my bike dose not have a choke at all it runs a richer fuel mixture for easier starting.
it is older 1974 and it runs a lever to lean out the fuel mixture at lower revs when the motor warms up to stop it from flooding at idle.
and it can be tuned to even over come that but it gets technical.
my bike starts first kick due to it air fuel mixture, yet some bikes do not.
if for example at idle the motor revs high, can mean that it is hot or the air fuel mix is to lean, but if it is cold the motor will not run, so the choke is used to richen the fuel to air mixture by slowing the air flow to make the motor suck more fuel.
but the downfall of running a richer fuel mix is that for example it can not allow the motor to rev freely, as it like lighting a gas stove or oxyacetylene is a better example.
it is easier to turn the gas to full and have it explode than to try and light it as as low as it will burn.
so you start it rich and lean it off, and like a gas stove some will go out if you try to do this straight away, so then you need to do it again slower.
i have no idea what part of the world you live, to if it snows or the you live in full tropics with humidity.
as these extreme weather changes a choke is needed in the cold but in the tropics not realy at all.
for me we all ways used to pull the chokes out of our cars as we have no need of them and when they are automatic they are just bits of 5hit.
and a complete waste of fuel and time.
