2000 Yamaha Bear Tracker 250cc Flooded help

Recommended Posts

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.

Did you also change the  oil and filter?.. Water  vapor  could be coming  from  water  in the oil  boiling  off and  entering  the  intake through the  breather tube for the  crankcase.  Try adjusting the  idle  air  screw and or  the  needle valve settings. Bogging  on  acceleration sounds like  it  isn't  getting enough  fuel  (running  lean) when  you open the  throttle.

      Hey guys, figure you guys would have some helpful direction or answers.
      So, 05 Sportsman 700 carb, new carb, fuel pump, new plugs, new air filter, new everything I can think of that is usually the running issues. Starts up fine, seems to run fine, but if under load, two people, or even one person, up a hill, or pulling a drag chain for the driveway, it starts to cut out and sputters and loses all power, until I back off on the throttle and just barely try to let itself catch itself and then I can take off again.
      I am going crazy trying to figure this thing out. Other than that, the quad runs great. Parents bought bran new, just used around the property, 5000 miles on it. Any ideas???

      Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00.  It's been sitting outside with no carburetor on it for about a year.  Its rusty, missing some parts, wiring is all cut up and spliced etc.  No seat, no racks but the plastic is all there minus the headlight housing.  Anyway, who can pass up a $40.00 quad right?  I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water.  I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine.  I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark.  Did a quick compression test, 70 lbs.  Wet test bumped it up to 90.  Ok, so rings and cylinder washed out with water for a year, not too surprised.  I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show  it's got life.  Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either.  The compression is now around 60.
        Anyway, my question is....is it worth it to try to get this thing going?  I tore the top end down today and the cam and one of the rockers is pretty worn.  I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well.  Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again.  Much less just to make it run and use as-is but I won't really like it until it's right.  I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
      I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much.  I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down?  I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
       
      I'll get some pictures today if anyone want to see them.
       
      thanks!

      Yamaha Australia has announced it will discontinue selling Utility ATVs due to new Australian government legislation that requires the mandatory fitment of so-called Operator Protective Devices (OPDs), YMA will not sell utility ATVs after the government compliance deadline of 11 October 2021.
      “The decision to make the fitment of OPDs compulsory is disappointing. The ruling has forced us to withdraw utility ATVs from the Australian market because as a manufacturer we are not willing to gamble with our customers lives by bolting untested devices onto our specifically engineered and designed ATVs,” explains YMA Director Brad Ryan.
      As the market leader in this segment, Yamaha recognises that utility ATVs are an important part of farm operations and will comply with stage one of the new consumer legislation. This includes testing and the fitment of warning labels by Oct 2020. This will ensure that Yamaha ATVs remain available until October 2021.
      After this date customers will not be able to purchase a new Yamaha utility ATV in Australia – but sport and youth models will continue to be available. This is because new sport and fun ATVs do not need to be fitted with OPDs. In addition, side-by-side vehicles (SSVs) are not affected by this ruling, so YMA will support our utility ATV dealers and ease the transition from ATV to AG bike and SSV business.
      “Fortunately, our utility ATV customers can transition to our equally capable lineup of AG bikes and expanding SSV range,” adds YMA Director Brad Ryan.
      Customer safety has always been our priority. YMA has provided market leading rider training and promoted proven safety methods. YMA also helped develop the Shark ATV helmet which is the only fully certified farm safe ATV helmet available. YMA feels so strongly about customer safety that purchasers of new Yamaha utility vehicles will receive a free Shark farm safe helmet valued at $250 while stocks last.
      YMA is also fully committed to customer care via a national dealer network that will continue to service ATVs and with the supply of parts and accessories into the future.

      Howdy y'all. Just bought myself a 2004? Yamaha 400 with electrical Gremlins aplenty. Runs good (after jumping the starter solenoid relay terminals with the helpfully included with the sale pliers) but no fan when my wife's 03 Kodiak 400 had fan and the starter button makes it to the starter solenoid but the ECU side isn't happy. This seems to be a lively forum with manual downloads being supported so hi.
      Oh yah, and you can get two Kodiak 400s on a 5x8 trailer... I bought a nice 14' trailer as soon as possible after this.
