If you are speaking of the stumble around 3-4k rpm. install a jet kit in the carbs and it will smooth it out alot. I also have a 95.. K&N filter, Kerker exhaust, ignition advancer, and sprocket swap. If you have never cleaned the carbs that would be something I would advise.. I run premium or race gas only and I had some pretty gummed up jets last summer... Should be good to go this year....
