    Just got back from Branson. The temps were in the low to mid 70s & I thought my engine was going to jump out of the frame at the red light. I reckon it was going into heat management mode. I have Python slip-ons, K & N air cleaner & a Power Commander USB tuner. If its getting hot under those conditions it will not make it thru the summer. Would putting on a set of true duels help pull the heat away from the engine?

    I lost alot of the heat when I switched to Mobile One V-Twin. Also maybe an oil cooler for you? I have Kerker slipons, SE Air Cleaner, and a TFI. Mine is running pretty cool, but it hasn't gotten real hot yet, only about 90 so far.

    I just had Syn 3 put in all the holes. I guess I should have gone with Mobil 1.

    Are you sure you're fuel tuner is set up right? I'm amazed that the EITMS would activate on a nice day in the mid 70's. Like Lancer said, I've ridden in the 80's to 90 degrees and not had it activate.

    Switch to a good synthetic motor oil and check the settings on your fuel tuner.

    In my '99 Ultra, I have a roller chain conversion with Andrews 26N cams, Big Sucker a/c, V&H slip ons, TFI, HD oil cooler, and Mobil 1 and she runs very cool. The oil cooler and the synthetic oil really dropped the temps on my bike. Good luck.

    I have a 07 Ultra just got back form Palm Springs, CA Temp over 103 it’s just hot. But when I shout it down and restart it has a vapor lock condition. I have true duels and a K&N filter and I have built a divider switch for the O2 switches that makes the air fuel around 14.3 to 1. there are two power commanders one for off-road and the other for EPA witch one did you install?

    I have the USBIII installed, did'nt know of there being an on road or off road, so I really can't say. But I did'nt have this problem untill I put on the Python slip-ons instead of the SEs. I compared the 2 maps and there is a fair amount of difference in the 2. I may go back to the Screaming Eagle Map instead. I will be installing a V & H 2 - 1 system later on to see if that will help some. That will remove some of the piping near the back cylinder.
