Taking ‘93 RS for first decent ride. The bike is now idling at 2,000 rpm when warm. It didn’t do that on prior short trips around the section. Also, as I just pulled in and turned it off, it will not light up…all went dead. Checking fuses first. What might cause the idle to suddenly increase? When flipping the throttle to get it to then drop it will set at a higher rpm. Cables are looking okay, starts fine and idles fine initially. Appreciate any input. And for the life of me not sure where you’d connect tubes to balance carbs as there are no visible ports to access. Valves are set correctly, new plugs, new air filter…what the….?
