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

SOURCE: We just got a 2000 Yamaha Kodiak. Idle is too low

yea if your sitting on it there should be a plastic screw on the carburetor that runs to the other side you can adjust it with your hand as it is big enough to turn by hand have it running and adjust it to your liking

SOURCE: engine stalls after acceleration

Sounds like its not "un-choking" it self, that its running like its still choked like you wold at initial start up.

Disassemble it and see if u can pysically see the activation and deactivation of the choke when u apply them.

While u are at it, also make sure:

Gas is fresh?

MIx is right?

Plug is good?

Chain brake mechanism is released.?

Good luck.

SOURCE: 2001 yamaha ttr 250, starts, idles ok, bogs at acceleration

Has the bike been stored for any long length of time?
old fuel in the carburetor will turn to a varnish like residue blocking the jets,or possibly water in the carburetor.

Testimonial: "The bike was not stored and was ridden regularly, but it still sounds like it could be the carburetor. Thanks for your insight."

2003 Yamaha Kodiak 400 back fires and kills. This happens on full throttle. What could could be the issue?

The high speed jet isn't rich enough or the carb passages needs to be cleaned. You can move the clip down one spot on the needle so it gets more gas, this will also give you more power at the top end.

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.
