Hey all-
Does anyone know compression height spec for euro 9.7:1 b25 pistons, or how to identify them? I'm trying to discern if a set of replacement pistons overseas are 8.8 or 9.7:1 before I order.
US Spec 8.8:1 as far as I can tell is 34.2mm. 206.7-(75/2)-135=34.2mm.
This measurement also doesn't take into account the dome of the piston above deck, so perhaps CH isn't helpful?
I found measurements of 34.090 on Yenmax 3104600050 b25 pistons.
Yenmax specs:
Help?
