i just did the re-route on my 06 xb12s,and it made a noticeable change in the low-speed-low-rpm area. i had it backfire and refuse to start a few weeks ago,and with the help and postings here,i found the fouled plug syndrome. in the process of this discovery i went ahead with the mod. piece of cake. i have'nt had a chance to do more than bring it home to give the little woman our first putt around town this year[in 20 degrees] and take it to the other shop. i had no idea that it might require a reset, and no info on how to do it. i'm going to ecmspy!
