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.

      Does anyone have a redcat 250 or falcon 250cc that they can share where the two vacuum lines on the carburetor that you run antifreeze through I honestly have no idea where the lines are suppose to go to circulate the antifreeze. 
       
      Any help is greatly appreciated.

      Recently I noticed gas leaking from under the gas tank on my 2005 250 2x4. As I looked closer it appears to be leaking from the shut off valve under the tank. It's the valve with the handle that can be turned to open, close or reserve. Can this part be replaced? Thank you.

      Just bought (Tue. evening) an '89 Suzuki 250 4wd that has been sitting out the last 5 yrs. It's complete, including the shift knobs, battery cover, and headlights. It has the optional cooling fan on it (probly stuck - didn't check), and the engine isn't locked up. Plastic looks good and isnt cracked. Racks aren't bent up. Shift lever works, the foot brake moves (needs oil - have to pull it up by hand), and there's black oil and no water in the engine sight glass. Guy was asking $125 and gladly took $100 for it. Anxious to get started on bringing it back to life. Been wanting one of these for years. As soon as I can get to it (working on a junky "Jackel" right now - Chinese Yamaha Timberwolf). I'm going to pull the tank off it and clean it, clean & possibly rebuild carb, put in new plug, and a battery, then see what happens. If nothing, will keep going until it runs. Feel free to respond if you want to, I'm mainly just excited and wanted to tell somebody.

      My quad runs,  it starts up runs for about 10 minutes and then it dies if you let it sit for 10 minutes it’ll start back up ride for another 10 minutes and then die again, trying to figure out why it keeps stalling

      The quad has done this off and on, almost since new, but it's gotten worse this year. Sometimes if I freshly charge the battery, it'll work fine, others times that won't matter. Turning the key to on it sounds like it's connecting as I go to the start position, slightly before the full turn, but it's not like there is just a sweet spot to find, it's totally erratic.
      Now the battery is basically dead so I put a new, slightly bigger AGM battery in today to replace the factory one with all of 800 miles on it, but those have lots of plowing hours included. 
      I was able to get it started once, but it still went into limp mode after just a few moments of driving it (that's another topic), so I put it back in the garage and started probing around. Now it doesn't even try to turn over.
      Is an ignition switch, the $18 shipped aftermarket variety on Amazon worth a shot? Or should I go straight for the starter? The new switch may not come for over a week, so I hate to just put my hopes in that if I'm missing something obvious. Fuses are good, so it's not something super obvious.

      So this’ll be long I’ll give all the background first to see my issue skip to the ***
      Hey I picked up a pit bike and a foreman for 800 the pit bike was running but the foreman was locked up.  Sold the pit bike but when I took the top end off the piston I only found half a piston left.  So knowing the rest of the piston was down in the crankcase I knew it had to be pulled and gone thru completely.
      to pull the motor I went ahead and pulled the rear end off and unbolted the front diff to pull the drive shafts and pull the motor.  Now I have the motor torn down completely and have all the parts of the piston removed.  I know the rod and crankshaft is shot (heat discoloration and too much up and down play rod to crankshaft).  
       
      ***so I’m wondering while I have the motor apart what should I check for?  I know this motor died from heat as the oil in the head smelled like popcorn.  So what should I check to make sure I fix the issue (overheating I assume) and not just the symptoms (blown up motor lol).
      so put simply I don’t want to just rebuild the motor to have it overheat and repeat the process after 5mins of running
      Here’s some pics
