If you turn the idle down you should start to hear a klacking sound coming from the valve cover area which tells you the auto decomp cam is tipping the Exhaust valve rocker as it should... The noise usually starts when you turn it down to around 1400 rpm or a little below...

You should also hear this auto decomp give a click when you slowly roll the engine over with the kickstart or with the rear wheel while in gear...

If the auto decomp is not working you can use the manual handlebar lever unit in it's place to help the engine spin up for cold starts... Not having or using some form of compression relief upon startup is hard on the E-start system and prolonged operation this way will usually lead to some sort of mechanical starting circuit failure...
