OK, its made in Italy, Was manufactured in March 2001. The guy bought it when he bought the scoot, just never installed. (He never really rode it, only put 3,000km on her in 10 years). Set has carbon fiber malossi reeds. Model # from the owners manual is 3111667. The cheapest I could find this online is $279. Selling a new, unused, in original packing, italian made, cast iron bore kit for nearly 1/2 price is NOT unreasonable. It's here if u want it. Was gonna use it when my stock top end gave up..... but at 20,000 kms, shes still running strong.
