I agree it looks like you have a broken rocker arm , but I also noticed that your timing gear is not set to the line , you could be inbetween your cam lobes , make sure you have everything set to tdc and all your timing marks are inline then set your tappets clearances , you can pick up a feeler gauge from the hardware store for $10 to $15 bucks I would suggest you invest in one . my warrior makes a ticking sound as well but that's seems to be pretty common with warriors , but the play in your rocker arm is to much . like it was said before grab a flashlight and look and see if your rocker arm is broken . they are real easy to replace .
