The gas hole on my S50 is Tiny! It barely fits the gas pump nozzle, and has some green plastic insert that makes it even smaller.

How the heck do I fill this thing without overflowing?

It's very easy to do this with European fuel nozzles, but I can't say whether it's more difficult with American ones.

Here you can find a tutorial:
I'm not a fan of putting the gas cap under the helmet compartment (2:14 in video)! Better use paper towels or an old T-shirt (form into a sausage and stick under the edge of the helmet compartment) to prevent the gasoline from running down onto the engine / exhaust when overflowing.

There is a "easy fill gas funnel":

I don't know if there are any special rules for an S50. In general, when filling my scooters I put the nozzle in straight, all the way, and hold the handle for slow to medium speed delivery. Don't try to fill the tank all the way; stop when the pump stops. You may miss that last 1/10 of a gallon but it's less likely you'll over fill.

With experience you'll learn how much gas your tank holds and you'll know when to stop before it overflows.

Good luck & have fun!

Yeah, the Liberty 150 also has the green insert.

Even being very careful, I got 1/4 cup of bubble up/spillover during my first fill up.

On the Liberty, though, at least there's a drain hole/hose to divert the spillover to the ground.

If the scooterwest screw on funnel fit's I'd try it.
Quick full fill ups, no spillage (even with CA nozzles),
no monitoring fuel flow, just let her rip

No matter how many miles you put on this bike, you are going to spill a little bit of gas. The best recommendation is know your bike. On my GTV. When I fill up at about 1.2-1.4 gallons, I stop and pull the nozzle partially out, this allows me to gauge where I am at in filling. It is not perfect science, but with the Gas Cap holding up the pet carrier, I don't seem to ruin any of my items in it.

It's not a "scooterwest" funnel, it's invented and made by racefoxx:

https://www.racefoxx.com/Fuel-Funnel-for-all-Vespas

And yes… it fits almost every Vespa and Piaggio/Aprilia models (except Bevery, Piaggio1 snd Elettrica 😜)

No don't think do. You overfill into that.....then what are you going to do with that cup of gasoline?
Works in Calif only.

Bummer and surprised.

One of only 2 good things about CA gas stations, the other is self service/we get to pump our own overpriced corn laced gas.

I get a small amount of residual fuel that I wipe out with a paper towel and trash

Just put the nozzle in fully, fill it up, slowly until it stops and pull it out, slowly.

If you do both things slowly (!!!), you'll never spill a drip of gas.


If, on the other hand, you try to get a little bit more in, with the risk of spilling, I don't see any problem in putting the cap between the pet carrier and the Vespa.

IDK - ??maybe the Germans watch too much late-night infomercials??

(or maybe they, like California, have those goofy gas-pump handles with the bellows on them)

O.S.

BTW - I use the home gas can thing on my Liberty. Then I turn key on - check bars filled on fuel gauge , stop when all bars filled.
The Kymco has a larger fill neck - and a bar down there which is easy to see - so I can use a filling station if I want.

I saw them some 30 years ago. They were short-lived. I think someone made the pumps work essentially the same way, but without the rubber thingie. There is a small pipe inside the nozzle that sucks in the fumes.

My Vespa GT200 is by far the most difficult vehicle I've ever had to put gas in. I don't live in California. But the filler is an absolutely ridiculous design. To make it even worse, they put those molded in ribs inside the filler. The gas nozzle is a tight fit. It can be virtually impossible to fill it up without spilling gas everywhere. Even Robot did it. I carry a one quart Gatorade bottle and a small funnel with me. When I have the tank mostly full, I fill up the Gatorade bottle, then using the small funnel in the gas filler, I SLOWLY pour gas in until the tank is full all the way up to the top of the filler neck. My evap system has been disconnected and plugged. Even in the second video, using that funnel, he said "you're pretty much very close to the maximum amount of fuel you want to put in there" "pretty much very close" is not close enough for me. I want the tank completely full.

There simply is no easy way to fill up a Vespa tank that I know of. Some gas pumps are either on full blast or off, some you can gently squeeze the trigger and just let gas dribble till the tank is full. But don't count on finding one of those.

I have one and I live and ride in Maryland. Works here. It allows the auto-shutoff on the pump to work, so it doesn't overfill into the cup. I have had it splash a bit in there on occasion, but it spills less that it often does without it.

Enjoy it now. When internal combustion engines are no more we won't have these threads.

It'll be charger plugs, battery life and and what type of dielectric grease do you use.

Amsoil anyone?




So what type of dielectric grease do you use on your e-scooter?

What's not being discussed is the fact that you can overfill your Vespa, leak fuel everywhere and then on the drive home just take your hands off of the bars during deceleration and let the 'wobble' shake the excess petrol off.

Feast your eyes on these, as hawked by none other than Ryan F9 a few years ago.

https://www.amazon.com/gp/product/B010GNM7H4/

Are these worth the price? Absolutely not. They are disappointingly cheaply built.

But do these fix the problem when used with home jerrycans? Absolutely.

Well, no. Not absolutely. I should say, they OFTEN fix the problem. Usually.

I don't know why they leak around the cap threads. They shouldn't. But they do. And the fill sensor ignores the filled state about 15% of the time and keeps right on pumping, so you have to ride the OFF button 100% of the time.

Whatever. It beats having to lift the whole can up to the level of the gas cap. There should be a much cheaper version somewhere without the dumb shutoff sensor that doesn't always sense. I haven't found one, though.

Pretty sure Ryan F9 did not test these very carefully.

I use the funnel that Scooterwest recommends (pictured above) but I can't just "let it rip" without having a big spill.

You learn about how much gas you need to put in and let it rip to the point of getting close to that mark. When you pull back the collar of the pump, just watch as it fills. If it looks like it's going to splash out, it probably is going to.

I usually fill the Vespas at the 3rd bar before I switch out to the next, that's about a 1.1 gallons. When I get close to the gallon mark, I slow down and peak inside, then try to pump slow as possible.

I also keep a yellow towel from Costco (the cheap microfiber ones) and drape the funnel with it in case of an overfill, but since learning the approximate amount of fuel to fill and then just filling slowly towards the end, I havent had any more spills. Works every time.

I ride a BV250, with the fuel tank in the hump between my feet. Because it's low I can look down into the opening and watch the level rise as I run the gas in. Just hold the trigger with one hand and hold back the bellows thing with the first 2 fingers of the other hand. I do the same thing for my Miata. Once in a while I spill an ounce or two, but that's not a big deal.
