Hello,
Picked up this boy today, ZAPC24 with C241M engine. It has mono gear and from what I understand it’s a 2002 year model?
The grote carter is stamped 98, and klein carter is stamped 97, engine says C241M on it, as well as VIN plate. The VIN-plate also says “10R-01.4138” under engine.. I don’t think it’s the original engine fitted? Or perhaps Piaggio used old stock with parts when building?The carter says D11,5×7,5, and that would be a “brom” block? 45km/h?
In Sweden “brom”/45kmh was never sold, only as 25km/h, normally there is a restrictor in the inlet, this carter seem to be “unplugged”/no restrictor. There is a SHA 12/12 fitted on it.
Don’t know much about the exhaust except it’s rusty.1. Is this a “brom” carter?
2. Is there bromkruk/snorkruk even for C241M or is this only for older engines and new models have the same kruk?
3. Do all D11,5×7,5 carters have same timings, or is there “belgisch inlaat” and other varieties of inlets within this type of carter?
3. Is 12/12 a standard carb for this model jaar of Ciao?
4. Is this exhaust original or some sort standard-looking tuning exhaust you think?Don’t have any big plans for it, buying a new exhaust, City-power maybe? And just use it this summer..
Maybe this winter, split the engine and change bearings and perhaps tune the inlet..
Nice! This seems to be a “brom” carter. The newer engines also have the different crankshafts with “snor” and “brom” timings. the 12/10 carb would be the original “brom” carburetor, and the “belgische” carters are paired with the 12/12 carburetors, so no it is not original. The exhaust looks like an aftermarket exhaust which looks stock, but im not 100% sure about what exhausts came stock outside of the Netherlands, so it might just be the original one, replace it anyway. Get the Gianelli citypower, it’s by far the best choice 😛
This is how it looks on the inside.
It is a snor.(Sorry Dustin)
I am not entirely sure, but I believe that this is the last ciao model that was made.Ohh, it looks like there is potential for improvements in the carter..
The grote carter is manudactured 1998, but yes I’m pretty confident this is the last model..
It looks like there have been a steel bushing in my carter that someone have took out, the surface look honed.
Perhaps I can look inside the inlet without splitting the engine, finding out of someone have tuned it already or if it is the size of McDonalds straw.Oops, the intake looked the same as my brom carter and obviously bigger than my snor carter, so i assumed it was brom, excuse me 🙂
I’m looking at DR 43mm, according to JMPB this will not fit this carter? I thought 43mm would fit all carters, but 46mm needed to be reworked.
Is this the DR-EVO?

Yes it is…
I also think that it does not fit, but you can measure the outlet if it is 23.5 mm instead of 22 mm, then it is a limited carter.
There is also a steel ring in the inlet. you can’t pluck it out. Because the ring is poured into it.
You have to remove that ring in its entirety, because the pieces are loose.Thanks,
Funny, larger outlet = restricted/limited.
I think the steel ring/bushing already is plucked out, see picture 3.. The inlet is 11,5mm.
Thats what you think……. it lurks in the depth.
Hmm never seen one of thoose restrictors before..
Is it esy to pluck out? Do I have to cut it?
Perhaps there is an dutch instruction on the forums?
Here is a picture of the steel bush of a “snor” Carter. The inlet is 7.5mm wide.
type 990514
Your carter looks like an original “brom” carter.Yes, that steel busing is familiar! Thoose are common in Swedish standard carters..
I have measured by oulet/uitlaat and is measure ~22,3-22,5mm
I managed to take some photos from the inlaat aswell, it looks unplugged??
All of the ”98” carters i had were ”Belgische” carters.
And it looks like yours is too. you propably have the big inlet.I don’t know how it came on the market in your country.
The ring that is in a limited carter is hard to see. It’s in the back.
A ring was placed in the casting mold, and then the aluminum was poured into it. therefore, the ring cannot be removed. You have to mill it away. (I melted a carter and then that ring came floating up. Thats why I have a picture.)When I look at the pictures, I doubt whether this is a limited carter. Here, it is a taperd inlet and in your picture it seems to be straight.
