so yesterday at work i'm putting together my bike plastics..started her up..everything seems fine besides a whirring noise i'm hearing..hopefully it'll work it's way out..listening to that power freeflow exhaust..ROAR..ROAR....this guy is travelling passing by on the road hears my bike...turns around & pulls into my shop & begins answering my revs he's riding a xjr 1300...I switch off & look at him & he's just smiling back & says when u come out i'll catch you!!!....should i be afraid?
