1998 banshee with few mods. Was running perfect. Started sputtering. Left side cylinder is not firing. Can't figure it out. Last week replaced top end and yesterday replaced ignition coil. Have checked reeds and they appear OK (not sure what this means but when I removed reed cage, the intake port on right cylinder was moist and dry on left side. Could it be carb problem? Also, when I place my hand at the end of the silencer on right side you can feel heat - Nothing but a little amt of cold white smoke coming from left silencer...I'm lost and downtime hurts! Any help would be greatly appreciated
