Thanks so much for sharing this information! This is what the internet should be.

The Piaggio moped engine is such a simple thing, but I like it very much when things are simple and tough. Nice tutorial about the rebuild. I have done these work many times and so I can say this is a fine guide for beginners.

Great video! This will be my go-to video if I ever need to pull the engine apart. Thanks for taking the time to show everything.

I am buying a broken vespa from a friend for an emergency vehicle and i hope this helps me rebuild the engine!!! You are amazing!

Hi Carsten, thank you very much for sharing your calm, essential and very informative video. It helped me a lot to bring an old Ciao back on the street. Kind regards Chris

today i started with the revision of the engine because it had some strange vibration. did that often in the past but not for some years . stopped half way and needed some help and advice so turned to you tube : your video is of great help ; tomorrow i am going to fix the problem!

Thanks for that awesome how to! This will help a a lot, because right now Im overhauling a bravo engine. Subscribed to your channel! Greetings from Germany, fellow neighbor!

Thank you for excellent presentation! I have learned a lot new things about ciao engine.

Thanks for showing how to do this. It helps me out a lot !

Dear friend, it's very interesting to watch this video. Very useful to understand the moped engine mechanism. Thanks for sharing and taking so much of pain to make this video 👌

Good work. It looks like you've done this many times before. I like your solid surface counter-top. A soda-blaster would make those casings look almost like new, and perhaps some Evaporust or electrolysis for rust.

im rebulding a piaggio bravo and this is gonna help me a lot, tanks

Very nice video ! This engine is use in my piaggio boxer too. ( sorry for mistakes, i am from Slovakia )

Great tips this guy knows the correct way to do it make sure to Pay attention!!

Great video!, Thanks for posting in English...I appreciate it👍

Respect for your work man

Sehr gutes Video! Danke Gruss von Heinz aus der Schweiz.

great video.thanks for the time and effort.central california.

You do an excellent job on theese Videos - keep on - Thank you!!

nice video thanx ; my motor parts did not want to loosen but then i had not heated them!

Tolles Video, bist ein Ehrenmann!

Great Video Carsten

Really thank you sir ,you had my total respect👌

Super video will use it soon to restore my engine.

also, a good tip for assembling bearings: after you heat the bearings, get a can of keyboard cleaner/compressed air can and turn it upsidedown and spray to quickly cool the crank shafts before dropping on the bearing. it's quicker and easier than putting the whole crank in the freezer.

Excellent video, Thank you.

Ziemlich gut erklaert gutes video

The professional job thank you very much

The best video available for the Vespa engine. Could You do more video’s of the clutch etc well so far thx

Excellent video! I've got a 1996 Kinetic TFR (Luna) which was made in India using a copy of the Ciao engine but lacks the variator. One of the crankcase bearings failed in my engine. I took it apart and replaced the bearings. After the bearings had failed, I was able to spin it with a drill but not start it. At this point it had 100 PSI of compression. Not that great but not bad. That gasket that goes between the two engine halves they sent me looked like it was cut from an aluminum Pepsi can and did not seal worth a damn and lost compression and sucked in air. After putting the engine back together the compression dropped to 90 PSI and would only run at WOT (lean). I then discovered gas/oil leaking from where the two engine halves go together. I made a paper gasket from the aluminum one I was sent. I put the engine back together but for some reason this time it would not start at all. It took it apart again and accidently broke one of the rings which trying to remove it. I should have replaced them anyway while I had the engine apart. I ordered new rings but got frustrated and quit on it. That was eight years ago. It may have been an unrelated issue (carburetor). I boxed the engine and parts up and pushed it into a storage building and it's sat there ever since. I just recently acquired a 1985 Tomos Silver Bullet. I'm putting a 70cc kit on it. I also have a 1999 Tomos TX-50 dirt bike which uses the A35 engine and transmission. Don't know if these were only sold for the US market. You've inspired me to get my Kinetic out and take another look at this thing. One reason I watched your video is the ring orientation. Seems like the go on a certain way. And that decompression valve! I'll check out your Cioa performance video. My Tomos seems to be restricted to 32 kph. I think because in the 1980s you could ride this if you didn't have a driver's licence. BTW. I live in Tennessee, United States. Interesting enough, the moped laws that were in place in my state years ago seem to be obsolete. I had to register my Silver Bullet as a motorcycle and there is no laws on increasing it's power as long as I don't go over the posted speed limit. I also have to have a standard driver's license (125ccs+ requires a motorcycle license).

complimenti per il video. ottimo :)

Thank you! It helped me alot!

