The air/fuel mixture screw on a Suzuki VS800 Intruder is typically located on the carburetor. To adjust the air/fuel mixture, you'll need to locate the carburetor and look for a small screw that can be turned.
Keep in mind that the exact location of the screw may vary slightly depending on the model year and specific carburetor version on your VS800 Intruder. Generally, it is located on the bottom or side of the carburetor.
Here are the general steps to locate and adjust the air/fuel mixture screw:
1. Locate the Carburetor: The carburetor is usually positioned on the side or underside of the engine. Follow the intake manifold or air filter housing to find the carburetor.
2. Identify the Air/Fuel Screw: Look for a small screw on the carburetor. This screw is typically flat-headed and may be recessed. It is often located near the bottom of the carburetor.
3.Adjustment: With the engine running at idle, use a screwdriver to turn the air/fuel mixture screw. Turning it clockwise (in) usually leans out the mixture, while turning it counterclockwise (out) enriches the mixture.
4. Listen to the Engine: As you make adjustments, listen to the engine's sound. The goal is to find the point where the engine runs smoothly and the idle is stable.
5. Fine-Tune: Make small adjustments and give the engine a moment to respond before making further changes. It's a process of trial and error to find the optimal setting.
6. Check the Owner's Manual: Refer to your motorcycle's owner's manual for specific guidance on the location and adjustment of the air/fuel mixture screw. The manual will provide information tailored to your bike's make and model.
If you're uncomfortable making these adjustments yourself or if you're unsure about the location of the screw, it's advisable to consult a professional mechanic or refer to the specific service manual for your Suzuki VS800 Intruder.

hi buddy the picture below will show you the mixture screw unscrew this 1/2 of turns out if still no difference unscrew another 1/2 if getting worse screw in 1/1/2 turns it just play with it budd this is the screw that puts the correct amount of fuel with the air
i'm not too familiar with dirtbikes but my experience with street bikes it has been on the underside of the carbs and if stock it is typically covered by a brass plug. this plug is just there to satisfy the epa you need to drill it out but be careful the screw is directly underneath the plug so as soon as you break thru pull back then use a screw to extract the plug. hope this is the answer you are looking for.
