I wanted to know if anyone’s had experience switching from the stock 4 degree crowned pistons on their TM KZ or ICC motors to the aftermarket(Vertex, Meteor, etc) flat top pistons?
Theoretically there should be gains with the flat top but has anyone noticed an appreciable benefit? What about the lighter pistons offered, or the combination of the two?
How does the flat top affect the squish band? If ~1mm (.039”) is a good starting point for the crowned piston what would it be for a flat op?
Finally, I know the head insert/combustion chamber has to be changed out or reworked as well, but I would think the the actual cylinder head would remain stock as it doesn’t have an effect on the shape or volume of the combustion chamber.
Thanks for sharing your thoughts and experiences
