I have to many to post I am finding problems left and right on it but i was curious if anyone knew what are some CDI symptoms are?

Also when I start it up it takes about 20 mins before i can even get it moving it stops moving when ever the fan comes on also got any ideas

It also makes a loud pop noise and and a flame comes out of the exhaust.

The previous owner put all the wires for almost everything together and taped it up so i am trying to test everything to c why its acting up.

400 artic cat year 2000 4x4

I cranked her up and the CDI started smoking then the engine died, got any ideas on how to trouble shoot it or possibly why it did that and how to fix it. What is the price range for buying a new one

Regulator/rectifier might be bad, sending too much voltage to the ignition.

I merged your two threads together, they are still basically the same subject, in the future, just go ahead and add to your first thread unless it is a completely different issue.

The problem may also just be your CDI by itself, obvoiusly that needs to be replaced, so I would start with that, if you keep having problems after replacing the CDI, then I would look to the other things, like the regulator/rectifier. Babbits online parts has some good prices on OEM parts.

Since you mentioned the previous owner did his own wiring there is a possibility something wasn't done right or something shorted. I would test first to make sure your regulator didn't crap out and cause an over voltage condition. That could be why the CDI fried.

In this forum, I posted a link for Arctic Cat service manuals. Now there isn't one for the 2000 model, the earliest year I see for the 400 is 2003. However, the 4th file down from the list is ALL the schematics for ALL Arctic Cat ATV's & Sleds from the year 2000-2009. It is a large file (about 438 megs) but it has the schematics you need.

Here is the link...

      Hi guys new to this forum and thought I’d jump on as I’ve just bought my first quad a Kawasaki bayou klf300c 89 model. It had starting issues when I bought it so I’ve gone thru and replaced the cdi, voltage regulator and starter solenoid aswell as rebuilt the starter motor after all this it was still free spinning on electric start so I pulled the stator cover off to find the fly wheel wasn’t spinning so replaced the one way clutch bearing put it all back together and still not engaging at all. I’m at a loss and looking for some ideas on we’re to look next to solve the problem
      cheers Ben 👍

      So I’ve had this quad for the better part of a month, and it’s been hard to start since the day I bought it. Once it warms up it idles just fine and has plenty of power and starts no problem, but cold it takes 20 seconds minimum of straight cranking to start it.
      It’s not really too big of an issue, I’m just curious as to why it takes so long. Earlier today, it took me about 2 minutes of on/off cranking to get it to fire.
      i have attached a video of a cold start to show you what I mean.

      Hello,
      I recently picked up an ‘07 KFX 700. All was going well, rode it about 40 miles, when it started bogging at low speeds. If I kept the revs higher, I was just fine. Also, a persistent issue since I picked it up is the fairly difficult start (but it is abnormally cold right now and the quad is jetted for the dunes at summertime).
      Regarding the complete lack of idle, I have to rev it a couple times to get it to idle after starting it, after which it’s 50/50 whether it remains idling. I don’t have low fuel, but all of this began after I rode it pretty hard and the radiator fan kicked in. Might be overheating, just wanted to hear your opinions.

      So I was looking at my John Deere today and though, how could I make this cooler. So I tinted the windows. Lol.
       
      As I got home I was staring at my Polaris and the wife’s kfx. I thought I would have to replace the crank because of piston slap on the Polaris. Turns out I just had to adjust the choke cable a tad more. Runs great.
       
      Why do we have insurance if we only need it sometimes, and that’s questionable.

      So when im ridding in high gear randomly sometimes it will go into a persay limp mode and only allows a max of 30kmph and it sounds like a rev limiter, what would cause this and how to eliminate this all togeter as in the new ones with the over ride switch. its the sound that it does in low range or reverse. i want this gone period when i get stuck in mud i cann spin tires fast enough. and while im in high gear i dont want this happening. if you need more details the easier way of getting a hold of me rather then the forum is my email [email protected] i dont have time to check back here oftern but i get my emails right away.. thanks guys

      I've already posted here once about this ATV. Lots of people suggested i check the cam and after a couple months i finally got around to attacking it. I got it all apart and got the cam/rockers out. I'm almost positive they need to be replaced, they're pretty scored up and don't look too hot. Just wanted some final opinions before i drop the money on it. I'll also take feedback on the new cam i've chosen.

      i have a 2000 suzuki king quad lt-f300f that i picked up as a project bike. it didnt run well when it was parked outside 5 years ago. it cranked after putting fresh gas - but would not run below half throttle, i took apart the carb, cleaned debris, and re-assembled. i suspect that the pilot needle is sheared off - it never protrudes into the throttle body through the pinhole. now to get the bike to ALMOST idle, the throttle idle adjustment knob is all the way up/in. the pilot needle is turned almost all the way in/up (if i understand correct, it should nominally be out 2 1/4 turns or so). and like i said, it will ALMOST idle. floods easily, rides rough.
      wanted to hear from those more experienced than me with suzukis - and im self-taught atv repair, so dont laugh too hard if my verbiage/part names is way off. 
      facing the driver's side of the bike [US] there are three hoses on this side of the carb. without a service manual or way of knowing what was messed up before i got it, i think i have them right: front hose as a vacuum to the petcock, middle hose as vacuum to the fuel pump, rear hose as fuel line from the fuel pump. running the bike in prime position results in flooding even while riding. with all hoses disconnected from the carb, fuel slowly drips from the vacuum line connected to the petcock.
      so just my speculation is that the diaphragm in the petcock is split, and the pilot needle is broke off - causing my inability to not quite idle and the rough ride. this suzuki is hoses and cables everywhere compared to the honda ranchers and yamaha warriors i am used to. I would like to have a plan rather than: replace everything at once.
      is my speculation on the right track, or could something else be at play? say, if the compression was non-existent, would that cause non-idling? i am all ears, look forward to the input.

      I traded my dirt bike for a 2000 arctic cat 500 semi automatic. when i went to go pick it up the guy said it didn't get spark, so i thought it was going to be something simple like a coil. well it wasn't. first thing i did was take all the plastics off to get easy asses to every thing. so i bought a brand new battery for it seeing if it got power, it didn't. the dash wouldn't light up neither would the lights, so then i tried to see if the starter worked it didn't so i jumped the solenoid and the starter started turning over the motor. so i bought a new starter solenoid, when i installed it the electric start still wouldn't work , so i bought a new kill switch and starter switch that goes on the handle bars, when i installed it, the electric start still wouldn't work. so then i went to see if i could get spark by pull starting it, i didn't get any spark, so i bought a new spark plug, and guess what, still no spark, so then i bought a new coil for it to see if that would fix it. so i installed the new coil and guess what no spark still and still no power to the dash. so to sum it up i'm not getting any power any where to the four wheeler. so i cleaned all the leads and plugs and still nothing. so then yesterday i took the wiring apart to see if their was any frayed wires, and no their wasn't. does any one have any ideas what this could be i'm up for anything. also if any one knows how to bypass all the wiring just to get it to start i open to that to, or if someone knows where  i can get a wiring diagram.

      i have recently purchased a yamaha kodiak ultramatic 400cc. it is used and sat outside for a long time. i have done a lot of work on it and got it to run sort of. when i try to start it, it will start and run for a little bit then it will die, the time it runs varies. it has a new cdi, spark plug, and stator. most of the time it wont even start it just cranks over. there was one time that it started up right away and ran perfectly but the next time i tryed it wouldnt start. before that one time every time it started and ran it had a popping sound. i cant figure out why it wont run. any help would be muchly appreciated! thanks!
