so i installed a buell race muffler on my bike ('08 xb9sx) and have ridden it a couple of times (weather permitting). i'v read on here that the ecm will learn the pipe if i ride between 3000&4000 rpm for how long? will it stop backfiring all of a sudden and start running smoother or what? the discoloration on my header pipes is also creeping down towards the muffler. is there a reset or something the dealer can do? any replies would be a big help, thanks
