My 08 FLHX has stalled on me in traffic 5 times on long rides so far.As I have cruise and all 5 times have lead a group on long highway journeys to different events,I have narrowed my problem down to this feature.Every time my bike has stalled in traffic after a highway trip useing cruise which enables the rear cylender shut down.In my opinion it realy blows when your new bike stalls because a cylinder shut down.Ten tears on my EVO and I cant ever recall it stalling in traffic.
Sounds like there is something more going on than rear cylinder heat management system. My rear cylinder cuts out when sitting in traffic but never stalls out.
