While I experienced no issues on my Challenger with 6500 miles on it, and have had all the updates from Indian including the stage 1 mods (intake and mufflers), it was 93 degrees in Las Vegas and I decided to take a local ride around town to enjoy riding in a t-shirt and a brain bucket. I noticed the idle would arbitrarily drop 400 rpms while sitting at a stop light. It happened about 50% of the time and I would blip the throttle to keep the bike from stalling at the light. My guess is that it would have stalled once or twice which would be an annoyance. I checked traffic temperature and it was between 200-220F. While freeway temps remained at 182 once sustained with good airflow. It would be nice to get some feedback from the factory and from some mechanics out there.
