Hi,
The first thing you need to check is the air filter. Sometimes critters can get into the airbox when a bike sits for awhile. Sounds crazy, but it has happened to me. If nothing is blocking the filter, give it a quick clean since you have it out.
Next things to check:
Faulty diaphragm
Improperly adjusted fuel level
Clogged or loose main jet
Faulty fuel pump
You may not be able to check these on your own, but these are the next likely culprits.
Hope this helped

1 maybe there is a diaghfram tear at your carb only 1 is funtioning and 1 block engine is running but under power
2.check your fuel line from tank to fuel filter then pump then carb
probally there is a debrie stuck in the pipe line or in your tank

Here are two solutions for you:
A - Take the carberator off and soak it in some good quality carb cleaner for about 1/2 an hour. That should take care of any residue in the carbs.
B - Alternatively (and for the less technical minded) there is a great product called Sea Foam. Try to find it at your local CSK auto/NAPA/Wal-Mart. Pour a small amount (maybe 1/4 ounce) into each cylinder chamber (take out the spark plugs), try to pour a small amount into the carbs (a turkey baster works great for this), and pour the rest into the gas tank. Let it sit for 5-10 minutes, then start it up. *NOTE - the bike will start VERY hard at first until it burns through what's in the cylinders. ALSO the fumes will be EXTREMELY strong and suffocating - make sure you do this OUTDOORS preferably, or at least in a VERY well ventilated area.
Good luck - I know how frustrating these things can be! :)
P.S. - I am a proud owner of a V-Star 1300 - great bikes! :)

Purchase a EFI controller. I suggest a Fi2000R. It is easy to hook up and fairly easy to set by the instructions.
