Yeah, Fatten it up,or make the fuel/air mixture 'richer'
More fuel can make the engine run a little cooler. It would require a laptop and a re-map, which I know only enuff about to be able to say those words....

When the time comes and I do some mods, I will need to re-map my bike, I will probly be headed to a dealer, or buying a laptop and learn how. (I hear it really isnt that hard to do, I just haven't gotten into that yet)
Edit: The stage 1 should have helped... maybe they turned blue before the stage 1?
