air/fuel mixture. This adjustment can help balance the fuel-to-air ratio for both cylinders. Here are the steps you can follow:

Idle Screw (Air/Fuel Mix):
The idle screw, also known as the pilot screw, adjusts the air/fuel mixture at idle. It affects the fuel flow from the pilot jets (idle jets) into the carburetors.
Locate the idle screw on your carburetor. It's usually a small black knob near the choke.
Turn the idle screw to achieve the desired idle speed. Listen to how the bike sounds while adjusting it.
Note: Adjusting the idle screw shouldn't significantly affect the mixture setting.

Pilot Screw (Idle Mixture):
The pilot screw (idle mixture screw) fine-tunes the air/fuel mixture from idle rpm up to about 1/8th throttle.
To access the pilot screws, you may need to remove the air box and carb side cover.
The factory default setting for the pilot screws is typically 2.5 turns out.
Carefully screw each one in until it lightly seats closed, and then count the number of turns.
You can adjust the pilot screws to make the mixture richer (more turns out) or leaner (less than 2.5 turns).

Dual Carburetor Sync:
Since your bike has dual carburetors, it's essential to ensure they are synchronized.
Use a vacuum gauge set to synchronize the carbs. Adjust the linkage screw until both throttle butterflies are in the same position for idle2.
Synchronization helps maintain consistent performance between the front and rear cylinders.

Check Rear Cylinder Idle:
If the rear cylinder isn't running correctly at idle, it could be due to a partially plugged idle jet.

Consider cleaning the carburetors if needed. While it can be a bit of work, it's essential for proper performance.
If the issue persists, consult a mechanic or consider opening up the carburetor for a thorough inspection.

Remember to take your time and make gradual adjustments. If you're unsure, consult your bike's service manual or seek professional assistance.
