Bike has started running badly, following symptoms:- Starts from cold but if you leave on idol, engine will stop after 10secs (it slows down just before it stops) It seems a bit dirty off the bottom, if it had carb you would think pilot jet was blocked, when you blip throttle it bogs, ok if you wind on slowly. On the track it is low on power and just doesn't quite run right. Fast idle does nothing and turning to adjust idol does not seem to do anything either. I have taken all the plugs apart I can find and they all look OK. Any ideas? I thought there may be some dirt in the injector but not sure if I should take it apart as it is not in workshop manual. No errors on FI lamp. Any ideas?
