Hi, Jimh6232 if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will not idle unless the choke is full on and run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition and in the future pour in a bottle of fuel stabilizer and injector cleaner for you FI folks at least 2 times a year and before storage.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or more, any readings in the 11 volt range you need to do a proper "LOAD" test on the battery and replace as necessary, you may have 12.5 volts or better but little or zero amps, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a "CARB DIP" or if you have EFI remove injectors and clean with carb spray and compressed air
7. Check intake manifold and seals for leaks and cracks.
8. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
9. Replace spark plugs with new ones and check for spark.

SOURCE: engine idles fine, stalls soon as its given gas

Hi there!

Open up the carb and clean the jets with pressurized air. I also suspect water on the carburetor reservoir, before opening the carb, drain it first then run. Also, make sure the plugs are clean. Pull on the choke when twisting the accelerator, if it accelerates well, then warm the beast at normal temperature first before twisting the throttle hard again.

hope this helps-

SOURCE: 2005 1100 vstar wont start. srarter working fine.

If the bike ran well the day before, and nothing strange like no oil in the crankcase is going on, then the bike is likely to be fine. What isn't fine is the starter. The starter motor may be running fine but if the starter gear does not engage then the pistons are not going to move. It is time to call the dealer and talk with them as to repair or replacement cost. If replaced, keep the old starter for parts.

You may also want to check out a starter from a wrecked bike. Google " motorcycle salvage yamaha ". Chances are you can get a good starter for cheap.

Please rate this solution. Thanks! :)

You will most likely find that your Air Cleaner element is blocked & possibly may have sucked up some leaves reducing air flow.

SOURCE: my vstar 1100 dies when in idle. acceleration is

Is the idle speed set too low? If so, adjust it, using the idle speed adjusting screw, to the correct idle speed (900 RPM). If that's not the problem, then check for air leaks between the carburetors and the engine by spraying WD-40 around the intake manifolds with the engine running. If there is an intake leak, the engine RPM will change briefly when the WD-40 is sprayed near it.
Aside from that, there are two other things that can cause your engine to die when it should be idling: the idle speed mixture adjustment, or low cylinder compression. Of course, if it was idling fine before, and the idle mixture adjustment hasn't been changed, then do a compression check, first. To idle properly, each cylinder's compression needs to be at least 140 psi.

Without being there to listen to it, I would guess that you probably do have a carburettor issue. One of the carbs is not functioning properly causing a serious lack of power. The backfire at deceleration is most likely caused by leaks in the exhaust system, but could also be caused by an over fueling carb. I would remove and clean the carbs, pay close attention to the pilot jets and their circuits, (the pilots plug easily due to their small size), make sure the float needle and seat are clean and there is no noticeable groove around the tip of the float needle. Do not change any of the linkage or their related adjustment screws or you will need to re-balance,(synchronize), the carbs. Re-assemble and test. The oxygenated fuels that we are using these days will go bad in a short period of time, (weeks or months), even with a good fuel stabilizer. The most common fuel related issues that we have seen in the last couple of years has been plugged pilot jets and float needles with corrosion built up on the sides of the needle that cause them to stick in needle seat. We recommend using one of the fuel additive products that are on the market now that help to keep the insoluble particles suspended in the fuel so they can't congeal in the carbs.

Backfires on acceleration


Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

My 1100 V-star Classic idles fine. Once i ride it and it warms up it floods. You can hear the fuel pump pumping trying to keep up. It will only start with the choke on at that point.


Hi, Brtush04 and the usual suspects are:
1. Dirt or other foreign matter between float valve and its seat.
2. Float valve sticking.
3. Float valve and/or valve seat worn or damaged.
4. Float misadjusted.
5. Float cracked, leaky or damaged.
6. Excessive "PUMPING" of hand throttle grip.

Yamaha vstar 1100 back fireing


Re-jetting the carbs may be needed.
Imbalance of air/gas ratio will cause backfiring among many other things. :)

Other considerations:
Have the timing and valves set.

After market pipes will also increase the Poping sound when you let off the throttle. (not really backfiring but annoying)
Removing and plugging the AIS system will stop most of this.

Good luck!
Hope this helps.

Vstar 1100 idling rough and backfiring letting off the throttle


It sounds to me that your carbs might be a little gunked up - you mentioned the gas may have been old, so it's possible that the smaller (idle) jets are slightly plugged up. Fresh fuel might do the trick and/or you could try using a fuel system cleaner and water remover. This problem might 'solve itself' with a little time.

As far as the backfire - this might be either from the carb issue or it could be related to that rattle you mentioned - you could have a loose connection at or near the head - this can **** air and cause a backfire.

I hope this helped!

Fuel injected right? Sounds like you have some fuel injector issues now that the gas has varnished them up. Use stabilizer in the fuel anytime the bike will sit that long without being ridden.
