If no choke is fitted then if it starts well and once its up to temp it also runs well, then its too be expected as it warms up it needs babying. There is no ECU to keep the mixture correct at all temps. So you tickle the carbs before starting to get a rich mixture by raising the fuel level in the float which you have right as it starts well. Then as the engine warms up the fuel level is also dropping and leaning out the mixture, if it leans out too quickly then the engine will falter, too slowly and the same will happen as the mixture will instead be too rich.

So next time you start the bike, tickle the normal amount and then as it starts to miss tickle for a second time. If it improves then the mix is lean, if it gets worse then the mix is too rich.

If the mix is lean then in future either tickle twice or fit a choke, too rich then apply some throttle for a min or so and live with it.