Tak for den her mega gode film du har lavet her, den er virkelig guld værd👍🏻 har selv lige renoveret min egen ciao motor ved hjælp af denne film 👍🏻 plus man blev en del klogere på netop denne motor 👍🏻😎

Thanks! Really good video!

very good job, thanks a lot

tak for en god video skal til den helt store renovering på min ciao din video hjælper mig nok en del :D

mi ero addormentato a guardalo... continuo domani

i love what you doing man, i started doing this rebuild i few months now, the only problem that, i am facing is i cant fint flywheel removal tool :'( ! i dont like to use hammer ! thanks for the videos

Thank you bro good man.

lækker video, kæmpe hjælp, da jeg skal i gang med 2x renovation af vespa ciao motore

You are the best

Veldig god video, hilsen fra Norge

Hello Carsten I was wondering, do I need to tighten the small housing at the top of the crank house case at a specific moment, because when I tighten it, it’s almost impossible to turn around the crankshaft. Thank you for your informative videos!

Ganz locker das beste ciao motor video. R E S P E K T

You're English is better than Americans I know. I'll never understand why I couldn't learn another language this well. Even after 10 years in Germany I wasn't this fluent. Sigh.

bruh.. you did it better than an italian. great job.

Where do you find the Cylinder With the same size but made of aluminium?

thanks for the nice vid :)

Thanks for this video :)

Gutes Video und ordentlich erklärt, wäre aber schön wenn es dieses noch mit deutscher Sprache gäbe.

damn that's a small ass intake port, I didn't know they came that small. my Ciao seems to have poor ignition, the spark is weak and sometimes takes a lot of pedaling to start, especially when hot. I use NGK B7HS normally, it won't spark at all when using a surface gap spark plug without the little armature, I believe it's NGK BU8H type plug.

hallo just want to thank you for this great tutorial. 🗿

Do you have a video showing all the cables?

Hei Carsten, fantastisk fin video. Jeg er i gang med å renovere en Ciao jeg fikk av min bestefar før han gikk bort. Vil gjerne at den blir helt strøken, så derfor ønsker jeg å vite hva du renset motoren med? Et karr med en børste? Håper du har anledning til å svare, takk på forhånd!

5:35 = "keyway" on the shaft and washer/ bushing slots 38:00 = "key" goes into keyway slot and washer/ bushing slots

Thank you

Hej Carsten. Jeg har renoveret min motor nøjagtig som du har gjort ved denne. Men efter 1 km køre tur, så begyndte den og lugte brændt fra tændingen. Svinghjulet køre helt frit. Kan dog se at føde/lysspole har haft kontakt til svinghjul.

Vielen Dank damit kann man endlich mal auf Fehlersuche gehen. btw. Denglish vom feinsten :D "if there is a short" traumhaft ! mach weiter mit den Videos.

thanks for these video . i have same moto bike but the probleme can't start every morning gaz is ok .candle too .carburetor too. i don't know whats happen .can you help me

Dankeschön

I need that clip to fasten the cooling shield onto the top of the cilinder; do you happen to know where I can get one? Can't find them anywhere, thanks in advance!

Can someone shed some light for me even with timing set it doesn't matter because the bottom point doesn't even move to contact the top point

Rigtig go video den vil jeg bruge når jeg skal igang med min ciao. Ville dog gerne ha set hvordan du fik plumpen ud ?😊👍

Hej Carsten. Jeg er igang med et ligeledes projekt som du viser her i videoen, så tak for gode fif. Har du et tip til at fjerne begrænsningen på en snild måde? du nævner noget med at krumtaplejet på tændings siden ikke er helt identisk med det modsatte leje som jeg ikke lige fik fat i? :D

Best cleaner I've ever used on aluminum isAluminum bright It will make your aluminum cases look Brand New

Very nice video, Carsten. I am restoring a 1971 Ciao, stopped for years. Did you say 12 Nm to tight each head nut? Thanks for sharing, oscar.

Hello again MR Lorenzen. I am considering buying a new crankshaft. The bearing at the rod end is making a little noise when I am turning the rod. It feels smooth however. Which aftermarket crankshaft would you recommend?

Encontre una en argentina andaba rara le pusieron cdi y platinos juntos ahahahah buen dato. Adjunta circuito electrico de encendido

When I step on my kickstarter on my vespa bravo it stops/jumps, I have think it might be the swing wheel being broken, it does not feel like its connected correctly to the engine like yours is on this video. Do you have any advise to what might be wrong?

Thanks for the great video. Can I test spark with ignition plug connected (/I did but no spark, so is there some grounding issues or what ever?) or should I use just open ended wire as you did?

do the points constantly make contact with the crankshaft or does it only touch it to open the gap on the points?

Does the rubber seal on the crank shaft ever go bad and cause the engine to not start due to lack of suction on intake side. I have a piaggio clone engine " kenetic" and it's has good compression and spark. But will not start. Thank you for this great Video.

Hvilken størrelse kugleleje aftrækker bruger du? Jeg kan se, at man kan få en 30-50 og 50-70. Tænker at 30-50 er den bedste?

link to the flywheel puller please?

