18,000km+- bike started developing what seems to be a misfire, symptoms being rough throttle and power fluctuation especially at cruise in 6th or high in the revs in any other gear.
The bike runs iridium plugs and should still be fine for at least 20,000km. Happy to report that I replaced the plugs and the bike now runs way better. Still some roughness high up in the revs in lower gears, especially 1st or 2nd, but that is with the throttle barely open, and is surely to be expected on an electronic throttle.
To conclude, it may seem as if the plugs need to be replaced sooner than the service manual indicated mileage.
