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.

SOURCE: how to lower the idle on a 2002 yamaha 650 v-star classic?

under the left side of the gas tank you will see i black knob/screw at the end of what looks like a hose. the knob faces the rear of bike. that adjusts the idle. its real easy to find and the only adjustment you can make to the carbs.

SOURCE: 2004 ford escape - feels like hesitation,or sputtering when acceleration, sometimes just random occurance, feel it sometimes while idling. Just had check engine lite come on, showed was o2 sensors, r

Try cleaning the Mass airflow sensor and replacing the air filter. You can buy the spray MAF sensor cleaner from any auto parts store for about $6.00, ask the parts guy how to use it.

My 02 yamaha vstar 650 is very hard to start on cold mornings. ihave tried all kinds of things. i have to idle it up than idle it down than it will start. the chock does no good .


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.
