Re: I need specs...
The UK version wont have PAIR or what ever its called re emmisions, nor a O2 sensor either (not all USA versions had this either iirc). the lights are not wired on with the ignition which I think USA ones are (2003 uk onwards 954 are too I beleive). USA doesn't have HISS so that's not covered in there manual.
I should think all the torque settings, engine internals, plugs, valve clearences, clutch, brakes, oil, forks, shock, wheels, etc will be the same. US manual will probably say front/rear sprockets are 16/43 but UK is 16/42. I'm working from a US version with no problems.
