Glad to be here sorry to meet by begging for help but here it is.

I just got a CF Moto E-Charm. This is the 150cc fuel injected and water cooled unit. It is a 2009 model but I bought it new 6 months ago and it has the full warranty. This does not change the fact that I am having problems and the dealer can't reproduce it.

First a couple sentences about me. I am a master gilded Porsche and Audi tech with almost 20 years repairing them. I got out of the repair industry a few years ago and now work as an aerospace engineer. I am a capable diagnostician.

OK Now what is going on. I am convinced this is 2 different issues going on at the same time. After riding for longer times, 2 hours or so, the scooter will start light failing. You can feel it in the seat of your pants. Just slight hiccups mostly under acceleration but also while steady cruising but in a far lessor degree. Sooner or later it will just die and not restart for an hour or more. It may start but this will only run for moments or until you touch the throttle.

The other issue also happens after long riding. This is cut out during vibration. What I mean here is that if I cross R/R tracks or thick painted lines, anything that vibrates the chassis rather strongly, I will get cut out and many times full shut down. I have also had this happen, which I feel is related; If I have the scooter on the main stand (the one that raises the rear wheel) and I start the scooter, when I go to push the scooter off the stand at times it will die. This happens before the scooter hits the ground. It happens right when I start to push on the handle bars foreword to roll it off the stand. This can happen even when cold but is very bad after the other above mentioned problems start, after riding for a couple of hours.

I don't have a wiring diagram as of yet.

The dealer informed me of problems with vapor lock. While this sounds right for the first problem it does not relate to the second set of issues. I have looked the system over by removing the tray above the motor and have noticed a complete lack of a fuel return system for the excess fuel. This little thing would fix any vapor lock issue and I will be designing a fix for this. I need CF Moto to give me the static fuel pressure required for the system so I can maintain the correct pressure to the injector.

Any help or diagrams will be much appreciated.
