Question about 2003 Honda VT 1100 C Shadow Spirit
Hi, Cberkheimer if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will not idle unless the choke is full on and run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition and in the future pour in a bottle of fuel stabilizer and injector cleaner for you FI folks at least 2 times a year and before storage.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or more, any readings in the 11 volt range you need to do a proper "LOAD" test on the battery and replace as necessary, you may have 12.5 volts or better but little or zero amps, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank if it rusty there is a cheap and easy fix. https://www.youtube.com/watch?v=fUYr_7SwGms
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a "CARB DIP" or if you have EFI remove injectors and clean with carb spray and compressed air
7. Check intake manifold and seals for leaks and cracks.
8. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
9. Replace spark plugs with new ones and check for spark.

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

You sound like you have a blocked idle jet in the carb. Honda trail bikes love new oil, clean air cleaners and clean fuel. After a while a build up of tannins and crusty residue will invade the carby bowl and usually migrate through the carb via the jets and the emulsion tube where the jet needle runs. The easiest way to fix your problem is to remove the carb and go through it. Clean all jets and check float height and generally get it back to scratch. You will have to re- adjust your idle and mixture settings after you have fited it back to the bike. If you are not Mechanicaly savi then I would suggest you take the bike in to your local honda dealer and get them to go through the carb for you.. It's not a big problem and is easlily fixed.
Hope this helps...

Your carb. is dirty. Use a varb. cleaner gasoline additive such as seafoam. If you use that product, from most auto parts stores, you add one ounce per gallon of gas.
Also, change the spark plug. If these steps don't solve the problem you will have to remove the carb, soak it in carb cleaner for a couple of hours and possibly rebuild it.

VT1100 has two spark plugs per cylinder, the sparkplug caps are snap-ons so they're fairly easy to remove. You need a spark plug socket wrench to remove and replace the spark plugs.
