Picked up my new 2008 XB12Ss on Thursday.first thing i noticed was a rough idle and poor throttle response.This only happened from idle to about 2000 rpm.Took it back to the stealer on Friday.It took the service dept. 3 hours just to look at the bike and another 3 1/2 hour to diagnose the problem.
They determined that the TPS needed resetting, but did not know what to reset the voltage at.(no Service Manuals for the 2008's yet!!?) Anyway,they shotgunned the problem and the bike does run good but could be better. Overall i'm very happy with my purchase. AWESOME bike.
