It was popular in the 80's in Japan. Chances are unless you read japanese, you won't find much other than what I recall, or what I can look up in my old Japanese magazines. I'd love to, but offhand don't know where the issue is I need, and don't recall right now if there was any specifics on the 2300.
I think you are incorrect about your CR, the increased bore size increases swept volume, and the L24 is a flat top piston, (the Pin height is the same L16/L20A as I recall) which means your compression will go UP not DOWN!
If you get L24 Pistons on L24 rods you would pop out the deck 3mm at least! With the 130mm rod, and same pin height... you should be golden.
