My big bear makes some crazy grinding/clanking noises when backing up. I am guessing that this is a fairly common problem since I am having a pretty hard time finding parts and when I do they are very expensive. Does anyone have any advice? What all is there out there for interchange?

My big bear also has some other issues....if I am running it all day, I will have to change the spark plug at least once because it will foul one out.

The rear end has been making this noise for over a year now and you can actually feel it through the machine also. My quad is not used for play but only work...search and rescue, running around the property pulling parts (80 acres), plowing snow, spraying weeds, fertilizing, and fencing. Once on a search and rescue mission while coming back on the gravel roads back to the trailers at top speed there was a loud bang like it bounded up and popped loose and continued going but it was loud and felt it very well. Has anyone else had these kinds of problems?

      TRX350D fuel pump problem
      By semicolon
      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      By HSTAR
      Hey I have a 1997 big bear 350 4x4
      I replaced the shifter shaft and the shift arm linkage and the rod when I installed them all I was unaware that you had to line the dot on the shifter shaft with the gap on the linkage arm gap put it all back  together and rode it I can't get it to shift in the right gears  I can move the shift cam by hand and goes in different gears but with the shifter shaft in it riding I can't put it in R or N 
      Anyone know how to line up the shifter shaft and the shift cam s

      1992 yamaha big bear 350 carburator issues
      By John Sinclair
      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?

      2012 John Deere Gator 850i RSX Idle Problem
      By N00bie
      From Arkansas. Just bought a 2012 Gator 850i RSX because I could not pass up the price. BUT it has an idle problem. So, to be honest, I joined just to get a service manual. I have a choice: 1)Buy a hard copy: ~$100; 2)Buy a CD ~$35.00; Get a direct download for free posting 10 times; or get a download for $29.00 (subscription). Haven't decided what to do yet.
