How did you test spark, ground it and see?  Don't burn it, you'll figure it out!

      So i have an old yamaha bear tracker that was given to me from an old farmer I know. I decided to refurbished it and fix all the quick fixes on it. I am pretty sure that it is either a 1999 or 2000 based upon the original wiring harness. Little did i know when I bought a new to me wiring harness from ebay that it was from a 2003 or 2004. My question to everyone is do I need to have all the stop switch assemblies hooked up? I think there are three on the 03/04 models and only one on the 1999 to 2000. Any help I can get for this would be great. I haven't run it yet due to the motor and crankcase is in two totes.

      Hi Guys, I'm a newbie but pretty handy with a DMM (controls technician). I have been fighting a junker quad i picked up as a project bike, was assured it would run if I replaced the battery and cleaned the carb. I replaced the battery, rebuilt the carb with a OEM kit. FIxed all my switches and foul played circuitry from the last guy.... So I could get it to start long enough to test the quad, it seems okay from a trans/engine point. However I couldn't get the carb adjusted to idle to save my life with the idle air screw or the thumb screw on the card for the slide. I took it to a friend who is much more familiar with yamaha and quads and he double checked my carb rebuild all was fine, he adjusted the float to make the fuel not overfill which i missed.
      He pulled the air intake, got it started and couldn't get it to idle with or without air filter. We started looking at the spark plug (new) and he tested it with a spark plug clamp meter, tested good, pulled it and grounded and it had spark but he felt it was weak. I order a working used oem coil to try the easy things first. When I ohm out the coil on the quad with my Fluke i'm seeing .4 ohms on primary (ground lug to male connector) and 18K ohms on secondary (inside boot to ground lug). Seems like this forum is full of bear trackers so I'm hoping someone has some ideas to help me figure where to go with this. His thought was he know I ave fuel and he knows I have air, spark would be next. I have spark but possibly weak. Thanks

      Hey y'all. I have a Yamaha ymf 250 BearTracker. I got this thing for free from people whose son tore it to hell. So it wasn't in great shape to begin with. i.e. no indicator lights (neutral light for instance), no ignition switch or key( wires were twisted together to make it run), get the picture yet? 
      So when it ran it ran rough and I got it running for a year or two, just something fun for the kids to ride on with me on gravels.
      Now just randomly, the start button stopped working so I had to jump the solenoid, then put a temp start switch in. Kill switch would still work. 
      However, the thing has no spark what-so-ever. I've check continuity through the start button and it shows the contact is working, ohmed out the stator, everything is in spec, the reg/rec tested fine as well. I've replaced the solenoid on the off chance it could've been bad and the cdi unit as well, along the the little solenoid relay unit. I'm still getting no spark. The spark plugs is new as well and the coils to the plug have been tested and are good. I've tested and trouble shooted everything I can on this quad and no luck. I watched countless YouTube "no spark" situation videos and it's not helped. Does anyone have any tips or tricks I could try? Would really appreciate some input on this. Thanks!

      Have an Bear Tracker 250. Dont have the manual or any literature to help with. Anyhow, starts with pull start in gear, and electric starter doesnt work. Also, neutral light doesnt come on. Where should I begin?? Need some direction on troubleshooting all this. Thanks a million.

      Trying to replace the carburetor on my 2003 Bear Tracker 250. Two brand new carbs in a row from different suppliers.   Both leak fuel out over flow and intake as soon as I turn the gas on. Any ideas. Am I doing something wrong?

      i am sure some one has switched from the dinky battery to a larger car car battery, so any advice? ive got enough bits and bobs on my atv that i feel i need to step up, i keep a float charger on it but i left it unplugged for about a week and it was dead and it a fairly new battery from advance auto, im probably gonna add a cb radio in the future and i think the only thin that has a constant draw is the clock in the dash and the memory for the stereo

      picked up my third timberwolf 250 for my daughters.  these are great light weight little quads.
       
      have a strange one for you.  the quad will NOT start in neutral.  it will start in first. 
      if i lift up on the gear selector just enough to hear the little click (its not loud, sounds like a contact clicking, perhaps the neutral safety switch?) the light will go out, but it won't yet be in first either.  that is how i have shown my daughter to start it and she can.
       
      id like to carry out whatever repair is needed.  i have the pdf of the shop manual but it doesn't really have a flow through diagram.
       
      any help appreciated!  thank you.
      i need to add something.  it feels like i can switch into another gear BELOW neutral.  
      so if i switch to neutral, i can keep pushing the gear selector, and it has another click below the neutral.  the light stays on, and when i pull up into first it kind of feels like it has two positions it moves through to arrive at first.

      I have a yamaha big bear 400, tested all fuses and relays. When I turn on key I get nothing, no neutral light or headlights. Could it be the key switch bad?

      I have a 1996 Kawasaki Mojave KSF250. I have no manual on it and it has a no spark issue. If anyone could give me a hand with this or would possibly have a manual would appreciate it.
