My friend has Ranger 750 serial #129144 which is one number from the purported last Ranger (129145). Looking at the cylinder head it is the "Commando" casting as all Rangers, but the rocker feed is tapped on the side of the head like Commando rather than on the top of the cylinder head as most Rangers, including mine and my spare engine. The outer bosses on the top of the head are not milled or tapped. The rocker feed oil line appears to have been replaced with a homemade one, but the original was likely the same as the early Commando.
My spare engine is about 50 numbers lower than his and my Ranger is nearly 80 numbers earlier.
Has anyone seen a similarly drilled head? This appears to have been done at the factory as there is no evidence that the top bosses were filled or welded. Perhaps this was a mistake by the factory that was caught before the head was completed as a Commando. He has a couple other Ranger 750's, but none with this drilling.
