My KDX is only revving about halfway through the RPM range when I first start riding. After a few minutes of riding, it will revv all the way. Could this be a carb issue, power valve issue, or something else? Thanks.

What have you already checked and eliminated as possible causes?

Okay. I'll pull it apart and look at it. Would it be sticky because it's dirty or for another reason?

They just gunk up over time and need cleaned periodically. Too much premix will make them gunk up faster.
