He does good work. Thanks for posting. He also did a bunch of car engines if people are interested.

EDIT:
My favorites are the VR5, Yamaha crossplane and big block Ford. I like flatplane V8 in real life, but it doesn't sound great in this demo.

That's pretty cool.

Bike engines with exceptionally odd firing patterns ... Honda RC211V (5 cylinder with the middle cylinder on the front bank having a crank angle offset a specific amount from the others), and the new Ducati Panigale V4 (90-degree V4 but with the crank pins 70 degrees apart and the cylinders on each bank firing in sequence 90 degrees apart - not the more usual 270 degrees apart). All cylinders on a Panigale V4 fire in 380 crank degrees and then there is a 340 degree space.
 
wondering if the Harley one is accurate for a single crank pin 45 degree twin?
doesn't sound like the bang-bang, make a sandwich, bang-bang, eat it, firing order to me??
 
H-D firing pattern is on alternate revolutions, not 45 degrees apart on the same revolution, so the firings are separated by 315 degrees then 405 degrees...although it seems common to be cough sputter BANG misfire sputter bang bang cough misfire BANG and so forth...

A 6 year old told me once that "if you cough,burp,fart,blink and hiccup at the same time" you'll die.Hmmmm?
 
Wonder if he'd take requests. Maybe a 65-degree bank-angle V4 with a 180-degree crankshaft throws, for instance...
 
Noise not withstanding, there are differences in the way engines/bikes react to different firing orders.
IE The Ducati twin firing order lets it accelerate out of corners better, like a two stroke.
