Deck Height Question

[Balzout]

If .030 is the minimum squish before the piston starts to kiss the head, would this hold true for the top ring also? How close can you run the ring to the top of the cylinder?

i run the vito's pistons the rings are custom cut 2mm lower to bring the heat away from the rings .

Interesting. I'm new to the two strokes and thats something I've never dealt with. Is this common to do to positive deck height motors?

Well lets try this one, since the pistons are up in the domes about .100, are the domes supposed to be cylinder diameter?

yes

bump for how close can you run the top ring to the top of the cylinder? thanks

well, at 5mm, the ring pops out, usually. i'd have to say, you want to keep the ring 1.5 to 2mm down, but that's just looking at all the different setups i've seen
