Thread: "THE PROBLEM" noone knows how to fix

  1. #1
    i have posted here before stating that my 06 xb9sx has been running "rough" (other thread)... it was huccuping, laggin throttle.. etc etc etc.. and the harley/buell shop has done absolutley EVERYTHING to the bike minus tearing down the engine and putting it back together... (cause quite frankly..im not paying a fortune to get the engine torn down and rebuilt).....

    most recently i ordered a programmed race ecm offline with everyone thinking that it was the last thing we could do.. it didnt work.. so im left with a huge bill to pay and STILL a bike that doesnt run right.. i have NO IDEA what to do anymore.. anyone got anything



    edit: locked other thread and posted link here to have complete history and no dubble posts

    Do a TPS reset and put in new fuel and new spark plugs. If those dont work, look at your fuel pump.

    done it, done it, and done it....none of those things worked... ill double check on the fuel pump,,but im for sure they already checked that too...

    well the shops its at is an hour and a half away... but it runs rough ALL THE TIME now... it used to do it after 10 minutes or so of trouble free riding.. and after i took it to the shop and they started getting into it, it just got worse.. now it runs rich/rough all the time

    Normally, whenever its a progressing issue, it's the fuel pump.
