Default JDM Spec F4i, 180KMPH Restriction

Dear All members , i have a F4i here in India and unfortunately the bike is restricted to 180KMPH being JDM spec.
Can anyone help me with a quick and cheap fix to the restriction removal?

I would find an on-line OEM supplier and compare part numbers. It might be as simple as replacing the ECU and thats it.

Here are the pics from from the actual japanese spec F4i the intake manifold which carries a restrictive plate, we will be removing this plate too.

Speedometer is designed to show only 180KMPH and even the self check is only upto 180. Does any one has the circuit diagram of the speedo mother board? or someone can send me pics of the US or EU Speedo motherboard to match with my JDM F4i?

If you're sure that's a restrictive plate, you could start by replacing/removing that. Secondly, an ECU flash or simply buying another ECU/Ignition could be your ticket!
