An important update for all K1300 models is available at your dealer suggest you ask for it at your next trip to him.
How I learn about it ? well easy. Went to complain for some stallings occurred with 3rd and 4th gear in traffic. Asking if I should change fuel station or add some cleaner to the tank.
Mechanic suggested before anything else connecting bike to pc went ahead only to see that no fault codes related to fuel or electric systems were noted, in fact no fault codes at all were registrated. Then my good mechanic started to look at fuel quality and tested battery. Then a msg appeared to ISRA PC program informing about the update available. Did it and 20 min later bike was transformed to a rocket with a perfect idle no stallings and a much smoother throttle opening . At high revs engine is now smoother and appears to be able to deliver more.
