Derno I used the blue combo since it produced more power all last year.Never had a overheating problem.But yes I agree our quads like to run rich.
I wasn't looking to much at just overheating as I was at running hotter in general. Just a theory of mine, but with the weak springs and such heat would cause earlier fatigue which in turn would cause head failures. That was where I was heading. I know you know what you are doing completely, but most of the people running around with the D&M kit don't truely understand the great tool they have been given and the need to at least get close to a good number.
