eBay
Brand new and direct from the remaining stock of the former Franco Morini factory in Italy we have this New Old Stock Italjet Formula 125 engine. The scooters these engines were fitted in (Italjet Formula 125) were very fast and expensive and I believe were the only twin cylinder auto scooters produced at the time and may be even to this day!
Should you be an auto engine fan and fancy building a Lambretta Auto or you have a Scomadi that you want to turn in to something special then surely one of these engines would offer the solution,and you could have a Lambretta with twin pipes!
The engine comes complete with carb and coils so the only things you should need to run this in a bike is a rear wheel ( quite often turn up on ebay) and a pair of exhaust pipes which you would more than likely need to have custom made to suit the fitments of your bike.
I have a couple of these engines available. The price is not negociable! these engines are worth more in parts than I am asking!
The engine for sale is currently in France and it can be collected from there or it can be collected from either County Durham, Oxford or possibly Cornwall subject to prior arrangement, or I could possibly deliver it on my next trip to the UK around the 2nd week of March but please email me if you need any info on this.
The engine is as stated brand new from the factory but is new old stock so obviously I can give you any warranty on this item. 
 Payment. To secure this engine I would require a deposit of £100 via paypal and the remainder cash on collection/delivery.
Any questions please send me a message!
