    yes changing water pump seals and shaft they are bad (more like melted and the shaft is f*****d)
  3. 99 yz400 here are the sympthoms high idle, it does not get affected by idle screw could get it turned on like a two stroke without much effort smells like its burning oil after running for a while it started to puff out white smoke out of engine vent hose and afterwards it started to leak a little oil thru the same hose other than that the bike runs fine but it smells like s**t, high idle but it doesnt semm to have a power loss (not that i would be able to tell the difference i bought it used about three weeks ago and never ridden a 400 before only 250) its just pretty fast. so is it time to replace piston and rings or it couls be something else after tearing it down here is what i found piston is good oil ring is not oil is not milky however the is no coolant, where did it go????? so it overheated and fried the ring but where did the coolant go
