If the TB/ECU has P.N. 16400-NN4-L11, then it's a 2ED.

If the TB/ECU has P.N. 16400-NN4-L31, then it's a 4ED.

The L11 TB/ECU map 2 is tuned to work with the O2 sensor, catalytic converter, exhaust restriction, and intake restriction. The 2ED model doesn't come with a map switch, and uses a jumper in the headlight connector to put the bike in map 2 for all the engine restriction. If your bike didn't come with the map switch, I suspect you have the 2ED model, but check the TB/ECU number to confirm whether or not you have the 2ED TB/ECU.

If you've put the race kit parts parts on your bike, but still have the L11 TB/ECU, I'd expect it'd run poorly (as you are seeing) in map 2.
