I was just reading up on a drag race/veteran/engineer named ed donovan, makes racing aluminum engines.

he made a four cylinder to have 5 main bearings, four bolt main caps...because it needs all of it. today, all four cylinders inline are that design...but with two bolt caps or insane japanese mitsubishi types, still committing suicide to performance...anbd 25psi boost too much..just to make up for its own wobbling mass, like a jackhammer..

Aside from having my last name.. it occured to me. They are all crazy.

leave that darned inline four alone..not even a v-twin harley with momentum keepers can keep an engine going for long. An inline for is extremely set and proprietary with balance.. it is hopeless. Save time and money, and leave it alone with all four banging, ya know, up and down up and down with a hopeless hollow backside already....

I have said it time and time again..the ONLY four cyl that can run on two cylinders and survive.. is a 3 main bearing boxer, with one timing belt removed...and ya know..that is just plain ol ridiculous... a four cyl takes the linear to a revolution at a zero degree loss..that is as small as it can get to maintain fantastic efficiency.

I do not type this to be mean to ideas.. given my own path and past.. it is just outright ridiculous to ponder.
