well kinda... 1.5 maybe, hah... anyway so I have been running an A35 topend on my daily maxi for a while now, that's fun and all but after building up a Trac A35 combo with an Alukit and 15SHA (I really just needed any topend but cheap as they are I was like why not!?) I realized that that that little thing has some serious kick, I underestimated it. so now to my upgrade. I saw that the thing has super modest porting, one transfer not much larger than stock, an awkward booster, and a basically stock exhaust. I guess the extra 20cc of displacement is where the power is at on this thing. so I obviously wanted more... just a bit. here's some picks and explanations, what y'all think?
The booster is small, so I opened it up a bit... could have gone bigger I'm sure but I'm only gonna be running a 16SHA, with a polini 4 pedal I'd open it as much as the _Rear Feeder Port_ Before

The side transfers opened later than the booster, so I evened that out with shaving a bit off the piston where those meet... Before

After and with a window cut to make the booster stay open at BDC, it's weird the piston window was completely closed at BDC so this window adjustment keeps it 360

Piston in cylinder(halfway through transfer duration)
