Always considered that being self-evident for people getting into mods...but I guess not...anyaway from my experience I can tell that a CR of up to 12,8:1 is more than enough on our little engine and will not make it suffer too much...
that is why JE, wiseco and other top notch companies make most of their designs aiming at 12,5:1
of course there are many other factors that give that stress to the engine but the most important -heat ralated especially is CR and ignition timing so people be careful when fiddling with those two...
