Can timing go awry with EFI tuning or does it tend to be stable? I guess anything can break down.
My CVO 110 Springer does this occasionally
I have always assumed it was a function of a "lag' in the ACR release system
Even my old Evos used to spit back thru' the carb fairly regularly
As a point of note , not all Calibrations in the various cal file lists have the ACR's toggled to "on". Maybe that ?
Getting cold so I've retired the bike till spring for maintenance.
I pulled the filter housing and checked to see if the injectors squirted any fuel when I hit the run button but there was no evidence of fuel.
Is there a better way to check the injectors on the bike?
I dunno but if you have a leaking one then while the bike is off it will slowly leak while there is fuel pressure and if it hasn't evaporated by the time you start the bike it could give a snort or more
Brash . Which age range does this recall you mention apply to ?
Could you post a link to this info' ?
Looks to me that the 621 calibrations in the Supertuner Pro are for way younger bikes than the OP mentioned
