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.

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

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: Need to get oil

First of all, I want to compliment you on your bike! That V-Star is in so many ways, one of the best all around bikes....Very durable engines, user friendly, comfortable and DEPENDABLE, not to mention one the best value to dollar ratio on the market, right along next to the Suzuki Boulevard....Not to get off subject but I enjoy these bikes thoroughly!

You want to make SURE that the only oil you use is a quality oil, which will have THE seal of approval stamp on the bottle that says that it meets the requirements of all the major motor corporations you want to make ABSOLUTELY sure that the ONLY oil that goes in that bike's crank case and gear box is specifically intended for use with a "MULTI-PLATE WET CLUTCH" system.....Otherwise a very bad day can be predicted. "Champion Oil" is a reputable brand and preferred thier 2-stroke raceing oil over all else when I raced 250cc class arena-cross. I have since retired from dirt bike racing to take up a much safer and peaceful profession in law enforcement....But I know Champion makes 4-stroke case oil thats compatible with wet clutches....Yama-Lube is ok too...Just make sure you see "Wet Clutch" on the bottle and it's all a matter of consistenly works best for you and preference after that.

1 Answer

I have a 05' Yamaha 650 V Star and it will only run if the choke is fully out, hot or cold engine. If the choke is pushed in, it immediately dies.


Has the bike been parked for two weeks or more? If so, the fuel has most likely gummed up and plugged fuel passages and jets. Might try adding 1/2 to full can of SeaFoam to existing fuel in the tank, crank the bike and run (with choke if you have to) at a high idle for several minutes. Shut it down and let set for an hour or so allowing the SeaFoam to work. Start bike again and run at high idle again, trying to run it without the choke. If this doesn't work, then the carb probablyneeds a tear down and a manuel cleaning and reset.

Will not stay running with choke out.


Gonna have to pull the carb(s) off and clean it(them)out. The low speed jets are stopped up, these are the small ones, the hole is just big enough to allow a single bristle from a wire brush to go thru. Do not make the hole any bigger this is asking for trouble, just clean it out so you can see light through it.

My 2006 yamaha v star 650 will run with choke on but will not rev . the engine will not run at all with the choke closed . if you cover the air intake it will rev


You have a vacumm hose loose look for small hose no connecter to anything - should solve it - I had a similar problem with a ZX9r the other day - same would run fine on choke not idle or start without it

Good Luck
