Hello All,
Recently I have noticed sudden and inconsistent fuel mileage drops from tank to tank. I just pegged 27k running a PC3 USB with out FCE or ECU re-cal.
One week I can be averaging 32-35mpg mixed riding, then upon next fill up I can barely manage 25. I'm racking my brain as to what would cause this? Perhaps a faulty PC or brakes dragging from being dirty? Maybe just poor fuel quality? Perhaps out of spec valves? (Unlikely as the fuel drop would be consistent, I would think
I have plenty of power everywhere and I haven't noticed a change in performance. The only correlation I have started to notice is a problem with the cold start high idle. Sometimes the bike starts with the high idle as it should, other times it starts idling at less than 1k rpm and is prone to stall. Maybe I'm having a problem with the idle control valve holding a proper mixture?
Any insight from any of you would be greatly appreciated.
Thanks
