atc 125m new member please help

Recommended Posts

hello everyone i have an 1984 atc 125m and it now longer produces spark and my manual tells you what to do just not how to, today i was messing around looking for the grounds i got one off and wire brushed it and the other i could not get off to inspect...

so i was hoping i could find out how many grounds the 125m has and possibly if a more experienced member can walk me thru how to get it running again,and has this happened to anyone else?

p.s. while inspecting the coil i unplugged it brushed it off and while hooking it back a spark gapped from the prong to the wire so its getting spark... kind of

I would definately get a manual for that machine. You can try and find one online or download a torrent if you've used that method before. I saw some downloads available: 1984 atc 125m torrent search+

Check the connection between the coil wire and plug boot. The plug boot should have a scew in the end that attatches to the coil wire. Unscrew the boot, make sure there is good, fresh wire at the end of the coil wire, clip it back a bit if you need to with a pair of diagonal cutters. When you have made sure you have good wire right at the end of the coil wire, firmly push the boot back on and gently screw it back on. You want it on well, but don't turn it too tight as that will damage the wires inside the coil wire. That is the one of the simplest scenarios and it wont cost you anything to check it so I would start with that. Beyond that, study that diagram that MWKE provided and start looking for damaged or loose connections, if you still are having problems, you will probably need to do tests on the ignition components. A good service manual will give you specs and directions on how to do these tests. I would definately check out the link that Ajmboy posted for you.

      I came across an odd temporary fix for a 1985 yamaha 80 ATV.  It has no spark, yet if I warm the CDI unit up a bit with a heat gun or hair dryer then it fires right up and runs fine until shut off then it returns to no spark until warmed up again. Partzilla shows $217 for a new CDI  
      It's sort of nuts how I found out the fix to warm it up. My old shop TV requires my heat gun warm up around the transformer area every day before it will turn on too.

      Hi there
      I am in need of a manual for my KLF 300 Bayou 4x2 . I've found others on here for the 4x4 model, but was wondering if I need a separate 4x2 manual. Does anyone know?

      What’s up people I am new to the forum and am glad to be here. I have been into bikes for oh I guess 40+ years or so. I haven’t had one in a while but my 27-year-old son has always wanted a Banshee and he finally got one and the guy he bought it from had two of them. I almost bought the second one but I did not want to spend the next month on the sofa. So he had a LT-Z 400 Suzuki and I picked it up for $800, I could not pass that deal up. We could have bought both Banshee for $7000 as he wanted $7900 for both of them. But He wanted $4200 and was not budging for the one my son bought and $1400 for the Z400 and we got both of them for $5000. He wanted $4200 for the Banshee so I got the Z400 for $800, a steal. Anyway it’s good to be here. Peace.

      I bought this old three wheeler that I found in a barn. It looked pretty rough, but I have it running now and functioning.
      With the switch set to "run" and the key in the "on" position the electric starter does not work when I push the starter button,
      However, if I cross the solenoid it will work and it will start the engine - so I know the starter motor is good and it works.
      Now, it gets a little mysterious. When the engine is running, AND the headlight is on high beam, the electric starter will engage when the starter button is pushed.....When its already running! (when the headlight is off or on "low" the starter button does nothing, only when running and in high beam will you hear the starter motor zing when you push the starter button) So, I know the button actually works, but only after the engine is already running and the high beam is on!
      So to recap: with the key on, the starter button does nothing. crossing the solenoid will make the starter work, and after the engine is running the starter will work with the button!
      Has anyone else had this problem? Can anyone point me in the right direction on solving this one?
