i was changing the valve stem oil seals on my 4x4 cossie head yesterday when i noticed some1 has scratched some marks inside, they were on the exhaust side where the rocker cover goes.
it said
47cc
cmes
now i guess this means the size of the combustion chambers but what does it work out the comp ratio to be if i have std comp pistons?
and what does cmes mean?

Can't help with the technical aspects, but on mine the guy in the engineering shop told me that my markings (sorry, can't recall what they said) showed previous skimming work had been done, so that someone working on them in future would know what had already been done.
