Can anyone advise me of the volume of the combustion-chamber in a 1275cc motor.(likely a motor exported to New Zealand ).
A modified-head from a 1098 that I used years ago has combustion-chambers of approximately 24c.c. and I am wondering if using that 1098 head might push the compression-ratio too high for road use.
Any suggestions would be appreciated as my mathematical talents are about the equivalent as a constipated-mathematician, who had to work everything-out with a 'pencil' !

1275 (all) = 21.4cc
12g202 (from standard 1098) = 26.1cc
12g295/206(performance 1098 Midget) = 28.3cc
