That's not SV650 engine.
I know,I own a SV650
According to the description it's from a Suzuki Savage.I'm guessing it's the same motor as the DR650.
It looks like it's also running a belt final drive
The Savage had an engine all of its own, it's even more gutless than the DR650.
Alan Millyard's Flying Millyard has an engine made from two barrels and pistons from a Pratt and Whitney radial aero engine. It's 5l, the pistons are huge!!

There is a world of difference betwixt a rotary and a radial......
So much so it's enough to make your head spin.
And the crank case (but not the crank...).
Early rotaries,like Sopwith Camels, have the crank stationary and the cylinders spin, but someone worked out this was stupid, and on most rotary engines the crank spins and the cylinders are stationary.

That's the difference between a rotary and a radial engine, the cylinder layout is the same.

It wasn’t stupid at the time. The rotary had a high power to weight ratio (compared to other contemporary engines) and didn’t vibrate the airframe to bits.
It was overtaken by developments in radial, inline and V-configuration engines.
