I have run 5 tanks through the Mayhem and running at 175 degrees. With the White Lightning 20% fuel I don't think I will need to lean it out much more. Runs very cool and has more speed then I can handle. I notice you also don't have to run the low end lean to get the quick acceleration. I have leaned it about half turn from the box setting on LSN and 3/4's on the HSN. Very fast.
I LIKE IT!!
