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

Recommended Posts

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

had it, in a folder ...

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.

      We have a 2wd Bear Tracker that was flooded out by a tornado and I've since been trying to get it right. I've cleared the water out of the tank and now has fresh fuel, and I've opened the carb so many times I could do it blind folded under 10min. She'll fire up as soon as you turn the key and hit the button, even on a cold start, and idles perfectly. But the second you hit the gas it bogs down and dies. I had it running GREAT for about 10-15min once and suddenly ran like shit and limped it back to the house. I've barely got it to move under its own power since. I'm at a loss at this point. Does ANYONE know of something stupid I could've missed? The carb does have a fresh rebuilt kit that I put on about a month before the flood. It was not started until it dried, I cleared the tank and opened the carb the first time. I guess I'm just gonna pull the entire thing apart again and go from there. Maybe another rebuild kit? I'm gonna swear this thing is clean though. 
      Thanks for any ideas

      So we have a 2000 BearTracker 250cc. We got hit by a tornado and it got flooded out. Water was well over the handle bars and it actually moved almost 40 yards by the water. Anyway, I've pulled the carb and drained the tank. New fuel and a "clean" carb. It fires right up first crank like it used to but bogs down after you try and give it any gas. Think it could still be a carb issue? Carb had a fresh rebuild in April and might have 10-12 hours on it since. After we got it out, It was never started until I took the carb off and cleaned it along with draining the tank. Carb has now been off twice with no differences. Any other ideas?
      also the water seems to never end in the exhaust. I've gotten out as much as I could but it's still steaming quite a bit like there's more in there. Could this be the problem? I've never had an ATV get flooded out like this one before. Any help or other ideas would be great. Thanks yal.

      Bought a 01 bear tracker and a trailer from a local guy last week. I rebuilt the carb 2 days ago and ran damn near perfect for 2 hours. Parked it and came back the next day. It suddenly won't hold an idle at all and pops when I'm going downhill or at a slow speed. Almost like I'm dragging the whole power train with the weight of the ATV. It still has decent power (80-90% maybe as it is now) but I can't figure out why it's popping and won't hold an idle suddenly. even with messing with the idle screw next to the bowl on the exterior of the carb. No changes. . ANY ideas would be great. I'm far from a carb king, but I've never had this issue before. The fuel was bought 2 days ago and it has a brand new intake manifold as of yesterday when I rebuilt the carb (whole rebuild kit). I sprayed around the carb and did not find any leaks. 
       
       Thanks y'all.
