SOURCE: Carbies willn't set float level,right floods,left sets to low

I don't know if its any help but I've fixed my Honda with similar problem. It turns out I reassembled the rich carbys air cut off valve incorrectly. Have you checked yours? I'm wondering if the cut off valves somehow affect the other parts of the carbys. Mine is running sweet now.

SOURCE: Which size Jet Kit for 800 Vulcan Classic?

general rule of thumb is to go up about 10 jet sizes,unfortunately it is a bit of trial and error,and you may have to swap out diferrent sizes to get the bike running right,(jets are quite cheap though)but first step about 10 sizes from standard,your local dealer should be able to tell you what jets are in it and supply replacements,if you change to a hgh flow aftermarket air filter you may have to change jet sizes again as changing the filter may effect the mixture ratio in the carbs,,hope this helps

SOURCE: how to adjust carby

The air fuel ratio: start with screw all the way in, not tight, Then back out 1.5 turns. Set your idle then readjust the a/f ratio to get best, then readjust your idle. good luck

SOURCE: backfiring through carby and exhaust

Sounds like the carby is flooding.

Have you had it off?

Try putting a new fuel shutoff valve and seat in.

Set the proper float level.

Make sure that the float does not have a hole in it that makes it sink.

Lindsey... your problem is the classic issue with plugged jets. Specifically the low speed speed (pilot) jets are clogged. With the carb removed and the float bowl removed, and the float also removed, you'll see generally two sets of jets. Usually the one in the center is the main jet and has a larger hole and that jet doesn't usually clog but to be sure remove it and inspect the opening. If you can't see light then it's clogged. The more suspect issue is the pilot (low speed jet), usually off to the side. This jet, once removed has a longer body and this is the jet that is clogged. Perform the same "look thru" and you'll see no light or very little. When this jet clogs it displays the symptoms you mention. As you give the bike throttle, transition from idle thru low speed and then to main jet occurs, based on rpm and throttle demand. The pilot jet doesn't allow transition and the bike falters from about 2000 to 5/6 k rpm.

So how to clean. I've tried acetylene torch tip cleaners but most are too big. If you have an air compressor, try blowing high pressure air thru the jet and it may clear. The ultimate fall back is a chemical clean. Place the jet in a ultrasonic tank or purchase Berryman's carb cleaner in a small tank (1 gallon) (Auto Zone or internet)http://www.amazon.com/Berryman-0996-Chem-Dip-Carburetor-Cleaner/dp/B00DSMEL2A/ref=sr_1_1?s=automotive&ie=UTF8&qid=1419804749&sr=1-1&keywords=berrymans+carb+cleaner
and soak the jets in it. Here's another potential problem... the pilot hole in the body of the carb may also be plugged so while at it disassemble the soft parts from the carb and treat the carb body (no soft parts) also in the carb cleaner. Usually about 1 - 2 hrs soak removes the clog. Best to clean all holes in the carb body with high-pressure air. Since you have a four cylinder then you must perform the same exercise 4x. This will solve your problem...

Good Luck... Dio

Why would I have to re jet my 2002 Yamaha vstar 1100 custom?


Hi, Anonymous if you have changed your fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel.
1. Closed to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

Go Cart. Starts and runs only on full choke. 4 cycle, gas. Open choke, and engine dies. Sat for over a year. New gas, throttle working, spark ok. Can't find any air leak; carb never off of engine.


Remove the carb, then the float bowl at the bottom of the carb then clean the carb with spray carb cleaner. Spray into each and every drill hole and jet you can find. Use goggles so you don't accidently get cleaner in your eyes. Please, rate my answer, thanks. Reset the air and throttle screws, one and one half turns outward from a lightly seated position. Please, rate my answer. Thanks.

Remove and clean the carburetor. The problem is a plugged or partially plugged idle jet. There should be a throttle screw and an air screw on the side of the carb. The big screw is the throttle screw. Remove both screws and the float bowl and spray carb cleaner in all the holes and screens and jets to clean out the plug. Use goggles to avoid spray kicking back into your eyes. Put the two screws back in the hole each one came from and then turn them clockwise ubtil they LIGHTLY seat. Now open each of them one and one half turns.

Check the condition of the fuel line from inside the tank to the carburetor. Check tightness of all screws on the carburetor body. If no help, disassemble the carburetor and check the condition of the pumper valves and diaphragms. If looks dirty, clean with spray carburetor cleaner and blow out with compressed air (don't use cleaner on any rubber or plastic parts). Remove the H and L needles for cleaning and air blast. Preset the needles 1-1/2 turns CCW from CW stops (lightly). If the rubber parts are stiff, re-kit the carburetor. After engine warm--up, set full throttle and adjust H for highest speed, but 4-stroking. It should run smoothly with a light load (cutting). Set L for smooth idle but rich enough to allow the engine to follow the throttle. Set idle speed just below chain movement. Hope this gets you going again.

Sounds like dirt in the main jet of the carb. Take the slide out and clean the needle. The pull the float bowl and blow air or carb cleaner through the brass jet in the middle of the barb, where the needle seats.

Vstar 650 classic. only will idle.


hello and welcome
this is a very very commom problem after the cycle has gone over a storage period of anything over a month or so. what has happened is the deteriorated fuel has plugged the idle jet, and possibley other jetting. this is verified by pulling out the choke allows it to run. because this makes of for the loss of fuel the jets are not produceing. so to fix this you will need to remove the carbs and take out the jets and clean them thoroughly with a carb cleaner and possibly a very small gauge wire to break up builup. especially in the pilot jet. unfortunately fuel added carb cleaners dont seem to work for this kind of problem and to fix right they should be disassembled and cleaned thoroughly. thank you.
