air cooled engines?

Hi,
As i said above this may be a totally stupid question, but with an air cooled engine -



if you sit stationary for long periods of time with the engine running then the engine will gradually just get hotter and hotter as no air is passing by the engine - is this correct?



Will you get more heat given off, as in will you feel more heat coming from the engine as you sit on bike with an air cooled engine vs water cooled?



Please help.

Thanks!



I didn't find the right solution from the Internet.
