I'm with starluckrc, there is more heat from the left side of my engine than the right. But nowhere near enough to "cook" my leg, mesh riding overpants (which I now wear regularly) or not. It's been in the 90's here in South Texas pretty regularly for the last week or two, and I've not had any concerns about my engine. It is a bit wierd to hear the gurgling as the coolant drains out of the overflow resevoir back into the radiator!
