Hi from Sugar Land TX

[stevear1961]

Hello my name is Steve and I live in TX.
I have a fairly new GZ-250, it only has 153 miles on it, I bought it new for my Son in 2009 but he has hardly ridden it at all, the only miles on it are mine and I have not used it in almost a year, I don't know anything about motor cycles really but need to learn. My problem is that after it sitting in the garage for so long the bike will not allow me to throttle back at all without stalling, I have to keep the choke fully open, the bike will idle OK but if I cut the choke back at all it quits, I'm thinking the fuel system needs checking out. Can anyone point me in the right direction.
Thanks
Steve

Welcome to the board.

Clean the fuel system with Berryman's B-12 or Seafoam (just put it in the tank). You might have to pull the jet and clean it out if its really that bad. Music Man has a method that he hasn't posted, that is unorthodox but works very well too. I'll let him chime in on that if he's willing.

Check out my video on my Ninja 250, does it do this?

Welcome, and I agree with the Berrymans approach.

Welcome, and I agree with the Berrymans approach.

:plus1: When you put your cleaner in the tank make sure you go for a good ride and you should see a difference.Sometimes it takes a couple of tanks fulls to see full improvement.When you are going to not run the bike for awhile you can avoid this problem by putting STABIL in the fuel.By the way,welcome!

Thanks for all the prompt replies, I will stop on the way home to get some Berryman's B12
Cheers

That's a good idea but sometimes the clogging is so bad it's impossible to ride. A good pull-apart and soak is probably best, or if you're not handy with intricate carb parts, MM's approach might just work out for you.

Follow the instructions on the bottle. A more is better approach can sometimes backfire. Don't ask me how I know. :whistle:

Great video/audio Patrick, that is very good information to be aware of. Thanks for posting it.

I use Sea-foam in mine, and Sta-bil during off winter season. I also use sea-foam a few times during the year to keep things cleaned out. We rode at least 1 full ride every month since we had the bike (Jan 1, 2011 for the month of January). I like to do at least a 30-60 mile ride each time. So far no problems with ours. After sitting for 2-3 weeks straight in the cold, it does take a little time for it to start. I try to go easy and let everything warm up good before going fast with it. GZBrian

That video just answered one of my questions. I had a 1984 Honda Magna 700 and it sounded just like that except beefier. I got so frustrated because the throttle was sooo unresponsive, just like that ninja in the video, was doing the exact same thing....idle was a PITA to get stabilized. Also would not take off uphill. I had let it sit all winter unwinterized though. It wouldn't start at all and the seafoam finally got it started, ran really well after taht but was still unresponsive on the throttle and quirky. The guy I sold it to said he took it to the shop and they said it was the nicest older Magna they had ever seen, but the carbs were dirty, once the carbs were cleaned, would run like a charm.

I am actually thinking about buying a second gz250 this weekend but I was concerned about the carb. The lady said she just had it cleaned by a friend, so no paperwork, so I was wondering how to tell if it was really clean or not...thanks!

If the bike responds well,idles good,and pulls good,you should be good to go.
