Sorry to revive an ancient thread, but I have exactly the same problem. Please can you tell me how you did the jumpering of the injectors to free them up?
Just because I hate it when people ask for solutions and then don't post the solution when they find it, I went ahead and tried something simple at worked. 1) Disconnect the injector connector, exposing the 3 terminals running to each injector. Oragne is positive (goes to both injectors); one neg going to each injector 2) Take a 9V battery with some trailing wires attached, connect positive to the top pin (orange) 3) Tap the negative to each earth pin in the connector. Took about 20 or 30 taps and then - powie - each injector started to make a clicking noise. 4) Reconnect injector cable. Bike started right up with a splutter and a cough! Hurrah!
