I've been watching this thread to see if anyone had come up with an answer. My '23 BSBL also likes to "surge" or sometimes feels like it is "falling flat on it's face" when pulling out into traffic before the engine is fully warm. It has done it at a traffic light a block away from my office...
Finally got around to ordering and installing the Retro Hockey Sticks stripe kit from Underground Graphics.
Absolutely fantastic product. Great quality 3M vinyl and easy to install after watching the video on YouTube. I went with the Matt Black and Badlands Orange on my Carbonized Gray Badlands.
