Cheers ian,so for the mb piston would I need a rebore and need head skimmed to match?cheers maxi

Yeah, but the honda 205 conversion either needed the barrel topping and tailing or a 110mm rod using.
If the barrel hasn't been shortened you could use any lambretta piston as long as it fits and you check the port timings.
