I really enjoy watching your videos. Keep up the good work.

@harmos4308 2 года назад

Very nice and inspiring video. I where on youtube looking for information about ignition but ended up doing all modifications from your video on my Ciao with a 60cc Malossi kit. Using 186 degree duration. Of course I milled a hole in the side of the engine. It was possible to solder with a blow torch and zink. Had some problems with missfiring. That was solved by changeing the "no name" ignition coil to original blue one. The engine runns well and revs like crazy. Will try with stiffer clutch springs to improve low speed power. Thank you Carsten.

@SirCharles. 7 лет назад

this is excellent! I wish you made this video before I started building my Ciao engine. it would've saved me lots of research and second guessing when trying to translate the Netherland forums! I have the 43mm Malossi kit and the specs say to cut the crank 10mm open and 5mm close, so I did. my results are: inlet duration 186°, transfer 128°, exhaust 171°. the low end suffered quite a bit, although I am using single speed and decreased the rear pulley to 70mm. my top speed is about 43mph, I was hoping for 50 but it seems the techno circuit pipe isn't good for high end. very very good info in this video and it's laid out very clearly. even people with little mechanical knowledge would be able to follow this. and I'm glad it's in English. good job and keep it up! I'd like to see more moped videos from you.

@CarstenLorenzen12V 7 лет назад

Sir Charles thanks for the nice comment. You can regain a lot of the bottom end with clutch tuning. I like to lighten each shoe with two 8 mm holes and then use the black Malossi springs. The Techno Circuit isn't a good pipe, what I hear. Better take the Proma Circuit or even a Giannelli Original Power. 43 mph is allright for this setup, maybe you can gain a bit with a better exhaust, but don't expect 50 mph. That takes a larger gear ratio and will hurt the acceleration even more.

@SirCharles. 7 лет назад

Carsten Lorenzen thanks for your reply! yes I tried clutch tuning as well, but even with the weakest Malossi spring it doesn't rev fast enough to work properly. it just keeps slipping and takes very long to grab, acceleration is worse than the stock clutch springs. I don't know why it is so weak on the take off. I feel it must be timing or ignition because I've fixed the air leaks. could a weak spark cause bad acceleration? I saw your other video, so I will check my coils. but I've already replaced the points, condenser, and external/secondary coil so I think the primary internal coil is not so good. also it starts ok from cold, but after warm up if I stop and go in a store, 15 min later it becomes very hard to start. I have to hold wide open to try starting and I get some backfire too, I don't know if it's from exhaust or carb though.

@CarstenLorenzen12V 7 лет назад

Could be an ignition problem, my Piaggios start at the first engine rotation every time, hot and cold. I've never seen an internal coil fail, but have seen new and defective condensors and external coils. Only use the original blue Piaggio coil for the external one. I've only had problems with the remake ones. What jet and airfilter are you running?

@SirCharles. 7 лет назад

Carsten Lorenzen my Ciao is a completely rigid 1971 base model and it has a brown/tan coil. the jet is a 69, and I have no air filter, just a thin screen. I replaced the original coil because the wire broke off right at the base and there is no way to replace the wire on that type. so I am thinking there may be a timing problem because of the backfires when trying to start. but if it actually is blowing out of the carb instead of the exhaust, could that be because the crank was cut too much?

Thanks for the vid, I opened up the flow path in my Kinetic moped as you show, except I went with a 12mm carb opening, for some more strength in that tube, (looking for a bit more umph) after making a twin muffled expansion pipe (the pipe added 5 mph) and going with a 13;13 carb. I was curious if the porting would add anything to the low end- it did nothing there, but added some power to the goal of a 30 to 35 mph range. Mike

@davidbirkemose 5 лет назад

HI Carsten - thx for superb instruction videos. I do have a few questions though... 1. Is the 1993 ciao piaggio stock crankcase(with enlarged inled) able to fit any of the bigger cylinders offered on the market or limited by size?... says some of the bigger cylinders demands modification of cranckhouse as you mention, but will the "cylinder skirt" from ex BigDep fit? They look to big but are so temting hahaha. 2. When grinding the "plompe" away, how will I know wich carb to choose, many recoments the SHA13/13... 3.På dansk... Husk at motorblokken skal fræses, ved montering i en standard motorblok.... - når der skrives dette om de store cylindere over 43 millimeter, er det så nok at fjerne plomben? Hvis jeg nøjes med 43 millimeter cyl, kan jeg vist genbruge original topstykke korrekt? og kan man vinde lidt kompression ved at plane det lidt, det fik lidt ridser da det skulle afmonteres fra cyl. Det med at tilpasse skyllekanalerne til krankhus pakningstrik kan man jo først når man har cylinderen. Hvor nøjagtigt skal "inled" være, bare som på videoen eller bare nogenlunde som på videoen haha :-) hvad er forskellen egentlig på 10/10 12/12 el. SHA 13/13

