I have 2008 busa I just got from a guy. It has a full yoshimura exhaust. With a power commander and it has about 1800 miles on it. My problem is i heard a strange noise tonight riding. Took it home took side cover off and ran it and the pipes up by the head started glowing red hot. The noise sound like it's coming from up by the top of the head. Anyone. any help would b appreciated.
