Hello Biddy..you should sell that tv to fund the other one..i know a man whod take it off your hands for small money...ha ha ..by the way the tv panels were carried over to the early li series 1 , my frame breather had a pair..
Yes ,vents were to aid cooling as were the vents at the rear of the frame.Carried over from the ld design i imagine.
I memory serves ,later models (non frame breather)had a different design flywheel side footboard with a scoop supposedly to draw air from inside the panel work!
