Yep that bit is true
They had problems with the carby sucking water and problems with acess to the dizzy for timing and points replacement.
Also I think there was something about gearbox linkaging.
Photos of the prototype have been posted on here and on other websites.

I have heard both stories,
The gearbox issue I have heard is that they had no idler gear in the orange boxes which meant they had 2 large transfir gears, the rotational mass of which was too high for the baulk rings to cope with. Adding the third idler gear reduced the rotational mass....
The gearbox issue sounds more plausible as a reason to make such a major change, I am sure they could have sorted out the carb icing issue if that was the only problem.
However I think the truth is a bit more involved... From my experience a change like that would only have been made after a lot of consideration of all the affected factors, including, as mentioned, exhaust route, dizzy access, carb clearance, gearbox etc. and also from experience and lessons learnt from the first orange boxes (sometimes refered to as Atribute prototypes these days).
