Please help! Stumped!!!!
Hey guys i have a 07 FXDB
i am having a very strange problem.
all started after i did a fluid change.
I changed my oil, trany and primary fluid
Replaced my spark plugs.
took a ride downtown and my bike started "conking" out. in high RPMs
I got home, check my plugs and wires, put my old plugs back in to rule out fowl or gap issiues. Still had same prob. this time it started at regular rpm. The check engine light comes on. its intermittent it runs fine for a few secs then runs bad...i isolated it to the front cylinder.
I have replaced spark plugs, spark plug wires, installed fuel pak to map my bike properly, and replaced the coil. nothing has fixed the problem.
if anyone can help! it would be GREATLY appriciated.... im a pretty DO IT YOURSELF guy! plus i dont have the money to take it to a dealer....

It had a very specific pattern..
if i garb a hang full it will sputter! when it does it at normal RPM it is a very consistent pattern...runs fine for 3-5 secs then runs on one cylinder (rear) for a few secs then repeats. i can make it do it.. ya know?
could it be a injector or fuel of somesort

plug wires are a week old. does same thing with new and old wires.
the fuel like in about 6 months old it should be fine....but it is only effect the one (front cylender), oil levels are fine. injector wires could be true. it is just weird how Consistant the pattern is....i dont know what codes it throws i need to find a computer to hook it up to!
P0264 Rear Injector High EFI
P0374 CKP Sensor Not Detected Carb
P0374 CKP Sensor Sync Error EFI
P1352 Front Ignition Coil High/Shorted Carb
P1352 Front Ignition Coil High/Shorted EFI
it threw these codes at me! the last one seems like its the issue im encountering since i already seemed to isolate it to that front cylinder.
i just don't know what to look for now from here? wiering loose or pinched? idk
i did remove my voltage regulator and all the wire harness when i pulled my oil filter

It's the first place I would look due to you saying you just did an oil change. Sometimes my oil filter wrench tries to catch on the wires to the sensor. And yes it's the one right by your oil filter.

#2. Fuel can go south on Ya in about 30 days or less. Don't know if that would cause any of the problems you're experiencing or not tho.
