thanks for the info on the moose gaskets - I was questioning the head gasket when I ut it in, but did not have anything to compare to, so went with it any ways. Over eger to ride that coming week-end. I plan to do a complete engine rebuild over the winter (between sleding). I also just picked up a 95 KX 125, so my son can ride, we'll do a rebuild on it as well, it isn't even running yet. As far as the Radator mine are two different sizes, but even so should not be that different in temp.
