Why is it called...

An open modified small block kart motor is called a 14.5 cu in....why isn't called a 237.612 cc motor? To my knowledge all 4 cycle engines used in this class are sold as whatever cc they are, 196, 206, 212....etc....is it an attempt to confuse or is it something else?
 
The original flathead briggs were called by their cubic inches.
A stock flatty (model 13 (130232)) was about 13 cubic inches

.100 overbore, .200 over stock stroke was more than14.5 cubic inches.

Holdover from old days.

Some of us still fight the metric system.

I like to thank President Carter for starting us down that road, but not forcing us to go all the way.
They still build modern cars, equipment, etc using a combination of bolts, wrenches that keeps us tied to both systems.

The highway department of our fine state started to convert all highway plans to metric, but switched back because it caused confusion in the engineering department when looking at old grade plans and making match up with new designs.

So, we get a mix of plans from that era, with newer plans back in standard ft measurements.


No one really calls out elevations in meters.

Usually ft above sea level.

Well what is a 196? 206, 212? … wait for it.. cc’s The metric system.
Yes 196 is cc but that's because the clones and Hondas are made in china and Japan vs the Briggs which are American and in the briggs manuals it states the displacements usually in CID
 
May be in amerca but all dirt bikes and fourhweelers made in the US are measured in cc. All motorcycles are measured in CC except for a few. There is not a one size fits all per say for measuring engines. But these are chinese motors and there trying to measure in CI vs the Normal CC measurement.
Correct, i just posted that as a joke

Per the generally accepted rules
Thats the maximum Displacement.
 
WW-2 Harley Davidson 45 cubic inches
Panhead 74 Cubic Inches .
Shovelhead 74 Cubic inches
Not all motorcycles .
Harley is only one I know of but I didnt know that they had CI measurements on there motorcylces back then but that is cool to know I am always satisfied by a loud harley. I dont know much about other motorcycles. I only care about 2 stroke dirt bikes.

Are yu confused?
 
Maybe we're just in denial, that in reality we've sold out to China?
I'd suggest that we go back to running flatheads again, but you just know that won't fly with karting today. ;)

All of our prints are written in standard, they use 10ths for elevation, something that confuses many
