2024 Nightster RH975 issues

[adventurebob]

I recently bought a 2024 Nightster RH975,, and within the first 1,000 miles the engine light came on. The dealership updated the software for "historic codes," but recently the light returned, and the bike feels laggy and less responsive. Last night it wouldnt start with 1 click, and i've also noticed the right turn signal indicator blinks like crazy, while the blinkers never stay on fully during turns, forcing me to re-engage them. I'm concerned about these recurring issues and wonder if anyone else has experienced similar problems.

Prolly sensor or ECU issue, and the turn signal behavior makes me think there might be a wiring or grounding problem. The dealership to do a full diagnostic

I had a similar issue with my 2023 Nightster RH975. The engine light came on early, and the bike felt sluggish after a software update. My dealer said it was "historic codes" too. For the turn signal, check the ground connection on both front and rear bulbs, it helped fix mine. Ask the dealer to recheck the ECU update.
