Standard size 240/270 UT 2 Honda piston.

You know which bore? 240 is 72mm and 270 is 77mm.

Come to think of it I don't know.........I ran number in a search and Boat net give this response......working on cross ref. with honda manuals.

Tracked it down to the same piston used in a EB4000x Generator engine and it has a IGX 270 Engine.

Huh. So it's both ways. It's confusing now! Lol

Did you find that number on a 240 72mm piston?, I cross ref. everything I could find....maybe honda use same number and designates it by size.........don't sound like Honda but who knows.

If i'm not wrong, newer 240's and 270's are both 270cc, but the carb makes the difference?
