Remove the cam chain tensioner from the cylinder. Shine a light down the cam chain tunnel and verify that the chain is centered on the crankshaft sprocket and centered on the front and rear guides. Confirm that the chain is fully engaged on the crankshaft sprocket by lowering the camshaft sprocket slightly then rotate the sprocket slightly while lifting it back up. Check that the timing marks are aligned then start the sprocket bolts one at a time. Reinstall the cam chain tensioner while using a thin bladed screwdriver to turn the center screw counterclockwise as far as it will go. Once the tensioner bolts are installed release the screwdriver and the tensioned will spring back out. Check that the timing marks are aligned. Slowly rotate the engine two complete turns and double check the timing marks are still aligned.
