    Hi Everyone, recently brought an immaculate 07 XB12X with 41k on the clock. Been well serviced by a fussy owner. I really like the bike and quite happy with all of the Buell quirks like fan coming on, hot right leg, clattery engine etc, thats what I signed up for. I have noticed that the bike can be a bit off putting with the following:
    The bike sometimes coughs and misfires coming off idle like coming away from lights and a bit scary if low speed turning.
    Holding a steady speed around 100kph, she gets an intermittent misfire and hunts (surges) a bit. Still quite ridable but feel that the tuning could be a bit better. Absolutely no issues if riding hard and accelerating, just when holding low load.
    I also find it quite hard to ride the bike smoothly at low around town speeds, throttle seems overly sensitive. Any thoughts. Cheers, Stu

    you have an endless No of options to overcome this common problem:

    1) Race ECM or do-it-yourself-re-map
    2) K&N filter
    3) Hawk muffler
    4) better spark plugs

    These will overcome ur issues

    Low speed stuuter is generally resolved satisfactorily with "Breather Reroute", the other minor issues can be "Tuned Out" by ECM Spy or Tuner Pro, or for plug and play, an EBR ECM, I have the reroute and EBR options on my '08 and been quite happy with how mine runs

    Like they said, spark plugs (NGK# DCPR9EIX), breather re-route should help. Also here's another mod that tends to help: Ground Mod.

    Here's some How-to you might want to look into: Spark Plug Change and Breather Reroute Mod. There's also a vid on here for the plug change.

    Without custom mapping like datalogging, it's almost impossible to completely rid the Buell of it's stutter in all RPMs.

    R the NGK's cheaper than the buell pro-series split v plugs?? i popped a set of da pro series in and they seemed to clean up some of those issues, but they were like 7bucks a piece.

    NGK's are a little more costly, I think mine were 9 apiece

    Ya mine were like 9-10 bucks a piece and well worth it. Pretty sure the majority of the people on this forum run them

    Don't pass on the NGK's, they're Iridium and are very resistant to fouling when compared with other spark plug metals.
