the same thing happen to me I didn't tork down the cam bolt and when I started it up the blot came louse and the sprocket slid back and it looked the same as yours. what I did is I put a spacer that fit tight into the sprocket and also fit tight around the bolt. But the spacer cant stick out...
I remeber when I first got my warrior and it would start up and run but when I lay the throttle down it would just pop pop pop and pop and back fire and it just had no power and what I found to be wrong with mine was the cdi ignition box was bad I replaced it and Now it revs high and lots of power.
hey I'm going to open the transmission when. I open this up is there anything that I should know I'm going to lean it on its side but is there and springs or anything that's going to shoot out of there when I open it up.
