Yes, ran separate hose from the tank which is sitting on a bench above the bike - most of the fairing is off so I removed the tank to access the coils etc - there is ample fuel to the carbs and I'm thinking the inner components will need cleaning as Tuckerbag suggests. Will take the carbs off and go through the process.
