He must have been haulin ass if he was "winding his yz450f out" on the vintage track. The straights are so short (except for the front straight) how can you wind a big bore out. I've wound 250fs out there but never a big bore...then again I'm a crappy rider :thumbsup:

Obviously a lubrication problem. Low oil level? What kind of oil and filter was he using and when were they last changed?

I was thinking the same thing. A buddy of mine had 4th gear wrapped on a straight away, and when he downshifted for a turn, it just bogged down and killed on him. He was terrible about keeping everything up on the bike, and he hadnt changed his oil in months. And just like yours, welded straight on.
