I have to agree, if it does not have the cams and pistons, it's not really a Jota. But................... my local Laverda dealer back in the day, would take new 3CL's and add his own high compression pistons, Axtell camshafts, Jota exhaust and a flowed head. They were sold as a Jota and were actually faster than the factory ones. Now can we call them a Jota?
Also, did the factory ever make series II 180 motors with the Jota cams and pistons or is it just a standard bike with a Jota decal?
Here in the US we also had the Jota 1200 America which is not really a Jota either.
