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.

Hello you have a heavily rusted fuel tank, i would suspect the fuel petcock is being restricted.
As for the fuel tank here is a link to a product to remove the rust from your tank.
I have used it and it gets rid of it excelent product.

In that case the jets or the valve from the bowl are clogged by gums. Take the carburetor out again, dismantle it completely, soak it in cleaning fluid then blast every jet and canalisation with compressed air. Put it back together, adjust it properly, (be very careful about the fuel level in the bowl) and try again. You should adjust the carburetors using a flow meter for best results. Also replace the air filter with a good quality one

dont forget to inspect your work before cranking it, perhaps you for got to turn the petcock switch back to on, to let fuel flow from the tank to the carb?

When you strip a set of carbs you should balance them after refitting. The kit isn't expensive and comes with instructions. It could be something as simple as the throttle cables are set up wrong(if one is opening first then the engine may work okay in 1st but bog when under greater load ie 2nd)

Floats are sticking in carbs and staying open which causes fuel to overflow.you can try tapping float bowls with screwdriver handle sometimes this will free up floats .If this dosen't work you have to remove and clean carbs.Good Luck

Cbr 600 f3 carb problem


Inside of the carb is an inlet valve. Works like a toilet, with a float rising as fuel enters the float chamber..

Yes, is can be dirt, or a sunk float( meaning float absorbed fuel, and now wants to sink).

You need to remove the carb, and open it up to resolve this issue.

98 CBR F3 doesn't stay running w/o choke on


There seems to be fuel starvation to the carbs.
Check the fuel filter and the petcock, not bad too to clean the carb/s.

Trouble removing carbs on 96 CBR 600 F3


Theres a big lip holding it. Make sure all cables and pipes/hoses are removed, spray with some WD40 or similar spray lube and then try prying it with something that won't damage the carbs or engine.

Bike wont turn over


I have a 1996 cbr 600 f3 and when I first bought it used it would not turn over for the life of it. It turned out that a major problem was the spark plugs needing to be replaced. Thats the first thing to do. Next clean out those carbs with some good carb cleaner.
