Kodiak 400 cold weather problem

Recommended Posts

I have a 2001 Yamaha Kodiak 400 (YFM400FWAN©) On a recent hunting trip a problem popped up and I hope someone else has experienced this, so that I can learn from them instead of going on my own hunt for an answer.

The Problem:

On cold days (sub 25 degree) I choke the Kodiak and it starts instantly. It revs up and runs on "high idle" without any problem. However when I return the choke lever to its "normal" position the ATV continues to run and a very high idle. I cant put it into gear until the idle comes down, which it doesn't. In order to use the bike I have to shut it off and when I restart it I must place it into gear before the engine gets a chance to rev up. It then returns to a normal idle and the machine behaves normally. This only happens on real cold days but it is a problem I want to fix. Can anyone offer some help?

      Just got a 2001 300 2x4 Bayou that needs a shifter shaft. Is this a very hard replacement to do? What do I need to watch for? Is there a video on this repair?

      Hey guys, Thanks for looking at my post. I haven't had a lot of experience with problems like this before, so I'm a little bit at a loss. The Quad was really hard to shift, (the dirty carb leaking gas making it idle high didn't help either). The only Idea I have would be is that the torsion spring is worn out, and that there is a normal parameter for how much it should move when those two arms of the shift shaft assembly spread apart.  That's my thought. Maybe someone who has more knowledge then me can let me know if i'm on the right track 😀

      I bought a used 2017 Outty 1000r and have been hearing about folks melting plastics due to excessive heat near the pipe.
      It's winter here & I've been plowing my drive for a couple months without heat issues. I'd like any input if this will be a problem come summer?!?
      TIA

      I have a 1998 yamaha grizzly 600 4x4 I have put back to life but as soon as I had all the bugs out it blew the special "L" plug out. What causes this? Is there something special I have to do to replace this?

      my o4 polaris 4x4 lost power just going down road at 10 miles an hour . Had only been on it for 20 minutes. Engine still ran just no power. Shifted into reverse had little power. Shifted back in forward and it ran for about 5 minutes then no power again. Was afraid to drive it any further so towed it back to cabin while still running..  It had power once again for a few mintues. No smell of anything burning . Several years ago I had to replace belt becasue it did something similiar. Could it be the belt again?

      Hi ya'll. I just got a 04 Kodiak 400 and Im confused.The left rear wheel moves like the bearing is shot so I figured its a quick fix. Much to my dismay when I looked at it before I tore into it ,it appears to have a drum brake-no bearing on the wheel. As this is the first time Id be working on a 4 wheeler job Im a bit hesitant. The manual only shows this has disk brakes.Its a sealed drum right behind the wheel.I pulled the wheel of expecting to find a bearing.Nope! Ive never done it before but it appears Ill have to pull the axle out to replace the bearing. Am I correct and if I am can anyone give me some advice on how to do it.The repair manual isn't much help. Thanks alot!
