Reply To: 650 gtr won’t idle and misfiring
With fuel injection if the voltage gets low the ECU will try to keep the main things running as long as it can which is why it will start to mess about, the fact the bike ran fine for a bit sounded like the battery was discharging so to me the first thing to check. Now it’s going to be a bit of detective work, it could be something as simple as a loose or damaged plug cap or coil or a sparkplug so that’s the next things to look at.
