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......

Be sure to properly oil the K&N filter after you've cleaned it. Then verify that the jetting is correct by operating at full throttle (only for as long as safe conditions will allow) then stop the engine and look at the color of the spark plugs. White coloration of the plugs = too lean. Dark spark plugs = too rich. A nice tan or light brown color = perfect.
Running with jetting that's too rich, or too lean, can both cause driveability problems, poor performance and reduced spark plug life.
While you're in there, inspect the spark plug caps for damage, cracking, and signs of electrical 'leakage' (carbon tracking which are conductive, visible lines running down the length of the cap, inside or out). Replace any plug caps that look suspicious. Tip: WD-40 works as a great, non conductive cleaner for plug caps and high tension leads.

SOURCE: Carbs sputtering and misfireing on Shadow Spirit VT750 2005

An engine never misfires due to these things. It is always because of maladjustment of the timing at the CB points. Check the timing and set it right.

2005 Honda Shadow Spirit (750) hesitant and sputtering upon first spring ride. Thoughts?


Just sounds like either a jet is blocked in one of the carbs or maybe a spark plug is fouled up.tap the exhaust down pipes with your hand quickly to see which one isn't getting hot to see which ones not running.

Bike stalls after running for 15 minutes or more


sounds like you have a vacuum issue. tank isn't venting. run the unit with the gas cap off and see if it still has the issue.

2002 Shadow: bike leaks gas from the carb, and runs with no gas going to it


Carbs have a reservoir in the base that will last for a few miles before it is drained. So turning the fuel off doesn't starve the engine immediately. This is normal.

I have a 03 Honda spirit 750 --was riding yesterday when it started spiting/sputtering like it was out of fuel, I checked fuel(half tank) I put another gallon in just to be sure but no luck. Also tried...


Drain the carbs. Water condensation in the gas tank makes it's way into the carb float bowl. After a while the water builds up enough to replace gas in the carbs. Bikes don't run well on water. If that doesn't work at least no money has been spent. Next, stick in fresh spark plugs and be sure the air filter is clean.

Run some carburetor cleaner through the system to remove any dirt which may be interfering with the carb diapharms............Let idle for 15 to 20 min before trying acceleration.........Hope this helps you out.

Fueling problems with my honda shadow 750


My Shadow does this as well, and I've read on some of the Shadow forums that other people have noticed this with their bikes too, so I don't think it's a "problem" so much as poor tank design.

Honda Shadow 750: When driving the speedometer will shut off along with the digital mile counter. At low speeds it will also sputter when this happens


I'm not personally intimate with the Shadow, but on most motorcycles this is generally indicative of charging system issues. You may have lost a phase in either the stator and/or regulator.
Measure the voltage across the battery with engine running and ensure you have better than 13.5V.
If not that will confirm that your charging system needs to be further investigated.
