Question about 2006 Yamaha V Star 1100 Custom

Yamaha V-Star 1100 backfires and will not run without choke on

I did not winterize my V-Star 1100. Now the bike continually backfires and will only run with the choke fully on. I've put in fresh gas and added carburetor cleaner. When the choke is move a quarter way off the bike shuts down. I want to get it to run so I can ride it to the shop for expert repair.

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! :)

You should do a carb clean. The carb should be removed from the bike and completely disassembled and dipped in carb cleaner. What I think works best for cleaning carb is Yamaha's Carb Dip I mix it 50/50 with warm water. All the rubber parts must be removed as they will be swell and be damaged by the dip. After you dip the carb it will need the all passages verified with spray carb clean to make sure the fluid will make it through the intended passage. Or run it on the ckoke to the repair shop

Starts but takes a very long time to warm up. continually stalls when throttle applied. have to keep feathering throttle to keep running . spits ,sputters , backfires until fully warmed up


ColdI engines require a richer mixture to operate smoothly...so they have an enricher (aka choke).
If you are finding you need to keep the choke on longer.....you may have a lean mixture than normal.nother
Start by inspecting the carb and intake manifolds for any leaks (loose fittings....cracked hoses) that could be drawing in air, leaning the mixture.

Another common issue with bikes that have sat over winter...is plugged idle jets.....the fuel varnishes the tiny orifices in the carb. You could try a product like Seafoam in the fuel tank....run it abit to get the treated fuel in the carbs then let it sit overnight...allowing time for the chemical to work. Since the bike runs fine warm...this may clear things up for you.

At times my Yamaha V-star will not start when hot


Hello my name is Jonathan. I have worked on motorcycles including this model for 9 years.What is wrong with your bike could be a bunch problems from which it could a faulty ignition coil or even a faulty sensor that could cause the engine to run rich which I know it is running rich because of the complaint of black smoke. The only way I would know is to see the bike. If you need any assistance or even just for me to help steer you in the right direction. Please give me a call 479-280-4997

Last time I STARTED MY VSTAR 1100 I CHOKED IT FOR 10 SECONDS ON HIGH THEN MOVED TO MEDIUM CHOKE FOR 4 THEN TOOK OFF AT NO CHOKE. 2 WEEKS LATER. I started up bike Choke on high bike barely wanted to idle...


Sounds like your flooding it out with the choke out. Try the next time you go to start the bike when it's cold with the choke out and when it starts push the choke all the way in and keep it running with the throtle. If it runs better after doing this then your flooding it on start up. Use 1/2 choke to start cold and see what it does. Good Luck

Engine backfire


try pulling the choke out a little and see if that doesn't help.  If it does that is a sign that you are running too lean and need the jets in the carb increased or just the air mixture screw adjusted.  If the coke test doesn't help, please tell me more about how and when it acts up. Like after the motor is warmed up does the backfiring quit?
