Hey guys. As some of you might know I have a 07 kx 250. The previous owner had a 168 main jet in it when it is 160 stuck so it was obviously fouling plugs and was gunked up. First thing I did was clean up then cylinder and rejetted it. It fixed the bike for the most part but the power valve leaks oil out of the breather and im curious if this is normal as i dont recall any other of my two strokes doing this. Now there is no spooge coming out of the muffler and aside from me busting it, the packing is fine. Now I had the pipe and silencer welded back up with new backing and now it sounds a million times better. The bike has oil dripping from the breather all over the garage and it is annoying and I would just like to know if its normal. The bike runs fine aside from that.
