I took my '98 YZ 250 out to my local track to give it a little exercise, I had her wound up in 3rd gear through a turn and it started to bog down then made a little poof noise and I had oil all over the side of my boot because (from what I was told) my head gasket popped. I ordered a kit for the top end and it comes in tomorrow, I just need to know some steps on how to do it, what tools are needed, some things I should be aware/careful of, and some tricks and tips. Thanks!!!
