1BAD2K Posted March 17, 2017 Report Share Posted March 17, 2017 They probably have a 4 bolt throttle body. Also, I don't thing the ports will match up. Theirs will probably have rectangular port heads. Quote Link to comment Share on other sites More sharing options...
2003_SuperSport Posted March 28, 2017 Report Share Posted March 28, 2017 Different fuel system too. 2003 was a return style fuel system. Quote Link to comment Share on other sites More sharing options...
