I just bought another bike.Didnt want to but was to good of a deal to pass up. 1997 yamaha virago xv1100 with 3000 miles yes three thousand miles. original owner. I knew it was gonna be a lot of gum and gunk in the tanks yes it has two gas tanks and carbs.the bike is in awesome shape. but the gunk turned hard like epoxy.the bike had not been started in 8years and not much before that ether does anyone know of a solvent or such that will remove this stuff.
