Since removing the zard exhaust and power commander from my 05 1050 its not wanted to start. It spins over quick eneough but takes an age to catch. After removing the Power commander I noticed that I have a grey plug which comes off the loom under the tank that doesnt seem to go anywhere. I assumed that this is just for diagnostics but can anyone confirm this for me. As I didnt fit the PC I cant work out whether it was meant to plug in anywhere. thanks in advance.
