I have a K6 1000 with no power and no error message!!
When is start it up, it sounds like a bike running on only 2 or 3 cylinders and it don’t want to idle. As soon as the engine is warmer then 60\\\´C there is no problem.
I took it to my local dealer. He told me it’s a sensor on my air box. As soon as you unplug the sensor the bike idles okay, but during a cold start back to the 2 or 3 cylinders sound. When the engine is warm - No problem. When you plug the sensor back it simply dies!! Since the sensor was unplugged I receive a FI error!
