- this problem might be a worn variator-belt/rollers - the Vespa technology requires a variator-belt service every 10'000miles
- contrary to the belief that the carburetor causes such trouble it is a common issue with Vespa engines that people are not doing the replacement of the variator belt in due time...
no eBike stated, maker nor model, wow, must we work blind too.? sure in a text box blind.
no question stated, only some vague words.
you do know it's battery powered, right and if not kept charged it will not GO.
and if charged too little , range is less.
and all batteries have short lives, per this.
and the range will decrease as you drive further, to far.
the battery maker even has chart to learn this.
as you stress any battery like this , the total range reduces.
Just like your CELL phone same thing.
- you can do this by yourself only if you have good mechanical skills as you have to dismantle the whole dashboard/handlebar!
- better you ask your vespa-shop to do it on your next service...

No, you will have no problems at all. In fact if you ride in very wet conditions your oil will perform better than normal 2 stroke oil. But seriously though, unless you are getting the marine oil at a very good price, you could just as well use a regular good quality 2 stroke oil, it is a few cents cheaper on the normal market.

Hi, Unionjak if you have changed your engine size, compression ratio, fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve, and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water, etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. Your engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" you're not getting enough fuel.
1. Close to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide-open throttle is managed by the main jet and air jet.
6. A wide-open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, the engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark grey, the engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.
