Well I finally figured out what happened to my warrior. I thought I had dropped the intake valve but upon further inspection, the rocker was bound on the shaft. Good news was the cylinder and valves were fine, bad news is the cam, rockers, and rocker shafts were toast. I have come to the conclusion that the oil pump must have died b/c it appears the bearings were dry. This would also explain why the previous owner just did a top end rebuild only to get toasted 2 months later.
I do not know if the intake valve lock nut coming off was a sign of lack of oil but I will be replacing the oil
Thanks for the help.
