How a Vespa Engine Works

This is not complete. I forgot to mention how the clutch works or talk about the drive gears that link the crankshaft to the layshaft.

[@AnggieHarygustia]

Simple yet nice tutorial in how vespa engine works..

[@marshabonforte6963]

This was actually really clear and concise.

[@wraitheful]

Yes, awesome video man. It helps for those of us trying to know our rides. Thanks for posting it.

[@iowancamera]

This is the first time I've ever worked one one. I've worked on cars I've owned for the past several years. So in terms of complexity, this is about as simple as engines get.

[@mammainger]

Hi there dude! Thanx for your video. You have a very relaxed pedagogical skill indeed. I am just about to change the gear spindel (cross) on my Vespa here in Sweden and it's good to see how it will look before I am there my self. Thanx for sharing! J/Sweden

Vespa superb engine .Simple, strong and super reliable.Nice video !!

[@maskedavenger2578]

The Vespas were more reliable than the Lambrettas but still paraffin burning smoky crocks & nowhere near as reliable as a 4 Stoke Honda Cub .

[@skoot2u]

@@maskedavenger2578 Vespas and Lambrettas are both very reliable if they are left alone and used as intended .Lambrettas tend to be tuned more than Vespas to get extra performance and that's when reliability becomes more of an issue . There is no point comparing a two stroke with a four stroke , totally different beasts. I've owned bikes and scooters and been happy with both.Compare a Lambretta SX200 or TV 175 with the equivalent bike of it's day eg. Triumpph Tiger Cub , BSA Bantam etc. and they are easily more reliable and can out accelerate either , I know ,I've had both.

[@iowancamera]

Haha, no worries. I don't care about the ratings. I'm simply uploading this stuff for a blog.

[@summerman2]

great video. Makes it look simple. Very encouraging.

[@yorchil]

good mariachi back ground music :) thks for explain that!

[@karthikneo12]

Thank you so much , but as you mentioned there could be many factors, only when you visually inspect will you arrive at the problem !!

[@bredlo]

Great demonstration - thanks for posting it!

[@iowancamera]

@sambking This is a 1964 VNB engine, meaning a 4 speed 125cc engine that was used in Allstate scooters and Vespa 125 scooters. It looks nothing like your LX150 engine which is 4 stroke and uses a variator CVT transmission. Two completely different animals, but both are great scooters when they are running right. My wife has a 2006 LX150.

[@bhektiari7772]

My vnb4 3 speed have noise sound from gearbox..maybe you have some tips for me...

[@akjjb]

Great vid mate! Do some more if u can, I'm owning a px also and I'm very interested in how it works... 5 stars

[@stenic2]

Very well done !

[@gotdemagot]

Thanks for the explanation.

[@Jaiv74]

Nice Video!! Thanks for explaining!

[@iowancamera]

@miguelmpn This is a 1964 VNB engine. 4 speed, 125cc from the factory.

[@Mattyew]

I LOVE VESPAS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@ivanpadrenostro6018]

best engine italians ever made

[@Tolis-py2dc]

what about the lampredi engine then?

[@damiandobson2905]

i built one of them today :)

[@stefox2003]

Always wondered! Thanks!

[@Coolsince82]

sooo cool dude thenks

[@ancientoneuk]

Large frame, basically nothing has changed from the early 59 152L2 era large frames to the current LML and P ranges save panel mountings and steering tubes and the brake pedal, the older rounder tailed frames survived in the Bajaj Chetak until the early 2000's and very easy to convert to Vespa standard

[@fordsvt23]

Can u show how you were able to pull out motor from bike and how you go about pulling engine apart please whenever u can

[@sodasouth8032]

[@ElCincoSiete]

Whats up with the Jenni Rivera Music on the background? Lol 👍

[@fajrioggio]

wow thanks this video very helful but can you explain about Vespa Special engine?,im restored my Vespa Special 100cc 1978 but im still not undestrand about vespa special engine -greets from indonesia-

[@fairyheli2]

the engine, from a vespa

[@iowancamera]

@karthikneo12 The humming noise? Could due to vibration from the crankshaft being out of true? Or 100 other things. Did you measure and shim the gear stack so there wasn't any play in the cases? It could be clutch noise. There are too many things to make a good guess without being there in person to hear and feel the bike running. To make the brakes seat in better, scuff the drum with 150 grit sand paper or something. It should grab better after that.

[@internetscooter]

great video - i tried to rate it 5 star but hit the wrong spot and it won't let me undo the rating :( I am very very sorry. Anyone watching this video please take time to rate it so that my mistake gets overridden.

[@jkllfdsa]

Going to Americavespa in Richmond, VA this coming wknd?

[@rohai99]

Please help, I have a broken transmission cable, replaced it, but I don't know how to shift the transmission to neutral in order to sync the gear selector, and transmission prior to tightening the cable.

[@MiguelBricaBrac]

Crank up that radio, paisano!

[@muhammadbizmrthq6807]

thanks

[@karthikneo12]

Hi, thanks for the video!! can you please help me with the following. what should be the air screw setting on the vespa 150 ?? why is their a humming noise on my vespa after rebuilding the engine ??? The rear brake is not sharp, i changed the brake shoes and the brake drum / just installed them with out sanding the drum or the shoes.

[@charlescrisp2814]

Hi there.My friend and i are rebuilding his vespa engine and we would like to know what size the ball bearing size on the crank shaft is i would appreciate if you could let me know.Many thanks great video

[@215alessio]

I hope you completed that engine. :) Is it on your vespa now? grts and thanks

[@ovais909]

What happens when you apply the rear brakes on the vespa? Do all the part stop moving? which I think is very unlikely could someone explain

[@matycee]

I kept thinking you were gonna gun it....

[@cczerwionka1]

I have a 1967 Cherry Red Vespa that I am trying to get going. I see your name is "Iowancamera" I live in Iowa City, Iowa. Do you think I could pay you to teach me some things about how to fix my scooter on my own? I found this video very helpful.

[@CarstenLorenzen12V]

Very good video, i'm new to Vespas so i'm wondering: Is this a small or largeframe engine?

[@helike13]
