Super nice Fantic badged Minarelli V1LKS. That string of letters means this is a kick start, case-inducted reed-valve V1.

This is a later model engine with the large square head for better cooling. 

It also has the factory Ducati CDI!

You can't use a normal Polini kit on this but you can use a BRN or rip the stock cylinder. 

These things really scoot even stock with just a pipe. We use this exact style on our Tri-Ped Microcar and it rules!

Comes as shown. You'll need to supply your own kick start lever and cdi box. We used an a55 box on ours.
