    hi there jsut wondering ive been searching for some info on similar problem bike idles fine accelerates great but makes more of a not so much shudder feeling but more like a car that has water in fuel and im trying to work out what may be causeing this?  i did have some water in a bad batch of fuel and ive had the tank off twice and cleaned all filters etc im trying to eliminate possible problems. maybe my fuel map is dodgy, or o2 sensors are buggered or running too lean, im not sure about this but bike is very jerky sometimes when im just cruising at like 50 and trying to just cruize but its fine at 100 and at 60 so any help or comments would be much appreciated.   my bike is a 07 1200 custom sporty with s&s slip ons

    i have cleaned the filters in the fuel system but i have got efi so im thinking maybe the injectors have some dirt in them or maybe some loose wiring somewhere will go over the bike on my days off and see if i find any loose wires
