1998 Banshee starts right up first or second kick... She wont idle until I'm riding for about 5 minutes an when i stop it will some-what putt/idle for about 3 seconds then shuts off, but will fire right back up with one kick... I have also noticed that when im looking at her from behind smoke comes out of my right silencer and not my left.. I put my hand up the the left one an only feel little air coming out of it.. Just put new plugs in it, its jetted and its running on 25 to 1 gas ratio.. Any suggestions?
