In Reply to: how to measure cylinder head volume posted by George on Monday, December 10, 2001 at 10:56PM :
I use a piece of plexyglass with a 1/8 inch hole drilled in it.
tip your cyl. head upside down and use some petroleum jelly to stick it to the head to cover the combustion chamber.
(note:use a level to make sure head is sitting square on your bench.
next use two siringes ,one about 50cc and another 5 to 10 cc.
inject some colored water into the hole in the plexyglass taking careful measurements of how much fluid you are injecting.
use the small one to finish filling the chamber.when all the air escapes then add up how much fluid and that gives you your volume. note:always have the spark plug in place and tight.
