Looking for full rounded counterweights crankshaft vespa's ciao

[piontekTopic starterBerichten: 69]

Hi vespa folks
it’s been quite a long time I haven’t been here, but passion still in the blood 🙂
I am looking for racing crankshaft, with fully rounded counterweights, second hand or new.
Standard size of conrod and stroke 43mm , 12mm pin, (70 mm) counterweights .
Thanks a lot .

Its a 44mm stroke one, more air to suck in, race 😛

But now you need a 0,5-0,7mm thicker bottum cilinder gasket to get the ports strait again and that the piston dont hit the cilinderhead.

TICKLING BARN

Indeed a long time ago Piontek. Nice to see the passion is still there. The problem with the AMT 210 and 212 crankshaft is the cheeks are wider then 70mm. You need an AMT 206 or 208. Also isn’t it easier to get one of the racecranks in Italy instead of looking for it here in Holland.

Hi Martino! My friend how you doing?
Thanks for your advice, but it seems difficult to find it also in italy, and I remembered you guys! This great community.
I realized my profile is brand new,so I will update it in while.
Thaks a lot also to you Crullie 😉 but yep…I need it standard, at least could be 44 stroke, but standard counterweights.

I’ll wait if someone come up with something.
Greatz to everyone!
