Then how do all those Honda & Kawasaki 180`crankshaft vertical twins currently sitting in showrooms manage?
Same solution as the Hinkley Bonnevilles & S.G. 961...balance shafts...
Ok?....
 
Is that animation one of yours, Rohan?
Have you looked at it?
It is crook...crank throws are uneven...L.O.L...
 
Are you purblind? Look closer, since when do pistons in a twin have differential strokes....?
 
If you put $$ into this, maybe you could ask for it to be corrected.....

Rohan, mind your tone, I refer you to J.D.s recent reminder ..
The horizontally opposed BMW twins fire the same as a Commando...but being 180`twins compared to 0` as the Commando is, they run a 180`crank...
I asked if anyone had seen one set-up to run a 360` crank, which would be a firing configuration equivalent to the 180` vertical twins.
OK?...

The BMW motor fires the same as a Parallel Twin but as almost perfectly balanced apart from the rod offset 'rocking couple" its very smooth. although both plugs fire at the same time ( wasted spark) only one cylinder is producing power.
Other than the rocker cover touching down on some corners
