GL1000 been running great, then went to hell. 200 miles on carb rebuild, valve adjust, new timeing belts, and new ignition. Thought maybe fuel filter... nope. Notched gasket on fuel cap... nope. Petcock?.... nope, drained tank and blew in air, seems ok. Got fire at all 4 plugs. Opened ingition and all seems still tight so it didnt move... did i miss something? Help.... :head bang:
