Modern Vespa

Had to go into the city this afternoon to get the girls phone sorted so I thought I would take the Super because I knew it had the most fuel in it. Got to the phone shop and sort of got it sorted in Typical Vietnamese style.

On the way home and the fuel dies, no problems flick onto reserve all is good, good no the engine dies. Wheel off to the side kick her over all good of we go. Sit on the scoot and she dies again. Shit problem with fuel tap and reserve.

Ok first thing let's get it full of fuel and see what happens in normal position, so push to the fuel station usually always one pretty close due to so many scoots and limited distances. If you can't find a fuel station lots for sale on the side of the road but suspect quality.

Full of fuel, away we go. NO. Starts fine sit on the bike to go, it dies.

OK so what changes, when you sit on the scoot you bring the engine closer to the body, must be an electrical short. Remove cowl, reposition wiring away we go, BEAUTIFUL.

What are the odds of that happening exactly when you run out of fuel and switch to reserve.

Gotta love mechanical things.

Perhaps something has shifted and your fuel line is being pinched when you sit on it.

This has happened to me before. Everything was fine then all of a sudden, I'm pinched.

The first obvious place to check is right where the line comes out of the frame, before going into the air box.


That's my 2 cents.

Good Luck.

All good now. Relocatiing the wiring did the trick. Will have to check insulation and routing over the weekend. Suspect after start sit on scooter, suspension compresses and moves the wiring closer to the body. It was quitting as soon as I sat on the scoot, like instantaneously.

Cheers

If it's that quick it's probably shorting out somewhere.

pete, i guess its time to put a new wiring for the super i just finished rewiring one of my sprint as i get tired fixing nor buying another ready to use vespa wiring and my own creation is way much better (with a better wires of course ) i believe u can make ur own wires too pete

and about the fuel seller in the side of road guess its the same as in my place but i would never ever bought any fuel frome them and i believe u should do the same too as we never know what would they put inside that fuel.. normaly i just push the bike to the nearest gas station if i ever run out fuel

good luck with the wiring and cheer mate
