yammy is acting up

ok so i have a yamaha fzr600 and it was left to sit since last fall at my moms because i lost my license. its 2 hrs away and i wasnt able to get up there to run it so it sat... ok so yesterday i go to try and start it up. she starts off after i twist the throttle while starting but will only run with the choke open. whenever i close the choke it cuts. so i leave the choke open a little just to get a feel so i can ride it around the block. for some reason the bike tends to lurch and jump when accelerating and just tooling around. i assume its from bad gas or sitting or carbs. i threw some sta-bil in the gas tank because it has some fuel line cleaner and carb cleaner to see if that helped. any ideas?

right now, you want to first, take the fuel in the tank out, put FRESH gas in, along with some seafoam, and let it do its thing. if that fails, you need to take the carbs apart and clean them out individually.

That sounds about right. And putting in sta-bil now does NO GOOD.

Have you checked your spark plugs?

And lets be sure we are using similar language...

Open choke = you put on the choke????

Do you understand the choke? It "chokes" the air to enrichen the gas to air mixture.

So you're not running the choke then....

There is no problem with that... but again... what are your plugs telling you?
