A whole lotta theory in here. Everything works in theory...................but no one lives there.
Some engines benefit from long rods due to small bores limited by flame front speed and the longer rod will help. It carries a few negatives with it,higher weight,increased acceleration rates and a few geometry related items as well. Modifications of that type are best suited to those with the time,money and experience.
You can spew BMEP,MBT,A/F-R and all sorts of factors. They have merit however are not the end all in the quest for speed and power. In a everyday bike well tuned stock is the best compromise between power and longevity. It is truly rare that the designers and engineers get it that wrong.
you don't see luggage racks on a hearse..........act accordingly
