Just a thought...
Are you sure that the lower chain guide is in the right possition and that it's not turned upside down?
If you do that, the chain might seems too short.

It shouldn't fill up that fast...
Have you changed the oil, if so you might have overfilled it and check the oil level.
The oil in the tube gets sucked into the carb when it's overfilled and that is probably the reason why the engine stops...

I would drill out the Oil drain plug on the other side of the engine and mount the sensor there.
Easy to replace with a new one if something fails...

I would check the valve clearance.

The colors of the wires on a normal GY6 scooter should be:
Brown fed with 12V AC when the engine is running and the switch on the right side is the center position. I think that the brown cable in your picture is for dashboard and rear lights.
White is fed with 12V AC when low beam is on.
Blue is fed with +12 V when high beam is on.
Green is ground.

That's a good port jobb!
Two minor things doh:
At the top of the intake port, I would smoothen out the edges just before the valve guide. Just so that there is no disturbance in the airflow.
And the port is a bit too polished for my liking...
When the port is too polished the air has a tendancy to start bouncing off the walls and that causes turbulance.
You want the air to flow smoothly through the port without any turbulance. I would use a 240 sandpaper and that gives a smooth enough surface and not too polished either.

I cheated and found a local dealer who took my old bike in trade on a high compression Italian 250 designed from the ground up as a fuel injected bike. Sometimes that will cost less than tinkering with converting a low compression bike to EFI. Most bikes designed for fuel injection have a stator that puts out 300 to 500 watts which is needed to run the injection pump and consistently fire the fuel injector. Plus it was guaranteed to work right the first time I rode it and had the backing of a dealer network of factory trained mechanics here in the US and most of the world. The current draw isn't that much as one could believe on the EFI kit. I have a stock stator and I haven't had any problems. I did change all light bulbs in dashboard to LED and the rear/brake light to LED also... |

I'm amazed you guys have so low octane... The lowest octane we have here in Sweden is  ! A long time ago we had  octane... |

The install isn't difficult, just follow the manual. I changed a few light bulbs to LED and I haven't had any problems at all with the stator not being able to produce enough power... Here's som pictures from my install: scooterdoctors.egetforum.se/guide-inkoppling-av-ecotrons-efi-insprutn-till-gy6-motorer-t1470.htmlSorry, but the text is in Swedish..., (just run it through google translate and you'll get most of it)Some of the wires on the harness I would like to be a little longer. I extended the cables to the battery, the control lamp, performance switch, ignition coil and CKP cable. If you place an order I would recomend that you order an extra holder for the lambda sensor. It might come in handy if you replace/change the exhaust after a while... |

Matt at Ecotrons will give you advice.
Just send him an email and he'll help you.
The support from Ecotrons is outstanding!
The 34mm throttle body has idle control via the ECU and I think that can be a great advantage
I have that system on my 150cc GY6 and I love it!

I always start the alignment of the cam by verifying that the piston is at TDC.
I then install and align the holes on the cam with the cylinder head and finish it off by checking the valve clearance.
