Lately I have had the gas like smell coming from my bike when it’s running. And I’ve done a little research and what I’ve found is that my bike is probably running rich. Since it is fuel injected I don’t quite know how to remedy this problem. I do have aftermarket exhaust on it but that’s it, as far as I know everything else is stock. How can I fix this running Rich on my fuel injected bike? Any tips?

i think for FI bikes you buy a fuel management control device, i think its called fuel processor, you plug that into the wire connection on your bike and you program the fuel map pots, its numerical numbers, this new fuel processor unit manages your fuel intake, there are some fuel processors that can just add fuel and some that can add and subtract, not sure how they work, i think you hook up the processor first to a laptop computer, adjust the pot numbers then plug the processor into your bike

I wouldn't go by smell. Better to take a look at the plugs. If it is running 'rich', that's an indication one (or more) of the sensors is malfunctioning or the wires connecting the sensors are faulty or have dirty connections.

I’m a little new to motorcycles mechanics/maintenance so when you say sensors, what sensor are you talking about?

FI bikes have sensors that send signals to the electronic fuel controller that manages when and how much fuel is delivered, carb bikes don't have these sensor, which i think on FI bike is at the exhaust, the air intake and the throttle

There are a couple of pressure and temperature, and throttle position sensors which the ECU 'reads' in order to set the proper mixture for any given 'condition'. Within limits, the ECU 'tests' the sensors to ensure they're working (ECU uses this to display a fault code) but the ECU has no way of determining if the sensor is 'working' yet providing an incorrect 'measurement' (which could be caused by the sensor itself being faulty or a wiring/connection/corrosion issue).

my bike is carb with no sensors, but I found this on youtube for you, it looks like he is checking the codes using an adapter and a scanner from ebay

Scanner not required as the ECU provides the codes. In any case, there won't be any codes if the problem is wiring/corrosion or just a wanky sensor.
