    Start at the basics. Pull all the fuses, look at them and replace ones that look corroded. Pull relays, look for corrosion and re-install. Next, battery connections, make sure they are clean and after that check all the grounds for corrosion.

    Might not be the issue at all but if you don't do it, any suggestions after this may have you chasing ghosts.

    Chasing ghosts has never ended well for me.

    When was the last time it had the valves adjusted? Had the BBS's cleaned? Had the injection synched? Changed the plugs? And it sounds like that windscreen switch needs a good cleaning or replacement.

    The most frequent cure for Oilhead surging is a meticulous tune-up. Careful valve adjustment and throttle body synchronization are crucial. New plugs help too if the ones in the bike have a lot of miles.

    some faults

    thanks guys , i rebuilt this bike gearbox clutch etc valves adjusted t/bodies also bbs all cleaned and everything set at that time perhaps 6000 km ago i thought the idle was 1500 now is 1200 also what about the exaust sensor was told to disconect, would that have any effect?, my son has just bought a 2005 r1200 gs and r1100 not being used as much so will remove all the tuperware and tune her up thanks once again Jimmy

    If you mean the Oxygen (O2) sensor in the pipe - yes removing that would probably have a detrimental effect, since that would delete one of the inputs that the computer uses to adjust the fuel mixture (the injectors' timing & open duration).

    On the other hand, they do occasionally fail (more often in cars)... Instead of removing it, locate where it plugs into the main harness and just unplug it... If it runs better, from cold startup to normal temp mid-range, THEN maybe consider replacing it. Or just search through these Oilhead threads to find the "how to test" entries.

    Since it's been over 6,000 kilometers since the last valve adjust & throttle body sync, I would not be at all surprised if the throttle cables have stretched a little, requiring a re-balance job.
    1200 rpm is a bit on the high side for the idle of a properly-running Oilhead; 1000 to 1100 after a complete warm-up (ride) is more normal. As Paul Glaves recommends, be meticulous, it will pay off. Also, I strongly prefer NGK plugs to Bosch (although some on this forum disagree with me, that's fine).

    Note that the windshield setup has two separate relays - one for raising, one for lowering. The handlebar switch just routes power to the selected one.

    I disagree!

    it may come to this on the windscreen. I've got a brick with an inoperative screen which I haven'i got too yet.
