For a while now, I've felt a rough idle on my bike. (2008 ST1300A w/46,000 miles).
I'm thinking this started before I installed the FCE but that's on my list of troubleshooting.
I just did a valve check/adjust this week. Everything was within the tolerance limits with the exception of a left-side intake valve and that was brought back into the middle. All the numbers were either dead-on or on the loose side so I don't feel that is contributing to this.
I can put my hands over the right and left exhaust pipes and the right just doesn't feel like it's pushing 'as much' air and it sounds like it has a 'miss' to it.
Easy stuff:
I did replace the plugs on the right side with new ones, didn't make a difference. I also put some sea foam in the bike for a couple tanks and that didn't clear things up either.
My 1st thought was ignition coil - however, I put all the plastic back on before thinking to switch the left/right coils to see if the problem then showed up on the left side.. doh!... I don't have time this week to try that but did find a used coil very cheap so I should have that on hand when I try that test next week.
The other thought is the fuel pump of course but I'll go to a dealer for that one as a warranty issue.
Before considering the fuel pump, and after trying the coil switch, I'll disconnect the FCE to see if that makes a difference. I haven't heard of anyone contributing this type of thing to the FCE so I don't really believe that's the issue.
Anything I'm missing? - pun intended.
