I called it the Mystery Z. Restoration after a completely wrecked piston.

As a first bike I chose something with character. Little did I know just how much character this special Z200 has...
It's a '77 Z200 from Austria

wow, that was some real carnage in there. I'm impressed you pressed on, nice work

Great job!  It's nice to see a good bike saved from the scrap heap!

Here are some impressions. 

The video is of it running after I put together the engine again. Of course it didn't start right away but took a couple of days of readjustments, changing the head gasket, going through several spark plugs until it then finally came to life. In the video I actually started it for the second time, that's why I'm not too surprised anymore. The first time was one of the happiest moments of my life (I don't have kids yet...)! 


My working conditions in our courtyard, since I don't have a garage available:




Some of the metal scrapings I fished out of the engine. Felt like a surgeon removing bullet fragments from a body. 

Well done! Good sound!