@CarstenLorenzen12V 5 лет назад

Hej igen :-) 1. I standard blokken kan du montere alle 43 mm cylindre. Hele blokken skal fræses op hvis du vil have større på. Men en DR 43 mm gør det meget godt. 2. Det er diameteren, studsen kan max fræses til 13 mm, så tag en 13.13. 3. Du kan godt bruge standard topstykket, men plan det max 1 mm, ellers kommer dekompressions kanalen tæt på forbrændings kammeret. Det er i småtings afdelingen, hvis du tilpasser overgangen til skyllekanalerne. Under en håndfuld km/t. Men ved sådan en tuning er der gemt en lille smule, forskellige steder. Tager man dem alle med, er summen ofte tydelig at mærke :-)

@zomfgwtfbbq1 4 года назад

Hey Carsten. Sorry to bother. I slipped with my Dremel on the part that I wasn't supposed to grind in the rectangular intake in the crankcase side of the Ciao engine. Just made a small scratch but I can feel it with my nail. You reckon I can fill it with epoxy resin? According to the Malossi manual I found online it is very likely that my engine is screwed. Thoughts? Kind regards.

@CarstenLorenzen12V 4 года назад

Hi, fill it with a good liquid metal, i use JB Weld. I've repaired very bad intakes with it, with success so far.

Hejsa jeg er i gang med at lave en piaggio bravo der forhåbenligt kommer til at køre 50 60 men er lidt i tvivl med karburator tror du at 15 mm er for meget

@lassekristensen7664 6 лет назад

Hej Carsten, fantastiske videoer du har lagt op! Kan du anbefale nogle modifikationer, så jeg kan få min Ciao til at trækker mig op af bakkerne? Når vi er afsted i klubben er jeg altid sidste mand på toppen af de små bakker. Jeg behøves ikke meget mere topfart end 30-35. Jeg overvejer selv et hak i stemplet. Giver det mere at bore i indsugingshullet, samt større karburator/dyse? På forhånd tak.

@CarstenLorenzen12V 6 лет назад

Lasse Kristensen Hej, Ciaoen er begrænset med en plumbe eller kun 7 mm hul i studsen, dertil en krumtap med anden åbning. For at man kan gøre noget ved det, skal motoren åbnes. Studs og vinduet gøres større, karburatoren kan nemt slibes/bores til 10-12 mm. Luftfilter skal have nogle ekstra huller, eller skift til filteret fra 50 km/t modellen. Og så lige en inddysning. Hvis du ikke piller ved gearingen bliver den meget stærkere op ad bakker. En diskret tunudstødning hjælper også, Giannelli Original Power eller Sito Plus f.eks. Der er desværre ingen nem løsning på Ciao motoren. Hak i stemplet hjælper intet, den fødes via den i krumtappen integrerede drejeventil.

@gxlbiscuit 5 лет назад

Do boost ports lower fuel efficiency? I understand in making more power one would use more fuel but is there a penalty at more *regular* speeds.

@CarstenLorenzen12V 5 лет назад

I have no scientific measurements on this subject. What I've noticed is that my tuned mopeds run nearly the same km/l as the slow ones. They run a longer gear ratio, and i can drive the same speed with only a little throttle open.

@acpck 7 лет назад

I just bought a 75cc Malossi kit for the same engine as yours. Do I need to change the crankshaft too? I do need to mention that the stock crankshaft is in very good condition with no radial freeplay at all.

@CarstenLorenzen12V 7 лет назад

The original crankshaft is perfect, also for tuning. As long as there's no play and it runs straight. But you need to adapt the inlet timing like i did, or else you will not get full power. Beware that you need to mill the housing for the larger bore, all 43 mm kits fit on the stock engine. The larger 46-47 mm kits need to be enlarged for the cylinder skirts. The Malossi 75 cc is 46,5 mm.

@acpck 7 лет назад

Thanks for the reply! I've milled the housing a few days ago, thanks for the heads up. Regarding the crankshaft I don't have the courage to do what you've done. I am quite afraid that by doing this I will have to deal with strong vibrations at high RPM due to the fact that the crankshaft it's not balanced anymore. Some three experienced mechanics told me that I should change the crankshaft too, due to the increased power, otherwise it will brake in the first thousands miles. I do need to mention that apart from the big bore kit I also changed the following : - Delorto sha 13/13 carb - Malossi spor air intake filter - Giannelli Fire Sport exhaust

@CarstenLorenzen12V 7 лет назад

The original crank is one of the strongest on the market, together with the Mazzucchelli or maybe the Pinasco. And yes, you can get some vibrations. But you will experience this anyway because you change the piston from the original to the Malossi, that is part of the balancing calculation anyway. There are good racing crankshafts on the market, Mazzucchelli and Pinasco have a model with larger inlet timing. I don't know if they have done anything to counter the changed weight. If you have an engine case with ~160 stock timing, you can probably go pretty fast too, i've never done an A-B test on the same engine, so i can't tell you how much difference it will make. The Giannelli Fire makes power in the upper RPM band, it would be good to have more inlet timing to match it.

