Hi all, finally back on a 2015 Speedmaster. Not being one to leave things alone for long, I've started the usual mods but have run into problems. This is my first EFI bike.
Today I:
Removed the O2 sensors, using a kit that came with resistor fitted connector blanking plugs.
Removed the AI system
Swapped the standard exhausts for short 19 inch turnouts.
There are no mods to the standard airbox
I started the bike and let it run for 20 minutes without touching the throttle as advised.
Went out for a ride. OK at first but the bike is stuttering a bit. As I rev up, it stutters and then seems to clear and run normally on til I hit the next gear and then repeats for each gear.
Is this a symptom of lean running. I haven't remapped yet as I was hoping not to until I can afford the airbox removal. Or is this a problem with either the AI or O2 removal. Thanks in advance for the help
