Agreed, run it out of the current petrol then fill with fresh. And add either BG44K or Chevron Techron Fuel System Cleaner Plus. Those 2 are the only additives worth trying, the others are snake oil. I can personally vouch for BG44K. Keep in mind that they are designed to be used for the duration of a full tank in an auto, so about 3 tanks worth in a bike (600 km or 8-10 hours).

Tech picked up a fault on the lamda sensor..just waiting to see if that cures it...kind of thought it was probably an A/F issue... hopefully it's a warranty job... I'm sure that's covered..
