Hi has anyone any information about MDP ? kits for Px200 My mate gave me one he got in a box of bits is all there piston looks like Gran Sport Polini ports similar to Polini but has bridged exhaust port any info would be a help. Good or bad??

Taffspeed told me they thought it was an MDP from the 80’s it is used but still in good nick

MDP? Honestly, I’ve never heard of such a kit. Is it brand new when you got it?
