ok
i got noisy valve train.
when you go to check the valves on top dead center they are good, when you turn the motor a little past the rocker arms are really loose.
it runs good .no miss has good compression.
what happen was riding hard and out of nowhere started making noise.
any help thanks

but why are they tight on top dead center where you adjust them
and then when turn the motor say 20 degrees past they get very loose .

Are you sure you are at top dead center? You could be 180 degrees off and the piston is really at the bottom. When both valves are closed, both rocker arms will be loose, AND the "T" should be visible thru the peep hole.
yes
and all maks lined up
valves adjusted to specs
it is when you past top dead center they become loose , like 20 to 30 thousands loose and the valve opens.
when it is running it sounds just like a loose tappet.
could it be something else causing the same noise

No not 180 off, 360 degrees a full turn of the flywheel.
You could adjusting your valves on over lap and not compression. When you have all the marks lined up the piston both times will be at TDC in the bore.
The simple way to do it or to double check is either pull the cam cover off and look at the mark. Or as you rotate the flywheel counter clockwise you will see the exhaust valve starting to open if you were on the right stroke.. compression. The next stroke would be exhaust. If you were on the wrong stroke, which it does sound like you would see intake start to open.
You should have about .003 intake and .004" exhaust.
The warrior does have a tappet noise when warmed up more so then other engines.

ok understand.
everything is line up ,on the right stroke.
the valves adjusted
it is when you turn the motor a little bit the valves get very loose.
(mainly the exhaust valve)
my question is why?
something has to be wore somewhere in order for this to happen.

I agree.. the cam has to be worn. If you turn the engine over on over lap the engine will be coming off of exhaust and going to intake. You can actually see the valves moving. So if you adjusted them on over lap and start turning the engine over you will see the exhaust get very loose.
When you set the valves the first time where they loose or tight?
