SOURCE: 2005 650 V star won't idle
i would say its either drawing air or the carbs need setup. You have to check the breather pipes and the rubber manifolds for cracks or splits.
if carbs need setup, then its best taking it to a good garage, to have them balanced and adjusted.

If the bike runs better with the choke on a quarter or more of it's range when you're riding it can mean that your motorcycle's engine isn't getting enough fuel into the engine to run normally. Meaning you are running too little fuel into the engine. This can show up as a dead white spark plug with glassy bubble deposits around the electrode.
Possible reasons for this condition;
a. The fuel filter.
b. Most likely the motorcycle hasn't been run enough, this allows the fuel to evaporate in the carburetor and plug the jets that regulate the fuel/air mixture.
SOURCE: How difficult is it to install a new speedometer
That is a fairly easy task.
Remove the speedo bezel, and disconnect the wires and the speedo cable.
Remove the rear seat, then remove the front seat.
Unbolt the gas tank, turn fuel off, disconnect fuel line, slide tank back then remove.
Unscrew speedo cable from speedo drive at front wheel axle.
Note routing of speedo cable, remove speedo cable, install new cable using same routing as old cable. You will probably have to spin the inner cable to get it to properly engage the drive mechanism at the bottom. If you install the bottom first, you can turn the cable at the top with your fingers until the bottom fully seats.
Give each fitting for the speedo cable a slight twist (1/8 of a turn past finger tight) with a pair of pliers so they don't come loose
Reinstall all remaining parts in reverse order of dis-assembly.

Sounds like your carb jets may be partially plugged, common if they are stored incorrectly, The choke circuits on these carburetors work on manifold vacuum and if you throttle the bike while trying to start it you will lose the choke affect. if they are partially plugged the only good way to fix it is to pull the carburetors and clean them. I would advise checking out www.roadstarclinic.com is a great source of information for the yamaha star line of motorcycles.

I have the same bike and same problem. Check the intake hose that connects the carb to the motor it may have a crack mine did and lost power when the bike warmed up. They don't make a replacement hose for it so I am using a rubber plumbers coupling with hose clamps. Might work? The hose is inch and a half diameter and about three inches long try that maybe. Good luck If it makes a chirping sound when the bike gets warm it's probably that hose sucking in air and screwingup your mixture.
