My guess is the very small passages or jets in the carb are clogged. This is common after storage if you use gasoline containing Ethanol.
As the engine does start, try mixing in a heavy dosage of a product called Sea Foam. Run the engine to draw the gas mixture into the carb and then shut off and leave sit. Sitting for a few days is best if possible. The Sea Foam will dissolve the gunk clogging the tiny passages and should allow everything to run smooth after that.
If this doesn't work, you may need to pull the carb and have a local small engine mechanic clean it using his ultrasound cleaner.
Whenever you use gasoline with Ethanol, always put in a gas stabilizer such as "Ethanol Shield" or "Sea Foam". Put it in the gas can before you fill it at the gas station so it mixes well. (Ethanol starts to separate from the gas in as little as 30 days.)

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

Hi, Linda 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 or 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, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
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: battery seam like it is not charging

Some automatic battery chargers will not charge a REALLY low battery. You really need a volt/ohmmeter to check charging rate.
Should be 13.5--14.4 volts while charging, 12.5 volts for fully charged battery.

SOURCE: battery will not take charge, but can jump start and it runs, but does not keep charge

Possible charging coil under the flywheel issue, or with the retifier, there is a tool called a negative shunt, this will quickly tell you if there is any charge to the battary from the engine

I haven't rode my 2008 honda cbr 1000 for 6 months and when I got it back from storage where I winterized my bike and took the battery off of the bike. the battery level was %20. it is 700 miles on it....


batteries do lose charge if connected and not running for a while. when in storage you should disconnect the battery. specially if the storage area isn't heated.


hope this helps.

Check the fuel filter for plugging (which is common when fuel is left in the machine over winter storage). You should run the carburetor dry after emptying the fuel tank for storage.Hope this helps!
