Hay Guys, Looking for some help trouble shooting my 2004 Kodiak 400 4×4.
Last ride out it was puttering and loosing all power while climbing hills.
On flat ground and in neutral it starts,idles and runs great, until the throttle is maxed and it will putter and choke out making me think its a carb or air gas mixture problem.
this is my wife’s Bike and she says it has slowly been getting worse over the past few rides.

So far I have ran ATV gas treatment and changed the spark plug with no change. If I tear into the carb what do I need to look for other then basic dirt and grime? I also installed a UNI air filter a few years back and didn’t notice a problem but have been reading how they may provide too much air?

Also just to check it out I opened up the Cvt and the Belt looks good, no cracking and thickness is fine. Primary and secondary are a little dirty but nothing major. (I don’t mud my Atv’s).

Are there any other components I should be looking at for this problem?

Thanks for any info.
