swanman5454 Posted July 15, 2008 Share Posted July 15, 2008 I have been having an issue with my 1987 FZ700. The bike accelerates well until it hits about 6000 rpm then it kinda boggs down and gets very loud and deep sounding until it hits around 8000rpm then it opens back up and revs the rest of the way out. Any suggestions on what may be the cause would be greatly appreciated. Thanks Link to comment Share on other sites More sharing options...
