NO, what is stupid is continuing to harp on COMBUSTION temps when you've been told AND shown that you are wrong. The smoke is not produced in the combustion chamber! Once again, there are OTHER heat producing factors in the 4 stroke that make the EXHAUST components hotter than a 2 stroke, and mechanical factors that allow the smoke oil more time to heat inside the exhaust, and THAT is what makes them produce better smoke. Open your mind and stop clammering about inconsequencial details. You might just learn something if you'd drop the "know it all" attitude.
