A quick but urgent and very original question. In the middle of Turkey right now with some bike issues. "Of course" didn't correctly mark which spark plug connector is which and can't identify them right now. Plus limited internet access.... in case somebody comes to the rescue it will be much appreciated... not dure what hapoens if you exchange thmm and sure this has been covered before ; but search in this conditions is tremendously difficult and slow.... when you get it to work at all. That said, I'm having abnirmallly high fuel consumption, like 6l/100km or 5,5 if i'm careful... and power doesn't seem to be there neither... Edit, managed to complete the search thanks to a nice turkish dude with a decent internet connection. Any comments are appreciated anyway.
