Will too long of an "idle" warm-up make these evos run rough? Kinda like not enough of a warm-up? Only thing I can figure on a bike that runs like a dream all the time. Past couple morning it's been chilly, so I idle her for a good 15 minutes while I get ready for work. Even so, I'm 4 miles down the road and she's coughing and bucking and refuses to go past 35-40. But, like always, another mile or two down the road and she's running like she always does.....perfect. Gotta be more to it than just the rocker boxes being hot, because they were.
I warm mine until I feel warmth on the cylinder usually 3-5 minutes , then again a couple years back I put a Dales Killer Carb on my bike. Perhaps you need to clean the carb and AC.
I never warmed mine up that long except for winter maintenance starts. Once I got it started I put my gear on or strapped my stuff down, rode a couple of miles with the road and pushed the choke in all the way.
I can tell you that my Sportster 1200 always coughed due to a carb that wasn't re-jetted after a Hyper-Charger & Slip-On exhaust was put on. Some said it was what caused the "coughing" while some other said all carbed HDs do it.
It was more a nuisance than a performance issue for me.
Generally, I warm mine up for couple minutes and take it easy for the 2-3 miles. Lately, since we've got new renters next door and they keep us up at night screaming at each other, I point the back of the bike towards their house and let warm up longer before I leave for work at 5:30 am.
I had neighbors about 30 years ago that complained about any music you had on. We even had the landlord sneak over and listen as they banged on the wall at about 2.5 on the volume dial. Said he couldn't do anything if they complained.
I started just backing the shovel out of the garage and starting her and warming her up right there instead of pushing it down to the curb like I had always done in the past.
Three days of that and they pulled out the white flag. Guess those 4AM wake ups changed their music interests.