@acpck 7 лет назад

What's the difference between anticipated and non-anticipated? Considering all that was mentioned above, I've decided on buying a new crankshaft, but the Pinasco one is almost a hole 100$ more expensive than Mazzucchelli. Pinasco: www.ebay.com.my/itm/131116637408?ul_noapp=true Mazzucchelli: www.ebay.com/itm/MAZZUCCHELLI-ALBERO-MOTORE-ANTICIPATO-PIAGGIO-CIAO-BRAVO-SI-SPINOTTO-10-5184-/282379166905?hash=item41bf1c24b9:g:d4cAAOSwTuJYtqB3&vxp=mtr Is Pinasco worth almost 100$ more?

@CarstenLorenzen12V 7 лет назад

Just go with the Mazzucchelli, the one called AMT 004 for the 10 mm wrist pin. I don't know if thats the 5148 as they call it on ebay. But Anticipato means earlier/longer/advanced i think, so that must be the one with longer inlet timing. I just checked the Mazzucchelli catalogue, the AMT 004 (racing version, 10 mm) is called "Anticipato". So it should be the right one. I've used the AMT 004 before, it's very nice and durable!

@CarstenLorenzen12V 2 года назад

Moin! Die Kurbelwellenbearbeitung bringt einiges, die anpassung der Überströmer bringt nur gering. Ich mache nur eine leichte anpassung, damit der Gasstrom keine scharfen Kanten trifft. Aufpassen beim ÜS fräsen, da ist nicht viel Material! Calibrata bringt viel Leistung obenrum, ist aber schwach untenrum und in der mitte, den würde ich nur mit Vario fahren. Bei Mono definitiv den Sito Plus, und der geht auch sehr gut über den gesamten Drehzahlbereich. Wenn du die Kurbelwelle nicht selben fräsen möchtest, nimm die Rennwellen von Mazzucchelli, die gibt es in 10 und 12 mm und passen perfekt für den DR in einem aufgemachtem original Gehäuse.

How is the Athena kit? I have been using the Malossi 43mm cylinder for a couple years now and it still runs fine, but is getting weaker and still bad low end power. So maybe a good time to try a different kit. I've been thinking maybe a DR or Polini, it has to be 43mm as I have no access to mill the case wider.

@CarstenLorenzen12V 4 года назад

It's fine, but in the expensive end. The DR is hard to ignore, one of the best performers and the cheapest. You should have ok bottom end with a malossi 43 mm. Unless you run an expansion pipe exhaust? I only recommend the original style exhausts for single speed setups, like the Giannelli Original Power or Sito Plus. Though, that might have something to do with my weight also. :-)

@@CarstenLorenzen12V maybe I'll try the DR next, I hear it has a lot of potential for porting too.

Thank you,my ignition is to weak, the only thing I have not replaced is the condenser.

I’ve got a question: Why are you adding 10° on minute 27:14.

@CarstenLorenzen12V 2 года назад

Hi, it's a overlap that has been determined by two stroke racing teams, to maximize inlet opening and driveability. High revving engines can have even more overlap.

I want to put turn signals on my ciao 2 coil 6v moped. I suppose I would need to put a battery and turn the thing into a 12v system. Is it doable?

@CarstenLorenzen12V 3 года назад

There are models that have this from stock, with and added coil that goes over each half of the ignition and light coil. I've never worked with this, as we have no blinker models here in denmark. Try to search the net, maybe it's easiest to get a complete set with miniature battery/capacitor and blinker relay.

I did the same as you did but now I have no compression. What should I do now?🤔 Malossi cylinder 43mm

@CarstenLorenzen12V 6 лет назад

No compression where? In the combustion chamber? You need to check for leaks, gaskets, piston rings, decompression valve etc.

@lucastuder4557 6 лет назад

Carsten Lorenzen How should I check these things. I have a new piston with new piston rings and a new gasket. But an old decompression valve. What else could it be?

Yes it has boostports too, but they are pretty well fed through the piston.

Hmm i think this is the only video that shows that the small ports need to be dremelled all the way. Everyone else just makes a small dent that I do not think makes any difference.

@CarstenLorenzen12V 4 дня назад

@@titusm9837 i rarely make them all the way. Depends on how well they are fed trough the piston. On the Athena kits, only the middle two are open trough the piston, so i made channels.

@titusm9837 4 дня назад

@@CarstenLorenzen12V in my case i have a polini 65. It seems that all the extra openings are used by the piston (also they made some sort of M that connects all the small ones together). Should i in this case port for this other openings? I have not seen anyone do this until your videos. It kind of makes sense because the piston has some extra compression i guess? Interesting that i have not seen any manufacturer recommending porting for this openings.

@@titusm9837 i like to make a little "pocket" as deep as the opening in the cylinder skirts. This gives a nice channel to feed the booster ports, without any sharp 90 degree corners.
