smallport compression ratio ??

[haado gei]

the stock compression is 10.3 or 10.4 but i am asking is there a way to find out what the compression would be with the 0.5 and 0.8 trd headgaskets ? thanks

You can do it with basic maths. You know the stroke, capacity and compression ratio, so you can work out the area of the bore and the combustion chamber volume. Then you can work out the change in combustion chamber volume with the thinner gasket, and from that, the new CR.

Not hard. You can even use Excel to make it easier and make graphs.
