Wow, what are we back in the 40's?
Jap is an English abbreviation of the word "Japanese". Today it is generally regarded as an ethnic slur among Japanese minority populations in other countries, although English-speaking countries differ in the degree to which they consider the term offensive.

Intake closing, chamber shape, play important roles in the compression needs.
Take a look at the compression needs of an S&S .675.
Have a 124" on deck with the use of one of those.....again.
Evo .715 Red Shift from yesteryear also.

Look at the piston size and travel distance difference between the 2 engine designs a few things should become apparent to anyone who understands basic internal combustion mechanics. Trying to compare the 2 is the age old apples verses oranges argument.

My Limited is liquid cooled???????????????????????????????????????????? ?????????
I've done a bit of research on this over the last few months. The quick answer is that liquid cooling, total ignition advance, combustion chamber design, piston crown design, and cam/injection timing all play a part in allowing the metric bikes to have much more radical CR than the Harley equivalents.

sad to say but in this world we are living in, too easy to get offended. yes language evolves for ex: the so called "n" word actually had nothing to do with what it is now associated with, actually an ole 18th century word for a bum mostly associated to the white man but could apply to others.
my take is, call me anything you like just don't call me late for supper!!! if i answer, i answer but if not, pull the wood off the fire, it goes out, hummmm, doesn't the bible and most other religious writings suggest the same??? a child is not born with hate, it is a learned trait.
panties in a bunch, post an address and i will send some boudreaux butt paste.
