A long time to finish this story. As I told last year, the engine package lasted 1 minute 17 seconds. I've managed to clip part of that video so you can see and hear it run. At the end of the short video you can hear the drive start hammering itself to bits.

Lessons learned:
1. Don't gear cranks together to run staggered timing; only run with identical cylinder positions firing together.
2. Don't let two engines have separate ignition spark events; prevent gear drive back lash impacts.
3. Don't keep telling your wife "it's almost ready to go".
Maybe someday, I'll try another twin engine bike.
