How to turn off check engine light?

I just flashed BS2-8591A-10 ECU, bike runs good (still need to increase RPM's) but I got this yellow terror light always on. I need to turn it off ASAP because my client is getting nervous.

Regards,

You need to get an OBDII scanner and adapter harness to find out what the fault is, correct it, and then reset it via the scanner. Most bikes that are OBDII-compliant cannot reset error codes without the OBDII scanner.
