Help a noob! First ATV 2007 Yamaha Big Bear 250 2wd

[gixxerdk 10]

My ATV only starts when in full choke even after I let it warm up and ride around I try to lower the choke but will end up stalling. I just put seafoam in the gas tank and will try that out first in about 15 min. I'm just worried that when it gets cold I'll have issues. Also, when I try to lower the choke after being warmed up I hear no difference in the idle. Is there a way to adjust this?

Side question, when I do stall and im in gear its hard to go back into neutral to start it up again. I tried rocking back and forth but that didnt work. After 3 min it went into neutral smoothly.

First Welcome to Quad Crazy.

I would check and make sure you have the airbox lid on properly and there are no leaks from there to the carb. Then check the tank and make sure your fuel filter is not plugged or the bottom of the tank. Sometimes on plastic tanks some of the cut plastic can get in the lines and the jets.

The sea foam is great stuff but you really have to run a tank of gas or so before you start seeing the benifits.

Third I would hold off on adjusting the carb until you tried everything else, if it ran fine before then I would just clean the carb and not adjust it. Check the jets and see if they have anything in them.

For your other question, alot of quads have the start in gear feature, try holding the brake (Make sure the brake light comes on) and starting the quad.

Can the service manual listed earlier in this post be used for my model (Big Bear 2007)? Did the name change over the years but nothing has changed parts wise since 1998

[j1s1a1 10]

any luck finding LIT-11616-BT-26? I can not find it anywhere on the internet?

[oxidized_black 59]

no luck

Awesome, thanks. I just joined and found this and the owner's and service manual you posted. I just bought a used '07 Big Bear 250 and was looking for these docs. Do you have the service manual for the 2007 Big Bear 400 4x4? I have the owner manual since I bought it new but it would be great if I had the service manual too.

Thanks again, great info on here.
