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?

Having a strange issue with the headlights on my Kodiak. Noticed there are no high beams, and when I switch back to low beam the lights stay off. The low beams will come on, only if I go from off to low. This is what I have going on: From Off to Low - Lights Work From Low to High - No lights From High to Low - No Lights Back to Off and to low - Lights work again. Just curious if anyone has had a similar issue, or where I should start troubleshooting.

fighting this thing for a month now.No spark at plug. New ignition coil,pick up coil,stator,reg/rectifier,all new wiring.Started it up today rode for an hour shut it off.Tried to start later wont start.pulled plug wire it firing a blue spark while starter button is pressed.Tried new plug no change. It stared a couple times an ran for few seconds then died.Will CDI act this way? The reg/rectifier get pretty hot is this normal?

been acting up for a couple weeks.running fine then dies,no spark at plug.wait few minutes start up again runs for maybe hours.also sometimes it will run great then it starts losing rpm.will not wind up to higher rpms then it will pickup and go for awhile.well now there is no spark any time ,nothing....

I was riding my 400ex one day and when i shut it off to put it in the garage i tried to start it put again to drive it into the garge and it wouldnt start.I put a compression tester on it and its like 30 psi with out throttle and 0 psi WITH THROTTLE. when i put my finger over the hole it fell likes its pulling my finger in more then its pushing it out Has good spark.When i took it into the shop the said it had 1oz of oil in it and a tiny pit of metal shaving(TINY BIT LIKE 30 flakes) When i try to pull start (push start/roll start) it made a not normal sound and wouldnt stay running. If my bottom end is blow why would it still turn over fine, Are my valves siezed or not working properly or is my timing off causeing valves to not open in correct order with fire PLEASE HELP all help is appreciated

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?

I have a 400 polaris'04 that when in low it pulls but wont in high

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!

I have a 2003 LTZ 400 that i bought a few days ago. The quad was running fine until last night. I let my brother ride it down the street and back and i didnt notice anything etong with bike. Then my neighbors friend came over and said "can i ride it?" I said "sure" so he ripped it down the road all fine and when he got back it died right in front of us. My brother said it was dieing on him also. He also said that he wasnt using the clutch to shift. I told him he was an idiot. Im throwing that in there incase that caused a problem as well. But today i go to check it to make sure its getting fuel which it is and replaced the spark plug incase it wasnt getting spark but it is. So i started it and it was having a problem starting then i got started and was reving at idle high. So i took it around the block and it died on me a little bit down, so i try to restart it and it started so i kicked it into 1st and it kinda launched on me and started going with the clutch all the way in. Then it died right after and wasnt running right during that process and was idleing all over the place and just died and now i cant get it started it again. Before it would start without the choke or priming it. It would start real quick now i cant figure if it needs to be rejetted or something else. Air filter looks clean also. But any help would be gratelly appreciated!

Hi, I'm new to the forum but used this site extensively to solve a problem a friend had with his bike so I thought I should at least share a little problem solver I discovered. He bought the bike knowing there was no spark. He replaced the stator and primary coil also known as pulser coil or exciter coil or rotational etc., as well as the CDI, secondary coil (the one attached to the spark plug wire) along with the wire and plug. Still no spark. He dropped it off at my place a month ago to see if I could figure out what was wrong. I did all the recommended tests and everything was within specs. I checked all connections and switches, all okay. So everything was perfect but still no spark. Here's the problem solver, I devised my own test and pushed "Bell wire" beside the positive and negative pins of the primary coil inside the plug of the ATV wiring harness (see below for wire identification) leading to the CDI box. I touched the wires to the ends of a "Double A" battery observing polarity. The spark plug sparked. So I knew right away everything in the ignition wiring was good and there was a problem with the primary coil. So there you go, no ohms and crap to test, you'll know right away where to look for the problem. I pulled the stator housing and found that the primary coil (or what ever you might call it) was mounted upside down, I removed it, turned it over, remounted it and now the machine runs perfectly. Here is some info I could not find on line regarding the primary coil: The after market stator on this machine: Blue with yellow stripe is positive from the primary coil Green with white stripe is negative from the primary coil. ATV wiring harness: White with blue stripe is positive from the primary coil pin to CDI. White with red stripe is negative from the primary coil pin to CDI. I hope this information helps somebody.

Hi. I own a 2001 Yamaha Kodiak 400 4x4. I am looking to buy new rims for it. I just don't know what rims exactly that I need to get as the back and front rims have a different offset. I'm looking at the itp Delta rims. I have tires from my grizzly that I would like to use on my Kodiak. They are size 25. If anyone could help with the specific rims that I need to order, it would be greatly appreciated. Thanks
