Ive been relying on my temp gauge because it helps me indicate if i will 4 stroke when i open the thottle all the way. Less than 320° i will 4 stroke but over 320° its usually fine however 320° is not my usual operating temp. Ill warm her up nice and hot before riding and blast off but as i ride at slower speeds in the duratation of my ride the temp goes down and i 4 stroke.
