I have a 2009 xb12s lightning. At 2500RPM it seems to have a slight miss. Every once in a while it will miss and act for a second like its going to die at 65MPH. Why? I wired the exhaust butterfly wide open. I had read that someone else on here had done the same thing, could that be the problem? I got the bike with a broken exhaust header,what are the chances that I have a burnt valve?
One other separate item. Can someone please tell me how to keep the damn mirrors were I put them? After about 5 minutes at 50MPH the mirrors push inward.
Thanks for the help,
Walter
