    Is this someone who has actual experience with Airheads? The writing leads me to think otherwise.

    I'd go as far as questioning his qualifications to work on anything that goes suck - squeeze - bang - blow -..........

    Hmm. I'm pretty hands-on, so I'd be inclined to just tear it down myself and find the real problem(s).

    Hot diggity damn! That's amazing.

    If it does look like that...unless you want/need the experience, don't even bother with the tear down except to get good parts. You've probably got metal bits in all the oil passages and pump. If oil pump gouged, block is gone. Rods are probably frozen on the crank, bearings seized, etc, MAYBE good lifters.

    Take your new engine, put a set of new rings,,,maybe a timing chain - and ride. Use the old block for a door stop.

    Ouch. This is what happens when you figure that the noise will go away if you ignore it...

    Makes me wonder how long that one was run before the owner got tired of the noise and lack of power.

    Story I got with the pictures is, a guy was riding on the autobahn at about 6000 rpm. After hearing the noise (valve seat came loose) slowed and got onto the shoulder and limped it to the next exit.:norton

    That's not the OP's engine.
    And guessing by how long that engine must have run (on one cylinder) with pieces of broken off valve in there, nothing's seized at all.
    If it had been shut down the moment it lost power and started making noise, it might even have been salvagable.

    Which was what caused 90 percent of the damage.

    Exactly, it should have been shut off at the first hint of noise and opened up for evaluation. :deal
