The CB1100 Community Forum

Hi, I have Honda CB 1100 2014. I bought it brand new the summer 0f 2016. I had Yoshimura 4 into 1 and race tuner added to the bike when i took it in for 500 mile tune up/ oil change. So, now I have about 2,000 miles on the bike. So the problem is once I start out on the bike it works fine. After about 3 miles, it starts bucking. The faster your going the more noticeable the bucking. I'm assuming that's when the computer shuts off the choke. Does anyone have a clue what this could be? I don't want to take the bike into the dealer if someone out there has the same problem and can offer advise? Sometimes the bucking goes away and sometimes it stays with me for the ride. Maybe i should disconnect the power commander and hook back up the factory computer and see if problem goes away? The bike works fine other than this annoying problem. Maybe the bike needs to be re flashed as now the bike got a lot louder all of a sudden. BTW the exhaust system finally broke in and sounds awesome. I was really disappointed at first because the exhaust systems sounded the same.

Not sure what the issue could be, but there is no choke with fuel injection. The computer changes the fueling as it warms up, but there is no choke.
I would first take the PC out and see if that cures the problem and go from there.

couple of Q's. You've had the bike a year. You added the pipe and electronic gizmo at the 500 mile service. Then you put 1500 more miles on it.

When exactly did the bucking start?

Since it took a year to put 2000 miles on a now 3 year old bike, could it be an old fuel issue? (not sure how often you fuel up or ride). You might try a dose or two of seafoam and ride it long enough to let the fuel treatment do it's work (clean the injectors)
