Question about 2001 Honda Vigor FX 650

Open Question

After starting my FX650 I need to use the choke very,very long.

Still after a ride of 4 km it can not idle without 1/2 choke.
Is that normal for FX650? After another 5 min. idling on 1/2 choke it will idle without choke at 1500 revs.
What must be the size of the pilot jet?
What must be the liquid level in the floatchamber?
What must be the position of the airscrew?
Where can I buy a workshopmanual?
Thank you in advance for your help,
Best regards, Bram Hartman, The Netherlands.

SOURCE: cbr 125 choke problem

It sounds like the choke line may not have been routed correctly when the new one was installed. Remove the gas tank and check to see that the line is not being stretched anywhere along the way AND that the gas tank when re-installed is not stretching the line. The line may have been kinked when installed. Look at the mechanical movement of the choke at the carb. Does it operate freely? Remove the air filter and look inside the center of the carb, (you may need to use a small mirror for this), does it look like the choke is opening and closing properly when the choke is moved on and off?

SOURCE: honda vfr 400 does not idle

gummed up carbs, faulty fuel pump, blocked fuel filter.

all of these will give you that response, fuel starvation.
you are not getting the right amount of gas thru, unles you have the choke on which cuts out some of the air making your mixture a little richer.

if it sat over winter in storage, the carbs probably could do with cleaning. you can try removing the air filter and spraying a bunch in, let it sit over night and see what happens. a good fuel system cleaner (additive) may help. if you can get Berrymans B12 ( dont know what country you in) it may be just american. but if you get some double the dose throw it in the gas tank, run bike til hot and then put it away for the night. then next day hopfully should be better. also if you have an inline fuel filter you could try changing that. does it have an electronic fuel pump.? does it run constantly? http://www.carlsalter.com/motorcycle-manuals.asp

First Make sure you have all new fresh gas,and new fuel filter,Then check the intake tube between the head and carb for cracks or leaks,And You'll need to go back through the carb again as this is a carb issue,But without doing the above first,a clean carb won't be clean for long.

SOURCE: Honda shadow ACE 750 dies on idle after warmed up

I guess you will have to reset the air-mixture screws of the carburator/s.
Not bad if you check the condition of the spark plugs...if its ..'Whitish' means lean i.e. less gas in, Brownish...means ok, 'Blackish'...means too much gas in .....'rich'
In your bike's case you may find it 'whitish'.
Hope this helps !

Hi, Andrew and the usual suspects are:

1. Fuel cap or fuel tank is not venting properly.

2. Fuel filter clogged.

3. Fuel line pinched or kinked.

4. Float needle and seat sticking.

5. Float level too low.

6. Carburetor bowl vent line clogged/blocked/pinched.

7. Idle adjusting screw set too low.

8. Air/fuel mixture screw set too lean.

9. Idle port, transfer ports, slow air jet clogged.

10. Slow fuel jet clogged.

I have a 2005 harley davidson sportster xl 1200 custom. after bike is at normal operating temp.when i stop for redlight or stop sign, bike idles to fast.i can let out on clutch little bit and it will slow...


If the carb is adjusted correctly, the engine will not idle without the choke when cold. I will usually take at least 3 to 5 miles of riding to get the engine warm enough to idle by itself without the choke. If your bike is a full operating temperature, it should idle at about 1000 RPM. If it's idling higher than this, you need to slow it down a bit.

Remove the air filter cover and look at the top right side of the carb. You'll see a screw there . This is the throttle stop screw. Turn the screw counterclockwise to lower the idle speed to 1000 RPM or so. Blip the throttle and let it settle back to idle. Reset it if necessary. Once set, put the air cleaner cover hand on.

Vmax will start and barely run only under full choke


If it can idle then still hope to help out else need to rebuild/clean carb out (cost a lot). If can idle then get yourself 2 bottles of fuel injector cleaners, pour 30ml to 5L fuel, let engine idle for 15 minutes, give some spur high3000 - 5000 RPM revs followed by a constant 3500 RPM rev for 15 sec then repeat process again another 3 times. Ride itnormally as if you are breaking it in until next time refuelling, add another 30ml and do the same process before riding it again. Do the same thing for the next 500 km.

Cannot start not using the choke and rpm flattens at 4000 rpm


The air screw and the idle screw turn inward until they LIGHTLY seat, then back out one and one half turns. For the dead spot, pull the slide out of the carb and move the clip on the jet needle down one notch. Two notches if needed.

The pilot jet covers the idle function. It sounds like this is not the problem though. The high idle indicates a lean fuel mix. An air leak is leaning the mix. It could be bad intake manifold gaskets, carb and manifold not down tight, loose spark plug, cylinder head not tight, bad head gasket.

If you do want to adjust the pilot jet the, often it is adjustable from the outside of the carb. It is normally located just out side and next to the main jet. It will be brass and have a slot for a small screw driver. If no outside screw, then an inside adjustment screw means removing the float bowl. Turn the jet screw outward 1/4 to 1/2 turn.
