Hi Oily, you mean hot, especially with the exhaust/silencer in such close proximity? Can't you fit a universal stainless silencer with similar dimensions, it is such a hassle to make up a silencer yourself. Behind that left front panel on mine is only a silencer and the exhaust gas is still very hot since the outlet is so close to the engine. Each time I start the engine, it melts the nylon shadow netting pulled over for protection against the elements if not removed in time.
