ok guys...got an 04 XB12R...ive done breather reroute...has a D&D exhaust, race map, K&N air filter, DCPR9EIX Iridium spark plugs, new spark plug wires.
this bike has always had a stutter problem if you would call it that. anything under 2500 rpms...but only when keeping a steady speed or BARELY accelerating (like an 1/8" throttle or less)...if you are accelerating any more than that it doesnt do it. and it only does it under load, wont do it just sitting on the kickstand. it almost feels like someone has a rope tied to the back of the bike and is tugging on it is the best way to describe it. ive checked for intake seal leaks as well...but nothing i do seems to fix this. no error codes ever, ive tried moving the ground coming off the battery as some suggested. no luck. AFV after a few months only went to 104 so the race map isnt the issue. ive also checked the static timing.
ive just got the bike back together after a drunk driver totalled it out when sitting in front of my house. it has approximately 25k miles on it. just looking for futher suggestions. i appreciate any help you guys can give me.
P.S. i also have an 03 XB9R and it has none of these issues
