Let's see Bad Obsession do this...

Yeah, I know it would have been easier to just buy an engine, but it's still fascinating.

Check out Allen Milyard

 

This gentleman is the master of adding cylinders to motorcycle engines.

He makes it look so easy !

That's amazing. I can't imagine the thought going into figuring out it would be best to rotate the cylinder location, the machining inside the cases for clearance, the split plates he's using to support the main bearings. The tolerance stack of gaskets between all the cases. I'd be so worried about would the transmission be able to handle the 4x output? Would the single timing chain be up to the task? Stress full.

How is he going to run spark plugs, or wires?

In reply to Run_Away :

Yeah, I was wondering about that, since the heads cover access to the plugs...
