jug is on. so I can now measure deck. to fine tune my head CC's to hit the compression ratio I want.
.048" positive deck hight.
Formula For Milling PistonsTop per lunati
(For 4032 material only)
Piston dome cc's to gram conversion: 1cc (volume) = 2.8 grams (weight)
This is a good way to remove excess dome without having to re-cc piston: Mill a small amount and re-weight piston until total reduction is reached.
Example:
A piston has 12.5cc effective dome volume. The desired effective dome volume is 10.5cc.
To remove 2.0cc, cut 5.6 grams (2 X 2.Cool from the piston dome.

It's gonna depend on the alloy content of the aluminum used.
Good luck finding that.
Since you know that, I can only assume that this is another test to keep me endlessly searching the internet for trivia that can't be found.
Darn you Motorrad!
So I suspect that the difference between your calculations using 4032 and the cast aluminum will be so slight as to be difficult to measure.
Then again I don't weigh things by their sub atomic densities.... very often

Perhaps you should start
Other head had been cut too much to get it up to the needed chamber cc
So
Started with a new head
And fresh off the lathe from being molested

Looks sweet as always....
Is that Dawn soap?

Yup. Best thing to happen to cylinder's and heads ever.
If bikes are for kids I'll never grow up.
