Time to change the plugs...was hoping to do the job tonight. Called the dealer for a part number, they gave me NGK CPR9EA. I have been around bikes for a long time..I have never heard of a model CPR. Dealer said it was not in their system. I called Advanced, it was not in their system either. Anyone replace these yet? Where did you get them? I noticed a couple of threads where guys are using IR plugs now...what part number are you using? Thanks for the help.
