Hey guys and gals, I have a 2008 V-star 1300 with a power commander III USB and cobra short straight pipes (Both dealer installed). When the biek sits for over 1 hour, the bike will not start, just cranks. I heard that there is something with the power commander not sending a signal to the fuel pump. Does anyone know if that is true and if so how can I change the map settings in the commander. Thank you all. Djsonic
