A geeky chortle

The following was spotted while browsing technical forums (fora?) related to my fourth-year, racing car project (explanatory post still in mental prodution). It refers to a Yamaha single-cylinder bike engine.
Please note you won't find the firing order in
any of the published Yamaha Service material,
and you need this info to program the ECU.
Our engine guy spent weeks chasing down this
info. We finally determined cylinder firing order
as below:


Hope this helps.
It can't only be me that laughed at that?

  2. Wow, I wonder why they don't put such a useful piece of info in the Service manual.
