Over the last couple of days I changed a few things. Put on bar end mirrors, replaced chain guard, put in Iridium plug and replaced muffler with a taper silencer from Hitchcocks. Mirrors work great, I did retain the original bar end weights. Mirrors clear as a bell up to 75 mph. Question: I've ordered a Power Commander V through a local independent bike repair shop (old racing buddy, he even has a Bullet he rides occasionally). Does anybody know where I can get a map just for the pipe mod? I have not changed the air intake, plan on doing that later. Bike seems to run OK, may have lost a couple MPH at top end.
