ADA dome quick question

[DAG]

Everywhere i look the YA7633L dome says its for: Dome 215psi

Running a 62t 760 at 84mm piston on stock stroke crank and was dead on 180psi.

Is this because of the port work? or am i going crazy :thinking:



i just dont wont to order the wrong thing.

Yes various port work will lower your compression. I run 31cc and have 190 PSI.

Yes bore will also affect your compression.
