As above have a very slight hesitation as I’m cruising along, absolutely no misfires etc when on full throttle so its lower down, I’ve only run one tank of fuel since I bought it through it but I know the previous owner didn’t ride it much and I don’t think he gave it any beans when he did ride it too! 2015 with 5500 miles, would it be worth replacing the spark plugs and try some injector additive?
I would first try a couple of tankfull of super unleaded which also includes some cleaning additives. Run the bike for some long high speed (legal!) runs. You are thinking of carbon build up. The spark plugs should give you a good indication. Is the bike modified to run rich? What rpm are you talking about I do not know how many engine on/off cycles the ECU needs to adjust the fueling after a reset; could your be still l?earning?
