I finally screwed up my courage to hook up my GS-911 to my new to me second hand, well out of warranty, 2015 K1300S. There were a few known bulb failure faults. All faults cleared except an Exhaust Flap Servo Motor fault 10313. Do I play BMW mechanic, buy and install a new one? Or is there a better, cheaper (those things cost nearly $260.00) more elegant fix? The bike runs fine, but does pop on a 4th to 5th shift assist shift. it has an Akropovic exhaust. I’m wondering if the previous owner didn’t disconnect it?
