I’m looking at the
Ecotron fuel injection
Ecotron vz21 turbo
Polini 125cc to 198cc big bore kit

I haven't done the turbo deal but I have done an ecotron efi my big issue was juice for the efi fuel pump.remember most of these scoots don't have much extra electric left over after running the the lights

So what did you do upgrade lights to led

No in the end I found that the yamaha vino was a full dc bike and swapped the wire harness over and stator that was rewound for more output

Now if you go over and read threads about the genuine stella they talk about floating the ground on the stator and getting a diffrent regulator to co vertical to full dc and get more apps out of the system

I don't know the electrical system on your bike I have no idea if it is all ready a full dc bike or if the headlights run on their own lighting circut plus I have no idea what the actual out put is of your charing system between dc and ac if not a full dc bike

Full dc the headlight will come on when you turn the key on and the bike isn't running

You should try and find the service manual for your exact bike and see what it specs out for output and the add up the draws

Heck out these details on the electrical
System

So you can produce up to 175 watts at what rpm
Most times at idle you will be some where under half of the wide open watts
So let's figure sitting at a stop light going to make a turn the most amps drawn
You have 35 for your headlight 3 for the tail light 38 for from t and rear turn signals 26 for the brake light assembly 5 for the plate light and 3 for dash lights that is 110 watts then throw I. Another 24 for the fuel pump my ecu drew 4 amps so now you are at 135 sitting stoped waiting to turn so you are drawing on your battery when slowing to turn or sitting at a stop
If you just turn the scoot on and idle 35 3 5 5 and 3 plus 24 and 4 so just staring the bike doing nothing you are drawing almost 80 amps so at best you are neutral no charge to the battery

Assuming you have a full dc system the onky time you will get your battery to recharge and not draw off the battery is at wot and that is if everything is working perfect and you have a full dc bike

An led brake light will help a bit the issue is headlights and then your turn signals you have to make sure the led flasher doesn't simulate the heavier load of staff bulbs t9 gain anything there

Even factory efi bikes like the zuma have a draw on the battery at lower rpms and when they have a weak battery you are left stranded

Assuming your rating is at 5000 rpm like I've seen for many 4 stroke stators
at idle you re putting out about 30 watts to get so you aren't running off the battery you need to be around 3000 rpm to hit 90 watts

Time to get the stator upgraded I think I have 3 weeks before everything arrives
