The first ride with my new Lectron was in southwest Missouri over the 4th of July weekend, and guess what? It was hot and humid the whole time. But that did not affect my bike in the slightest. I'm 340lbs, so I run the red spring on my 2-stroke because, well, I need all the power I can get. With the Lectron carb, I felt a substantial increase in low-end grunt, I have never been able to tractor like this.
