Just wanted to let warrior owners in a potetionally expenseive problem found on warriors... the nut that holds the sprocket on the cam has been known to back off from vibration and causing major problems.. it happened to a friend of mine twice.. the second time it let the cam chain jump time and threw a valve straight throught he piston... then pieces of metal fell into the bottom and broke the cases... i've heard of the same thing happening to other warriors too... keep checking it for proper torque or just put some locktite on the threads and retorque it
