Vincent has it done on his Ciao. But he had to fusing his frame. He has a special or perso on this site with pictures.

Here’s the special btw. [url]http://vespa-ciao.nl/forums.php?m=posts&q=10382[/url]

bedankt man, en daarna ineens engels, is hij nou engels/nederlands (srry voor off-topic.)

4-spaaks velg met zo’n kleurtje ziet er btw best gaaf uit (moet die nog wel ff wat beter gespuit worden)

Hi piet, out the top of my head; the gear ratio’s should be around 1:16,5 for first gear and 1:11(1:9,5) for second gear. But this is also simply to find when turning the wheel around and count how many times your clutch will go round. Keep in mind that these ratio’s don’t do any good when comparing to the conventional poulie system. Because of the different diameters in clutch and forpoulie.
It also looks like you’ve got the whole complete system wich is very rare to find.
Only thing to worry about is the crank. It looks like it has the timigs for a “snorkruk”

i posted a comment on the 2gear project.. i was wondering why Vincent suddenly stopped 😛

It’s amazing how much rare parts are mounted on his ciao

-polini 41 lc complete
-the radiator
-2Gear
-Kickstarter
-rear brake with foot 😀

hope your 2Spead will work great, one day 😉

I thought Vincent was using this modified clutch as pouly simply because he had not the original crank an pouly.
I also thought about using this 2 gear crank in an membran block or to press this axel in another crank with better timings.

And yes somewhere in his perso(vincent) is a movie at wich you clearly can hear the ratio is to long for second gear.

I have bougth the 2speed set from vincent some year ago, and by this set came also a couple of orginal poeli,s and a orginal crank(with brom timing if I remember it right)
But he was riding with a normal vespa crank becourse he had modified a back poeli from the 2speed by forcing in a inerpart of normal clutch from vespa.
(A bit difficult to say in englisch:D)
And that he had no speed in gear 2 lays in the fact that he had not enough power in his engine, I will bett that my 43mm euro block will take that second gear easy

EDIT
Here some pics of the modified clutch/poeli


For montage you need a (vleugelmoer) and than welt that to the poeli.
And that works fine where vincents words.

And my crank is also a snor crank I quess?

But special thing about this crank was that it is a kick crank
(at least vincent was saying that it was very rare)
