I am trying to look for a Simonini 48mm 3p piston(12 pen)/cylinder/head, to repair my Simonini 48mm motor (first edition 3p).
Story: during a full cleanup i’ve sadly broken the unique segment. It was not easy to find a new one, but i got it. But not with the right surface traitment, and in finality: damaged definitively the piston/cylinder 🙁
So i’m hoping to get it running again.
I don’t know the damage to piston and cylinder, but did you think about resealing the cylinder? These type of kits are worth to make the costs and better yet go for a better finish with nicasil instead of mostly chrome. Over here in Holland we have for instance; http://www.powerseal.nl/
