HI Nate!

A few things to check, 1. When you put the new flywheel on did you reinstall the woodruff key on the shaft its a little half moon shaped thing that goes on the cut out on the crank shaft its tricky to get on correctly?

2. If you removed the stator which is underneath the flywheel, and replaced the Phillips screws with allen heads, you may have to shave them down as I have seen a few heads too long and it get hung up.

3. make sure that all the coils on the stator are tight if a screw backed out it will allow a coil to move and it doesn't take much to hit the magnets.

4. Lastly with the flywheel off , give it a couple easy kicks and see if its binding with out the flywheel if so could be a bad rod bearing, or a ring snagging a port and not the flywheel at all or a few other things over in the tranny area.

Report back what ya find if anything, making a short vid or a couple pics can sometimes help to solve an issue!

Thanks, I got it working now i figured out that the screw holding stator on was sticking out to much and interfering. Just curious do you know size of the idle screw, because my carb seem to be missing it?

Thanks

The idle screw is located on the big silver box on top of the carb called the (TORS assembly), you can get to it by removing the seat. If that isnt the one you are referring to see the diagram in this link you should be able to order just about any piece there! Just click the drop down box and click on carb :wink:

      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

      My uncle bought a Baja 250, 2006. Knew there was no spark since the get go. He don't know anything about quads so is getting me to help him try to get it running...
       
      battery is bad so I connected battery charger to it to crank it over , cranks over well , but no spark .... 
      Lights and everything work fine , but with each crank over using the e start switch , the display reads 999 888 777 666 ... Right down to 000 and repeats itself . 
       
      He managed to get a parts bike , I changed over the CDI and the coil and the stator from the parts bike and there was another black box by the voltage regulator I changed over ... I used my multimeter to confirm as much as I could works , it's hard without knowing which wires are which , and I cannot find any diagrams online for this bike ? 
       
      Do you think it could be the Killswitch? There's so many wires coming from there I don't know where to start . Also I should mention it appears the fan on the front of the bike has been taken off (the wires have been cut too ) 
       
      If this bike sparked it would run . The previous owner said he parked it one day and it just wouldn't start after.

      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?

      Hello I’m new here and was wondering is anyone knew of good replacement part numbers for front struts and rear shocks for this atv? I think I’ve found a new rear shock, that looks like the original but there is no dimensions or anything and was wondering if there are any afterMarket new front struts available. I know it’s a long shot but any help would be appreciated.

      1996 4x4 Timberwolf rearend width. Can someone with some knowledge of these machines answer this question for me please. Are all 4x4 timberwolves this narrow in the rearend? These tires are so close the right one actually rubs the muffler.  Thinking about seeing if there are any spacers out there for it. I need at least an inch more clearance.
