warrior rocker seized

[projectwarrior]

ok now i bought an 01 warrior with a bad head,, it had a fresh rebuild and a web cam. He said he rode it for 3 times then he was cruisin and it shut down and didnt have anycompression, turns out the valve was bent and messed the cam and gear up real bad.

So i bought a head from a 88 warrior and put a new stage 1 hot cam in it put it all together and rode it for about 3 hours, no problems and i was goin about 45ish down the road in 6th and it make a faint noise and died with no compression once again. tore it down an it has a seized rocker, form lack of oil i found out on the exhaust side? maybe there is blockage from when the old head went? b/c the head bolt on the intake sde wa nicly soaked with oil and the other only had a little bit?

i know alot about engines but im kinda stuck with this any suggestions are appeciated, thanks Adam.

for sure a lack of oil to the top end.
Some things that can cause this are the oil pump, some blockage on the intake side right side head bolt (the exhaust side is re-turn oil), intake oil pump filter, oil filter to name a few.
Some things to make sure of is that you have oil pressure at the plug on the top of the head next time when you go to run it. Also I would tear it down again and see how the piston looks. You could need to rebuild again. I would go and put a little air pressure to all the holes to make sure there clear. My guess is though an oil pump...

yeah its tore down and the cylinder is still fine.. i didnt take the filter off yet but i am going to blow air through all the oil passsages, il be sure to open that little screw at the top when it gets going again to check for pressure thanks
