Hello everyone,

Was looking forward to my daily ride when all of a sudden my 2020 Vespa Primavera 50cc did not want to start.

It is only 1 week old with 60 odd miles on it. I used it during the day with no issues. A few hours later, it did not want to start. I tried 4-5 times, it was close but no cigar.

I have no carb, Iím thinking a vacuum leak? I will contact dealer ASAP. However, your insights and help are greatly appreciated!

Fun fact, a friend has the same Vespa, new as well and had to try 5 times for it to start one day.

Is this a common issue on such new models?

Thanks in advance!

Check the kill switch?

Hands off from the throttle
Just reminding that injected engine tolerates absolutely NO throttle when starting, so keep your hand away from throttle. If you don`t, it will wet your sparkplug and starting becomes impossible. Then you must wait a minute or two before trying again.

Since it is a brand new vespa, it cannot be too dramatic. Loose hose or battery lead could cause bad starting which gets worse if you try to give gas. Check, wait and start again.

All of my injected Piaggio engines totally tolerate throttle during starting, especially in cold weather or just after air filter re-oiling. Nothing wrong with opening throttle if the engine does not start without it. It just gives more gas which was always a method for easier starting (considering that carb choke is just a thing which adds some extra gas too)

The newer ones do NOT allow any throttle while starting. Older ones, yes. I'm not sure when the new regime came in - a couple of years ago perhaps? It might be as long ago as when the ABS/ASR became the norm, and might be related to that.

What happens if you open the throttle a bit during cranking??

Not sure if the 50cc's are like this, but my 300 won't crank if it's on the side stand.

It disengages the starter. And won't even try engaging starter if the throttle is open at all when you hit the starter button.

2008 MP3 500 does not do this
2013 BV 350 does
2020 Vespa Sei Giorni Does
