Question about 2004 Yamaha V Star Classic

1 Answer

Yamaha V Star Classic not running properly.

I recently drove on the highway with my choke open for about 20 minutes. The next day, my bike wouldn't run over 50mph going in a direction, and rarely hit 20mph going uphill. I've already replaced both spark plugs multiple times, so I know that's not the problem. Also, i'm pretty sure that cleaning the carburetors won't solve anything. I don't have time to go to my local repair shop either.

Not getting any power unless choke is on


Only running good with the choke on is an indicator that the bike is normally running too lean. The fact that it runs good with the choke on at least tells me it is getting fuel to the carb(s). Therefore it seems probable that there is clogging in the carburetor jets or there is a big air leak between the engine and carb(s).

VSTAR 100, Stars with chick on full, dies when pushing choke to of and can not thorttle up with choke on.


You need to let the bike idle on choke for about 5-10 minutes before taking the choke off to ride it.

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.

Motorcycle runs with choke only?


You can try a good fuel additive such as "Seafoam" . Put it in the tank. The more the better to "clean out the carbs". Start her up and let it do it's thing. Let it just idle for a while and try to open the choke. If this does not do the trick. Then you will need to remove the carbs and take them apart and clean them-sorry. When you think you are going to let her set up for 2-3 months, run some Sty-byl fuel additive in your gas.

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
