Whow!

How did you Measure these things? The Cylinder looks exactly like the original!

But with a nicest exhaust port , I did everything with a digital caliper.

That's impressive stuff.

 

Please don't get me wrong, but I don't think it should read "Polini" on YOUR inlet manifold. From what I hear Polini can be touchy about thing like that. Could you please change this?

An other Point of view:

That is a perfect pattern for every chinese manufactor to copy the polini-evo cylinder...

Perhaps you should design a few bad details in the cylinder - an 82% wide exhaustport for example

From what I've seen in China they need precious little help for reverse engineering.

You're right Polini wouldn't be happy to find fake files on the network for product that are still on production.

 

As for the Chinese I don't know if this kind of file would really help them, they usually prefer to rebuilt a model from the beginning.

 

I'm going to resctrict the sharing to here with a google doc link for the Vespa stuffs.

nice work
