Would using a different piston [if one was available] with 30mm CHP, to suit the 116 rod, have the same effect?

i then played with ignition and found an extra 1 bhp but did so on larger main jet so will try the smaller jet back in tomorrow hopefully 47.4 + 1 =48.4 but quite often u need to fuel the advance so maybe not?
still so much to try,i have different petals both thickness and weave,boyessen stuffing,more port adjustments,compression adjustments,flywheel lightening,different carbs,carb mods,intake tract lengths,plug grades and types as well as a few pipes to test and pipe tricks
then i have to start again with the 72mm ts1 version ive just finished
