Both of these are excellent suggestions. If this KFX400 is an older one, it has TWO adjustment bolts for the axle bearing carrier. If the carrier is crooked in the swingarm, it would cause you to turn or drift to one side or the other when riding wheelies.

worn swingarm or axle bearings will make it drift to one side. a rear end that isnt aligned correctly and tires air pressure that dont match. or different sized tires
