There is a cam chain tensioner adjustment under the exhaust pipe right at the head. I removed the plug and used a flat head screwdriver to turn it both directions to try and get rid of the "peck" from the chain. It didn't help the sound, so I am thinking it needs a chain. Just trying to figure out why the exhaust rocker is not moving, and the pushrod is not traveling. Going to have to tear it down I guess. It just had a top end rebuild right before buying it.
