I had the same problem with my 2003 ST 1300 at 100,000 klms and put in some injector cleaner (which also dissipated water) and changed the fuel filter in the tank.... Problem Solved..
Now at 200,000 klms I have the same problem, just changed the Petrol filter ( which had some water in it) and introduced some more injector cleaner and the jerking missing problem is again solved.
Only CASH and new parts will solve the engine management light coming on my friend.
Hoipe this helps
