There is a resister in the spark plug caps that can cause a problem, try swapping the caps left to right and see if the miss changes side, the caps unscrew off the leads, if there is enough lenght cut 10mm off the end of the leads, when you screw the caps back on

HELP !!! I have a Yamaha VStar 650 that will Idle but as soon as I give it a little gas it dies.


Probably you did not need to replace those, are both cylinders running?
was the motorcycle sitting for any length of time?
make sure the carb low speed jets are clear use carb cleaner the can with the with the tube and make sure the low speed jet will flow the fuid through it. if its clogged take a strand of copper wire and clear them.

650 yamaha vstar 2006 stalls out when giving it gas


Hi, Donjkiii and the usual suspects are:
1. Idle port, transfer ports, slow air jet clogged.
2. Idle adjusting screw set too low.
3. Air fuel mixture adjustment too lean.
4. Pilot/slow fuel jet clogged.
5. Faulty accelerator pump.
6. Float level too low.
7. Float bowl contaminated old fuel, water, dirt, rust, etc.
8. Carburetor bowl vent line clogged/blocked/pinched.
9. Fuel line to carburetor kinked or pinched.
10. Fuel filter clogged.
11. Intake manifold leak.
12. The gas cap is not venting properly or fuel tank venting system blocked.
13. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
14. Needle and seat stuck closed in the float bowl.
15. Multi carburetors not in sync.
16. Faulty fuel pump.

My bike hasnt been ridden for a few months, and you need to give it full choke to start and keep it going, it wont idle when the choke is depressed, It is A Vstar 650 Classic


was fuel left in the carburetors when you parked it your metering jets might be slightly clogged with varnish i dont recomend opening them yourself take it to a professional and next time you park it for an extended period of time close the fuel valve and leave the bike running until the carbs run out of gas "the bike will stop running when this happens"

2001 v star 650 classic won't idle after being stored


You have a gummed up mainjet. Always store a gas engine with Staybul gas additive to avoid this problem in the future. Now, on to the current problem. Since the bike will at least idle your in luck. Just go down to an auto parts store and get a can of Sea Foam. I usually find it at NAPA it's a white can that looks like it came from a gas station in the 1940's Because it did. Mechanics have been useing it for years. Anyway, dump about half the can in the tank with a couple gallons of gas and fire it up. Let it idle a long time. Then start trying to ride it. You may have to let it set over night if it's really gummed up but it will clean it out. Easy fix, and you can leave it in with no problems. Happy motoring.

Hi Im Ed-I have a 2007 vstar 650 on the way back from work my bike started to loose power. If you give it a little throttle its ok 1/2 throttle or more it cuts out and sounds like a cylinder isn't firing...


konichi wa-one of the carbs is not producing or the electric not there-chec if float is sticking on bad side-is gas being delivered also-nothing seems to be combusting-inspect that plug n its cable for for contact-library has repair books-sayonara to arigato

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.
