Hello All!
I recall looking at adds made in pre-wwii for cars and motorcycles. One feature that was praised and shunned was tapered bores.
I tried to find some info on tapered bores, but all I found was information about straight bores being tapered due to wear.
When intentional, what is the advantage of a tapered bore?
Is it wider near the head or the crank and by how much?
Does the taper go away when the engine heats up?
Was it intended for non-ringed pistons?
