Hi Simon
I would send your bike to Slipstream. There guys used to do all the CB1100R’s back in the day and what they dont know isnt worth knowing. I appreciate you are a distance away and the bike is off the road now, but its probably worth you sending it down especially as they will even tune it for you. They look after my 1100R.
