Modern Vespa

I've been having random starter issues. But most of the time I can just get it to turn on. I have it on a battery tender. New battery. Was working just fine, but the process got harder and longer. So I rather not mess anything up and see if anyone here can help me out.

Any thoughts or ideas would be greatly appreciated, thank you.

Here's the link to the video I made: https://youtu.be/LW1WSX1ftX4

PS. I have an 2006 Vespa LX 150 ie

Is it fuel injected? I did not think they hit the market till 2010 in the states.

I had a typo sorry. It's a 2006. Sorry about that

Battery is weak/dying. Charge it/replace it.

There's no need to wind the throttle grip each time you push the starter.

I have a new battery, charged. It's on a battery tender as we speak. Lately if I don't wind the throttle it wouldn't start. I don't know anything about this field, is why I'd rather ask the dumb questions.

Sounds like a battery issue to me aswell. Do you have a meter? What is the voltage, how old is the battery. Sometimes they can register good voltage after a charge but are dead. They cant give enough amps to crank properly. I dont think it is a starter issue because it is turning alright when it has the juice to it. I would check the battery first. Then check the wire that runs to the top of the starter, make sure it is tight and not corroded up. If it is not a battery problem or a wire connection problem we could try a new starter. I have a few kicking around I could send you out one and you could try that. They remove easily with two bolts, take about 5 min to change. But I think it is a battery issue, tell us more about the battery, if it is new what is the model of it? For example 12bs or something like that marked on it.

Having a hard time starting can be caused by bad gas, if you dont put alot of miles on it or your gas is 6 months old it could be gas or clogged carburetor. How's it run on the road last time you took it out?

Also I would add that the confusion on the model scoot you had was because it is marked 150 ie the IE is for fuel injected scooters. Your would be just a lx 150. Fyi
I have a 2009 S 150 in 2010 they made a S 150 IE having the fuel injection

It should just need a little tweak of the throttle once turning over. No pumping.

How many miles on it and is it due a valve check?

Each time you twist that throttle, it squirts quite a lot of gas straight into the engine. It soon gets flooded, which doesn't help your demonstrated poor battery issues.

You say the battery is new - why did you change it? Perhaps your regulator has failed, rather than the battery?

I will get readings on the battery today and update. Thank you all so much for the great questions and input. Thank you so much for generosity on the starter I'll check that out as well. I got a new battery just since the old one was sitting for a while. I would get it to turn on, but with issues. The new one worked just fine. I'll get the info on the battery as soon as I'm home. Thank you again.
