Yes the 13's harness is different. I have flashed a couple of B-Kings and Busa's the k13's harness is super clean when you take the seat off.
If you are going to flash one you have to use the harness that Gofast mentioned.
I know, I have a bench flasher, makes it easy, no jumper needed
I've put a jumper on my Busa and B-King, and a couple others, but just saves time to pull the ecu. Unless the bike is going for an ecu ed dyno tune, then of course you need the jumper harness on it.
Done 12 Busas and 4 B-Kings now.
Just basics, Smart TRE enabled and top speed limiter gone, stp's opening rate increased and 1st/5th map copied to 2,3,4,6 with 100% fueling, fuel soft cut removed, fans on 10 degrees sooner. Same flash on the B-Kings just with B-King gauges enabled.
B-King's had cold air intake mods(as the stock box sucks)and exhaust valve(exvac)opened too.
Amazing what clicking a few buttons and a 4 minute flash will do.