God video. Mange gode fif til at splitte motoren af. Dog kunne jeg godt tænke mig du viste et godt tricks til at sætte krumtappen i motor blokken. Skal blokken varmes op så lejet der sidder fast på krumtappen smutter bedre i? eller er der et smart tricks. Men fedt du viser hvordan det laves. Tak. :-)

hey , great video i have same engine im trying to start it. installed new piston ,rings ,no leakage from head ,suction from carburator side works fine , spark is good as well as coils.....yet engine not firing up, a little misfires once or twice , hence fuel comes up , i thought maybe decompression valve might be leak but checked for leak test all good......but still engine not firing up... please help , let me know if i missed something, im stuck !!!!!!

hey nice video! ive watched it many times. Hope you can answer even though its such an old video. I was just wondering: are the crankshaft bearings lubricated from the fuel/oil mixture or did you put some bearing grease there?

When i did a rebuild on my Piaggio Ciao engine i didn't thought it was a difference between the two bearings so i just mounted them anyhow. And when i mounted my two engine blocks the crankshaft didn't turn around as smoothly as before. Do you think the cause can be the bearings that is on wrong positions? Is there anything else that can turn bad by having it like this?

Hello my friend, thank you for this great video. A question, what would cause a "weak" spark - one that can only jump 2-3mm, but not 6mm and definitely not 10mm? Same test as you have run, but the spark isn't jumping that distance. Thank you!

Hallo, Danke für das Video. Welche Lager benutzt Du? Einmal C3 und 1x C4?

I'm sad bought myself a top racing crankshaft but heard you say this one is not good. Do I need to buy a new one? What are the weak points on the shaft? Do I need to use another needlebearing where there piston is on? I have a original piaggio used needle bearing. Is this one better then the one on the top racing?

I have no spark on my bravo. Tried a new condensor, didnt work. So i am going to do the test of ignition parts, as you do in the video. Can i keep the cylinder on, while checking for spark? Just mounted a malossi gasket set on it, and don't want to ruin it. Thinking of taking the spark plug out, and letting some gasoline in, just in case...

Can you please give the threading specifications of the flywheel remover. It's difficult to get that part in my country. Thank you!

Thank you for making this! Very good guide. I like that you not only tell how-to-do, but also how-NOT-to-do! Because it will save people from making common mistakes. You also mentioned the torque of the top to be 12 Nm. Do you also know the Nm torque of other bolts? Like say the crankcase bolts, the clutch, the pulley-"disc" or whatever it's called etc.... Is there a Nm torque table for this moped?

Hej Carsten. rigtigt god video. kan du fortælle mig størrelsen på de afstands ringe under krumtapslejet, og hvor man kan købe dem henne ?

Hi.. in my piaggio vespa I had a problem with the ignition. Then one bike expert converted breaking point platina into CDI.. Now the problem is the bike only starts when the chock air is closed in the carburator. When it comes to normal position it stops. What will be the problem here. Please help.

My ignition coil has 0.9 ohm resistance. However, it only measures 0.3 volts running when measured at the H.T. input. Should I replace the ignition coil?

Got 3 and the have some tape on the corners 2 green 1 black

Great video! I have a problem with the flywheel grinding the cable for the condensator. What am i doing wrong?

kan original crankshaft fra 25-30 km/t ciao fra 93 holde til malossi/polini cylinder kit?... du nævner på et tidspunkt de originale dele er ret holdbare... men det var vist mest si og bravo...

Hello man, so I have a engine I pulled out of an Grillo. Its seems to have good compression and it has spark but when the previous owner said it wasn't turning on and it really isn't . I have checked fuel and spark . Could it be a timing issue ? The engine seems good shape. Also great video !

Great video! what measurments are there on the flywheel puller?

Could i put first the bearings in the engine then the crankshaft

Hi there! I take some measurements before I close the engine an i realized that at the smaller crankcase half, there is a kind of embedded spacer upon which the bearing sits on. Measuring the distance from spacer to the edge is 1cm and the bearing has a width of 1.1cm. This makes it by 1mm higher from the bottom of crankcase and not fully inside. Is this normal? It is a model engine around 70s

Is it possible to use the original ignition with the 60cc athena? When getting over 45khm it just bangs and lose the power. Stop the engine and start again like nothing. Any ideas?

Carsten Lorenzen....Hi. I need to have a confirmation: at about 41:45 you show how to check if electrical system works well. My question is: the external coil must be attached to the engine case with a bolt as it seems in the images? Many many thanks in advance for your answer. P.S.: this video is really great and very useful! Thumbs up!

Hej Carsten. Sikke en god gennemgang! Kan du huske hvor du har købt din “vaskebalje” henne? Jeg har ledt efter en af den størrelse noget tid, men har kun kunne finde de store kar. På forhånd tak

Dónde se puede conseguir platinos para la moto Piaggio mod.80

Hej Carsten. Jeg har en vespa si fra 1990. Den plejede at køre helt fint men en dag gad den ikke at starte. Det ser ud til at den ikke laver gnist. Tænfspolen virker men er ikke sikker på om platinen virker eller kondensateren. Tror at den ikke laver nok strøm.
