You're still running the 'base' map in the comp ECU. It's still a lean map. Lean = hot. Seriously, get the GYTR tuner already. You're obviously a tinkerer, and this is one tool that you can play around with to greatly change the personality of your bike's motor/power delivery. You're willing to spend the time and money etc to put YZF cams in your bike, yet you seem unwilling to simply tune your FI... why? Would you also refuse to rejet a carb'ed bike?? I don't get it... I have the tuner. I'm doing things in steps so that I can see the effect and we can LEARN from the process. First step was the rad cap. Then was adjusting the idle mixture. Now I'll play around with maps. FWIW, this thread isn't about overheating.
