I've searched and didnt find any info on this so here goes. I have a 2012 Road Glide Ultra. I traded a 2012 Road Glide Custome for this bike. They both have/had Idle Temp Management on them where at idle, temp exceeds the programmed limit, the rear cylinder injector shuts off and helps cool the engine by pumping air only. Cool system. On the Custom it worked fine. Comes in on the Ultra and the front cylinder starts spark knocking so bad I can here it over the tunes ! People in traffic stare ! Really dont care about the stares, just the engine. I specialize in fuel injection/electronic engine controls on cages and have for years. Spark knock of this magnitude would burn cylinders down in most car engines. My dealer tells me its normal because its so hot. BULL I said. Its only 85 degrees outside, the Custom didn't do it. If anyone here has the same type issues with the new 103 and found some resolution, please let me know. I considered pulling off and allowing the front cylinder to melt...wonder if that would be normal....
