    My good friend was recently in an accident on his pristine 88 R100GS. The force of the fall sheared the steering stop on the frame off. I can weld it back on, but I'm concerned about the electronics. What do I disconnect, remove, etc. Thanks for your help.

    I was always told the diode board was susceptible to damage from welding current.
    better safe than sorry.

    I'd go slow doing maybe 1/4 at a time then let it aircool. Don't want anything warping up there or heating up the steering bearing grease.

    Off the map,
    I agree, the two things I welded on my g/s was the rear muffler mount, and the kick stand plate, the ground clamp was within 6" of the welding surface though.

    I did disconnect the negative the the battery and ICU.

    Ive welded on mine before and only ever disconnected the battery. Keep the welder earth as close as possible to where your welding. As you will be so close to the steering head bearings, are you pulling the triple clamps out ?

    I hope to keep it together. Just tack and let it cool. If grease starts running out, I'll take it apart. Thanks all for your help.

    I've done this a couple of times and removed the front end to gain access and make a neat job.

    Of course with the front end off and a welder handy it's pretty easy to throw in a set of bearings.
    Disconnecting the battery should be enough but with the front end off why not disconnect the diode board as well.

    Usually I discover little things along the way like chaffing in wiring looms , grunge that can't usually be got at or a better way to put it all back together so that cables don't rub frame paint.

    Excessive maintainance is what keeps these things pristine even if it does take all weekend to do a 30min job
