1992 yamaha big bear 350 carburator issues


Recommended Posts

  • I WANTED TO UPGRADE THE CARBURATOR ON MY 1992 BIG BEAR 350, SO I ORDERED A NEW CARB FROM EBAY.  ACCORDING TO THE WRITE-UP IT WAS A GOOD FIT FOR BIG BEARS FROM 1988 TO 1996.  WHEN I REMOVED MY ORIGINAL CARB I NOTICED THAT IT WAS DIFFERENT FROM THE NEW CARB MY CARB HAD TWO THROTTLE  CABLES THE NEW CARB ONLY HAD ONE CABLE.  HOW CAN I MAKE THIS CARB WORK ON MY TWO CABLE THROTTLE?

If the cam thingy the cables attach to has a reasonably strong spring you could run it with only one cable. In the two cable setups they have a cable to return the throttle to idle. It's a safety feature, usually on competition bikes that get used at full throttle a lot. Some though have a slightly weaker return spring than the normal one cable carbs and you need to be sure your cable is in good condition and routed correctly, and that your kill switch works..haha.

There is a good chance though that  that carby isn't really going to be suitable for your bike. I'd consider returning it and trying for the right carby for your bike. That been said though, almost every after-market carb is tuned in a generic sort of way that doesn't suit any particular bike or market and they always seem to take a bit of retuning.. So.. why don't you just repair your old carburetor.. Most of the time they just need a complete strip down and thorough clean out.

      I just brought home a used 2005 Yamaha Big Bear 400 4x4. It needs front wheel bearings, and a new choke cable. I think i can handle those two items. However, when i went to look at it, it ran good, shifted good, brakes all workds great, but at home when i started it, it would idle nice, but when i gave it gas it seemed like it was flooding out and would die. If i just gave it a little throttle it built up RPMs but any more throttle it began dying out again.
      any suggestions why it's doing that? 
      I'm looking for a service manual, but forum rules say i have to make 10 posts..lol

      Well, I bought the Axis 500 sold at Lowes for $8999 a couple days ago.  This post will be about my impressions as I use, fix, and abuse the machine.  I will add to the post as I gain experience with it.
      Thanks to other posters on this site warning of new machines with loose hardware, one of my first actions was to crawl all over it checking fluids and connections.  Zirks were all freshly greased, fluids in engine, and gear boxes were up to level.  One of the little gas struts that help lift the bed to dump was dangling with only one end connected, and the other strut had not been fully tightened.
      Here are some things I don't like:
      The rear gearbox does not have a differential in it.  It is essentially a solid axle.  Tight turns on lawn will leave tracks, and turns are not as tight on pavement.  In my case this won't matter much, but if you plan to use it on a lawn, this will create tracks on turns.
      To check engine oil you need to remove both front seats and a plastic cover.  This according to the manual.  I'm pretty sure it can be checked with that stuff in place, either from under or above, but that remains to be seen.
      I am not used to a CVT transmission.  I am used to a clutch and multiple gears.  This one requires giving it plenty of gas out of the hole and then backing off to get it to shift up.  I'm sure I will get used to it, but I'd like to be able to take off quietly if I want to.
      The doors have bungie cords to act as springs to close them.  I removed the driver door so I would not need to fight the constant pressure to close.  Problem solved.  I will leave the passenger door as is.  Gotta keep the grandkids safe.
      The status display is hard to read if the sun is on it.
       
      Here is some stuff I like: 
      I was concerned about there being enough torque to slowly climb a steep hill.  There is.  I will elaborate more on this when I've had it on my steeper trails.
      The display has dedicated lights to indicate status of gear position, low oil pressure, over temp, and a bunch of other stuff.  This helps a beginner with feedback that an action taken was successful.
      The sparsity of knobs on the tires dig in well on most surfaces.  I bet they wear out fast on pavement.
      The tilt bed has a tail gate that is easy to operate.  Much like early Japan pickups.
      Steering is responsive and little slack.  Remains to be seen how long to get loose since the u-joints are operating at quite sharp angles.
      Seats are pretty nice.  Will be interesting to see how long it will take me to poke a screw driver though them.
      Seat belts are included to hold grand kids in.  Won't go over 5 mph if both aren't buckled.  Yeah, it works to buckle them empty.  Doing this leaves the belt high on back, so you don't have to sit on it. 
      Hauling it home, my trailer wheel wells were too close together to clear the tires of the UTV.  This required driving it off center a bit, with one set of tires inside the wells and one side driving over the wheel well.  Creeping over the one well required climbing a 10 inch vertical well.  The ability to lock the front axle differential kept both front wheels pulling as I drove the one side up and over the wheel well.  The guys at Lowes were impressed.  They won't touch any but an unobstructed flat trailer loading.
       
      As I gain more experience I will add to this topic,

      Finally getting around to the Yamaha Big Bear that followed me home in August. It is a mess. I got it off of marketplace, the add stated " runs like nothing is wrong the only thing that's wrong is it needs a new wiring harness". So iv been looking for a new wiring harness although it came with a wiring harness that was out of the bike, so I assumed he had ripped it out. All the plastics were off and no screws or bolts to reinstall but they were in good shape. The coil, voltage regulator and starter solenoid was missing but came with new one. So I go out expecting to start installing the wiring harness and find out its still in tact with these parts missing. The first thing I found was the engine was stuck and there was no spark plug in it. I noticed when I bought it that the pull starter wouldn't rotate the engine but he assured me the engine wasn't stuck that there was something wrong with the pull starter, I was skeptical but took him at his word. I didn't check it that closely because I was really just buying it for the tires and wheels they were worth twice what I paid for the bike. Im a little new at buying on marketplace and am just angry that someone would lie like that, now I don't know if anything is really wrong with the wiring harness, im probably too trusting I usually trust people until they give me a reason not too. I would have bought it anyway, if I go to the trouble of hooking up my trailer and wench and driving there its coming home with me, long as its a Honda or Yamaha I can fix it. It took PB Blaster about 24 hr and I got the engine freed up, and it has good compression, using ye ole thumb over the hole test, and the pull starter works fine Thats enough of that, now for my real question, before I go to the trouble of chasing the wiring problem down I would like to see if the engine is ok , is there anyway to feed voltage directly into the cdi to make it spark.

      Howdy from Oregon!
      I'm wanting a SxS for operating on my own property.  I would use it to haul chainsaw, cables, axe, machete and other stuff to maintain several miles of foot paths.  Also I would use it to make the daily 1 mile round trip to the mail box.  I expect I would use it a hundred hours per year. 
      I am grossed out by the price of new machines, and after reading the service manual of a Polaris RZR 400, I am not happy with the maintenance required either.  It seems a used machine has quite a number of areas that would be potential problems if a used machine wasn't kept up properly with maintenance.
      4x4 quads seem a lot cheaper, and simpler to maintain, but have the drawbacks of no "bed" and maybe? side-hill stability. 
      Your thoughts, please?
