1997 Yamaha Kodiak 400 4x4 ATV

Recommended Posts

New to the forum, I have that year and model atv and I cannot get it to idle so far at all... I bought it off this lady who had let it set for two years without starting it.... I can get it to run as long as i use the throttle to start it, but when I let off it will not idle at all... I did buy a rebuild kit.. and the only things i changed was the things inside where the float goes... reckon one thing is called a needle valve... so changed that and anything else within the carburator where the float is at... including changing the float... I did notice the shut off for gas does not completely shut off when on the off spot... but still it should idle when starting it I would think.... I can pull the choke out all the way and it will idle but when i push the choke back in it will stall right away... can anyone help I do not know much about working on atvs..

also i cannot find a idle screw anywhere on the carburator, there is a real big screw around the bottom area facing toward the ground, but when i turn it i cannot tell a bit in the idleing rather i turn it one way are the other.. sure would appreicate any advice.. thank you

sounds like plugged up carb. needs a good cleaning and blast of compressed air. not sure if that carb has a fuel screw, just air i think, once in all the way, about 2 1/2 to 2 3/4 turns counter clockwise is about right .... and if you turn the carb upside down with the float bowl off, the float should be about half an inch or better from the housing to the bottom of float (or top when upside down).

thanks.. Mine also has the manual pull stick there is a cable going into the back of the carburator, maybe its not a choke cable, maybe its a throttle cable, I really do not know... I just no its bent at the end and goes then into the carburator, So I am trying to figure out how to remove it so i can take the carburator all the way off and either try to rebuilt it myself or have it rebuilt.

i removed the throttle cable on mine, but never the other cable. i can't remember why ... but i had enough room to pull it out of the frame and work on it ...

looking at the diagram i am thinking its the throttle cable that I need to remove to get the carburetor all the way off, I looked at the diagram and it shows two things as far as I can tell on the back side of the carb.. I call it the back side but really I guess if setting on the atv it would be considered the front side. it seems to have a long threated piece on it and then closer to the carb is a regular threated nut and there seens to be a small brace like piece that holds it in place attached with a phyllips screw... that is the piece anyways I need to remove so i can try to fix the carb.....

I have a couple of questions again please. In cleaning the carb i took the needle valve out.... it had a string on it and a rubber ring and a small washer... I need to know for sure how these go back because they fell out of the carb when i took the needle valve out and I am not unsure of how they go back in I think the spring first slides onto the needle valve, but what comes next if so the washer or the rubber O ring? Next I noticed the breather that i purchased does not set tightly into the hose that comes out of the carb would that keep it from idleing correctly? cause i can put something against the hose and it trys to idle? right now though i have the float off cause gas is pouring out of the carb when i try to start it... Thank you in advance

finally got the atv to run great... it was the intake hose that bolts to the intake then bolts to the carb... it had a big crack in it so was sucking air... now running great.

now i am trying to figure out how to ride it...lol.... maybe someone can tell me for sure I think I am doing it right but just need to be sure.... its a 5 speed manual.... it does not have a clutch on the handle bar that i seen in a video on youtube of how to ride a manual atv.... so all i can figure out is you just change it from one speed to the next by lifting up the clutch arm i guess you could call it with your left foot? is that correct, does anyone know about these type of atv's?

right on !!

yes, just shift with your foot when the revs sound right, like a car/truck. it's ok to kinda power shift going up in gears, but let the revs come down when you want to gear down, the transmission will work like a braking system too ...

      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.

      Just bought a LT 230 anything I should watch for. It runs and drive good. Just don't want no surprises

      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.

      ok help so according the service manual, Idle Air Mix Screw (aka Pilot screw) should be initially set to 2.5 turns out from fully seated.

      If I do that the motor doesn't want to start or stay running...right now the pilot screw is probably somewhere near 5 turns out....I'll take the carb off tomorrow to count to know for sure.

      mind you the carb got a new float seat,float needle and various other components in the kit.

      To get the motor running I hard to turn the pilot screw out quite a bit, and turned the idle speed screw in quite a bit...I didn't hook up an inductive tach to know what it is idling at, but does sound about right.

      What should the idle speed adjustment screw initially be set at (the one that has the black cable sheath with a knob you can twist easily)?

      Is there a special tool to turn the idle/pilot mix screw whilst the carb is on the running motor? I am using a slotted screw driver bit (normally goes into a driver) by hand..makes it hard to turn the driver and hard to tell how many turns .

      I just got a 1991 Yamaha Moto 4 for my son and I am looking for a service repair manual. I know that the timing chain needs replaced.
