I went for a ride today - 100+ degrees. I got stuck at a stop light and my scooter really sounded bad. New bike, less than 1000 miles. Then I realized that the back cylinder had shut down at idle because of the heat. First time this has happened to me. Life is good!
( we had a guy post on here once he was gonna "sue H-D 'cause his bike wobbled all over the place."...tire pressure: 25 pounds)
enjoy the new ride, enjoy it more by knowing the whys and wherefores of what it is doing.

Yeah, I read the manual and was aware that the rear cylinder shuts down when it gets hot. Thing is, this was the 1st time it happened to me and it was a little disconcerning.
HaHa - Yeah, 1st time it happened to me I thought something was wrong too. Although there are plenty of critics on this forum I am a fan of the EITMS. Here in Florida it comes on all the time.
Here goes the argument. I installed Xieds on my '09 Ultra soon after I got it. That summer we had over 60 days of 100 + temps. And have only had the cylinder cut out a couple of times since then.. it really does work. It seems to richen the mixture just enough to keep the cylinder below the critical temp.
The cause is the Engine Idle Temperature Management System (EITMS). It's designed to do that. The manual explains how it works and under what conditions it shuts off the rear cylinder.
