My yz465 starts up and runs sharp, but after a lap or two, the rpms start taking a while to settle down. At that point, at a stop, if you snap the throttle and it revs right away but sort of floats back down to idle. It sounds all sorts of angry on the way back down to its idle. Sounds like a lean conditon right? Maybe something sucking air, but only when warmed up all the way? Maybe the jetting is too lean and works well for only until operating temp? Thanks in advance!
