Hard cut = 18a
Soft cut = 16.5a
When the throttle is @ WOT, look at the TPS position for demand. 0 to 9 = 10. So 10 is the demand, 0 is closed throttle.
When the engine is @ 0 or fully closed throttle, the injectors are on the engine side of the throttle plate, not on the opposite side of the throttle plate. So fuel enters on a closed throttle.
0-throttle + 0-demand = 18a, I'm going to cut fuel so the idle returns. Idle returns it's @ 14.7 or stoich in open loop. A certain hack will bring the cut to a richer 16.5a and no pop out the exhaust so much = Close PAIR.
The fueling feeds in a constant microsecond, millisecond, ect., and never shuts off fuel= EVER! So, lean it goes and burns pistons, as the fuel is shut off? Nope. You just see the AFR in a lag between execution and time to when it reaches the AFR meter. The number on lift is set at about 18a to 22a in the lean setting. PAIR off, that fuel is 16.5a and is still showing a fuel burn.
Throttle position + RPM = Fuel trim delivery by all telemetry ~ no codes.
Coded + RPM = Fuel delivery in 'Method' ~ No TPS sensor connected.
RPM + Method = Fuel deliver still in binary calc = Still in a 14.7 stoich setting.
14.7 psi = Always closes at this pressure no matter rpm. The AFR is Air(14.7) to Fuel(18a) = Lift trim = 0 throttle input. So the TPS being a rheostat has many analog numbers entering up to WOT. The bike's rpm still has to move one 360 at a time to gain 1 rpm at a time in a linear state.
123456789 = 10 is WOT. 10-987654321 is = Lift. It still has to incrementally fuel each rpm on the slow down of each fire, or pure oxy would create heat (kinetic) and not be able to cool it slightly with 18-22a? She burns up.
Conclusion:
The crank is in a 4-storke move as long as that back wheel is propelling you down the road.
The crank is in a constant suck with throttle open or closed. The air ratio is a constant 14.7 of pressure closing.
The crank is in a constant rpm change but in a linear up/down movement. Every stroke is fed a fuel, does not shut off, nor can you shut off that void as long as that valve keeps closing on the Penultimate number.
The crank is in a certain rpm position. That rpm is in a lift/wot/sustained environment. So fuel is a constant.
The crank is sending in a fuel signal to match crank speed. The method takes that data of speed and calc's off of rpm rotational speed, no TPS in play = Method.
So be it OE or Backup, the ratio is displayed on the AFR meter as a constant fuel metering to both cool the engine and have the transition of fuel flowing in an uninterrupted event. If fuel was cut, you'd nosedive, have the bike sit up; no power to push forward... hit the kill switch to see what I mean, when someone says no fuel on lift.
