went riding today w/ the rk. after about 20-30 minutes the engine coughs and misses a few times. rev it up and it backfires. went about 2 blocks and the bike dies. starts and dies several times with backfire out the pipes and through the a/c. pull off and some friends help me disconnect the power commander as i suspect this first and sure enough the bike starts and runs great although down on hp and torque. 01 rk and i have had trouble keeping it at a 1050 idle for the last year. just won't hold-always drops to 600 even after adjusting. now idle is ok and engine runs smooth other than less power. what happened? should i install a fuel pak to get my power back or just leave it alone. waiting to find out about recall on ultra so rk is the bike for now. thanks.
