I know this might have been brought up a few times before but can't find anything.
I understand that in a gasoline V8 engine a compression of about 10.5:1 is pushing the limits of pump gas.
But what puzzles me is why does my motorcycle (2008 Kawasaki Ninja ZX-6R) came from the factory with a 13.3:1 compression and ran on premium gas without any problems what so ever, also my new motorcycle (2009 Kawasaki Ninja ZX-14) runs a 12:1 compression on premium.
I also know that diesel motors (the ones I work with) run almost 18:1 then are turbocharged to insane amounts of charge PSI. I understand that this is because of the differences in firing methods.
What makes these motorcycle engines allow a higher compression then a V8 or other factory car will allow?
Hopefully someone is able to answer this, been reading alot and now I'm puzzled.
