Intermittent Engine Light

Bike (S2R800) has been in the garage for a few months hooked up to a C Tek charger. Took it out for a ride today, fired up first time no issues but the orange engine light came on. Bike seemed to run fine so I took it out and after it warmed up the light went off, however it came on again a few times during the ride. It would stay on for a few seconds then go off. As mentioned the bike is running fine. Any ideas?
