Your carb needs cleaned/adjusted. your float could be set wrong. could be an air leak somewhere.

SOURCE: klr650 2006 not idleing good i have to keep the choke on a little

choke gives it less air more gas. but sounds like when you turn the handlebars you are pulling on the throttle cable somehow. check that it's all run right, if not tru tugging on the wiring harness that runs between the forks there may be some kind of short there,

SOURCE: Mikuni carb stuck in full throttle. Everything's

Most modern Yamaha bikes have a throttle "Push-Pull" system. You may need to make sure that the "push" cable is actually set up correctly. Your manual will tell you the exact slack required on both cables. Without both cables operating your carb will not be able to close.

SOURCE: Put new carb on my 97 Yamaha kodiak 400, starts

Check your base gasket on the carb.

Testimonial: "The base on the carb is tight, not sure if it's getting to much gas or not enough going from half to full throttle when it starts blue smokin and cutting out and surging"

SOURCE: I did a full am detailed carb cleaning an tank

Lindsey... your problem is the classic issue with plugged jets. Specifically the low speed speed (pilot) jets are clogged. With the carb removed and the float bowl removed, and the float also removed, you'll see generally two sets of jets. Usually the one in the center is the main jet and has a larger hole and that jet doesn't usually clog but to be sure remove it and inspect the opening. If you can't see light then it's clogged. The more suspect issue is the pilot (low speed jet), usually off to the side. This jet, once removed has a longer body and this is the jet that is clogged. Perform the same "look thru" and you'll see no light or very little. When this jet clogs it displays the symptoms you mention. As you give the bike throttle, transition from idle thru low speed and then to main jet occurs, based on rpm and throttle demand. The pilot jet doesn't allow transition and the bike falters from about 2000 to 5/6 k rpm.

So how to clean. I've tried acetylene torch tip cleaners but most are too big. If you have an air compressor, try blowing high pressure air thru the jet and it may clear. The ultimate fall back is a chemical clean. Place the jet in a ultrasonic tank or purchase Berryman's carb cleaner in a small tank (1 gallon) (Auto Zone or internet)
and soak the jets in it. Here's another potential problem... the pilot hole in the body of the carb may also be plugged so while at it disassemble the soft parts from the carb and treat the carb body (no soft parts) also in the carb cleaner. Usually about 1 - 2 hrs soak removes the clog. Best to clean all holes in the carb body with high-pressure air. Since you have a four cylinder then you must perform the same exercise 4x. This will solve your problem...

Good Luck... Dio

2000 Yamaha Kodiak 400, was running fine and in an instant it went to half throttle, starts fine idles fine. been this way for 2 years, I run it almost every day, air filter is clean, new plug

Sounds like a frailed throttle cable, or that it might be rusted or mucked up with something. Would undo it on carb and see if it has full throttle movement on the cable. If you have not done this yourself before best to have it done professionally or do some read up good luck hope this helps

Is there an idle screw on a 450 kodiak it started to idle to high and can't select gears

probably not an idle problem but a failing throttle cable jamming in the outer case and not letting the system back to idle position

Kodiak 450 idling to high to engage gear

Have a 1994 Kodiak 400 and have no fire to coil and no spark what do you think that is

It is most likely gonna be the cdi inside the motor. Those are famous for going out. It's not a bad change tho. The part is about 250 dollars and you'll need a new gasket and oil. And really that's all.

1998 Yamaha Kodiak 4x4. Why doesn't it start?

Do it start on choke only and will not run when choke is off. carb need to be dip and soaked in carb cleaner , Note Completely apart no rubber or gasket in this solution. Blown out after 4 or five hours of soaking and reassembled.

Kodiak wont start

Run a compression test (3-5 seconds) , with throttle closed, then repeat with throttle open. Should be around 100 psi closed and 125+ with it open. This will give you more direction.
