Wayan, do you know what the compression-ratio is after upgrade?
Have you done a compression-test?
Do you have photos of pistons?
Thanks.

The CR is 12.8, up from the stock 11.3 my mechanic did a displacement measurement to check that.
I neglected to take a picture of the piston cause the brand/SN was removed, and it basically looked the same as most 4 port cilinder piston, lol
