2003 Yamaha Kodiak 450 Maintenance

Recommended Posts

I'm new here. We have had many offroad things quads and dirtbikes (i race dirtbikes) but I just don't know about a 4 wheel drive quad. Well we just got an 03 yamaha kodiak 450. It has 730 miles and i can't remember the hours right now. Looks brand new other than part of the tank decal torn off. It even has brand new ITP mudlite tires. My question is what is the normal maintenance for this thing. Including differentials, oil, and how often to check valves. And are there any grease fittings i need to hit with some grease? and how often? thanks

Your compression is suppose to be high,I think around 150 to 170 psi and you need 89 octane gas,I change my oil and filter about once per yr but it is according to how often and how hard you ride,you can find the grease fittings by looking,you will see them if they are thier.

I have looked around the wheels, steering, a arms and swingarm and i don't see any grease fittings. Also it has itp mudlite tires, they are one size up and have the 1 inch cleat, will they wear out the cv joints and wheel bearings faster?

you need to run 93 its the best for it and with you having the bigger tires it will wear out the cv joints and bearings faster especially if you ride in the mud

another good tip is go on ebay and buy a manual i recommend chilton but you can also get it on a cd and download it. the manual tells you all this the cd costs around $7

We have already ordered a factory manual, and it won't be ridden in the mud. how much faster will it wear? and how often should i check the valves on it?

First off, welcome aboard! I used to have a 2005 Kodiak 450, great machine.

I agree, use 93 octane fuel. Depending on how hard and often you ride, I usuallly change the oil at least twice a year before the cold weather and once before the hot weather.

If you ride allot, change it every season to once a month.

ok, and i noticed on the cv joints from the engine to front differential there are some grease fittings, we tried to use a regular grease gun to get on them but they won't fit in there, do we have to take it apart to get to those grease fittings on the cv joints?

we had that and we couldn't get the adapter, the silver part through the joint to fit on the fitting, no matter how we turned it

I finally popped it on there and gave it a few squirts of grease, a little came out 2 of the seals but not the others, is that normal? and on the other one that is at the differential it came out one of the seals easily, and didn't even come out of the other three.

I would say that the seals that grease came out of are just weaker than the ones that held, or the seals that didn't seep any grease were just further away and the grease never reached that far.

      Heres my story. Kinda long. I guess I was a late bloomer when it comes to quads. I had never ridden a quad in my life. Rode Dirt Bikes as a kid growing up. Back in Oct of '06 I found a Mustang on craigslist. Took it for a test drive one morning before work. Fast car. 351 Cleveland. I had planned on meeting the guy again after work. For some strange reason thats still to this day beyond me, I stopped in Hillsboro MotoSports on the way home from work. I had 6 Grand on me. There was a left over '05 sitting by the front door. It was on sale for $4999. It was $5499 OTD. I didnt even look at anything else. I knew nothing about quads accept I thought it really looked coool and I had the money in my pocket to buy it. I was sitting on it when the salesman walked up and asked... "Can I help you?" Without hestitation I pulled 60 Ben Franklins outta my front pocket and said "I want this Quad. Load it up in my truck." It was just about dark by the time I drove away from the shop. BTW, I didnt bother to ask my ol lady if I could buy it. LOL. Anyway, I took it by the house and showed her. She was kinda stunned but not mad. We drove over to a friend of mines house and unloaded it. I took it to the field across the street from his house. HOLY CHIT!!!!! I was surprised by the power. I had it for about 2 weeks and took it to Sand Lake. I was there a few hours and rolled it on a banked turn at the top of the bowl right before you get to the one-ways. When it rolled, I flew off and landed on my belly. The quad came bouncing and landed on my back. For a month I couldnt even walk. I was scared of it. I considered trading it for a 250EX. Went back to the shop. The salesman said..."Dude!!! You dont want a 250EX!!! Trust me. Just get used to it" I still wasnt convinced. I put it on craigslist for $4000. Calls were coming in. I had a guy that wanted to come look at it that evening. I decided to take it for one last ride at Browns Camp before I sold it. I was still afraid of it. After about 5 minutes I started feeling comfortable on it again. I decided right then, I loved my Honda 450 and would learn how to ride it instead of selling it. That was late Nov of '06. Work was slow for a Painter in Oregon. My new job everyday? Going to Browns Camp and ridding my Quad. I bought my Girl Friend an '02 Blaster. I rode my 450 for 4-6 hours almost every single day for 3 months. And yes, I know my way around Browns Camp pretty well. LOL. In March I bought her an '06 TRX250EX (Thank God I didnt trade my 450 for one of those) LOL Since then, I have become totally addicted to quads. I love them. Couldnt imagine not owning at least one quad. Luckily I have two. My "07 was $6500 OTD in July of '07. Bought it for my Girlfriend. Traded in her 250 EX. A month later we broke up. So, I wound up with two Honda 450's.

      Hello, I just bought a 2006 ttr125 and the guy said it needed a new carb because gas was leaking out the overflow and he couldn’t find out what was wrong with it, I opened it up and messed with the float and I couldn’t figure it out myself so I just ordered a $30 carb off of amazon. I installed it and it seemed to run great around the yard but when I got on the road and started picking up speed it seems to just turn off once I slow down and down shift. I don’t know it’s like if I go to fast it will just completely die and right after it dies it won’t start, the es won’t work nor will the kick start, I have to wait a good 30 minutes before I can start it and it runs fine again. Anything helps! Thanks

      What is the opinion on carb kits? What's one of the better brands of aftermarket? OEM is always preferred but not practical, chinese cheapie is never a good option. 
      Thoughts ?

      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!
