spize909 stickied topics in every section contain FAQ's

You don't list much info concerning your quad so it's hard to say. If it is bone stock it is likely not a jetting issue. If you have recently changed something (mods, altitude, diet, etc) it very well could be. More info needed.....

Here's the link to the data base. Compare how your quad is set up to what is listed and check your jetting against that.

jetmech25 The only fuel filter is inside the tank, attached to the petcock. The carb shouldn't care what gear you're in, so I assume it's just a heavy load condition. Have you checked the jetting database?

I have a 06 kfx 400 and it isles fine and runs fine in 1-4 gear but in 5th it bogges out and dies. I have the petcock and the carb. I don't know what to do next.
BTW(where is the feul filter tried to find it and just can't)
Thank you
