This is a 2011 Harley Davidson Electra Glide. At only 30,000 mi the automatic compression release (ACR valve) in the rear cylinder head stripped out of the head and caused the exhaust valve in the rear head to burn up from running to lean. We removed both heads cut new valve seats and replaced both exhaust valves. We then squared up the heads in the drill press and installed time serts for the ACR valves and installed new ACR valves.
