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?

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.
