    Help needed. Just gone to fit my light mount on my 2010 Tiger 1050 to the 2 bolts under the dash that, I think, are into the lights/fairing. One came out fine but the other seems threaded. Not sure if you can see from the pics but it is a brass captive nut in a rubber mount which I suppose has been over tightened at some point.

    There's not much room to get tools in to drill or cut it off and I've run out of ideas.

    Any sensible suggestions?

    Hi Ade,
    When you say threaded, do you mean the thread in the brass insert is stripped ?
    Or is the brass threaded insert just turning in its housing ?
    Hard to tell from the pictures.

    I take it you mean the whole thing is turning? if so with a ring spanner try pushing the nut to one side and give it a sharp quick turn hth

    It doesn't look like the insert is turning but can't see for sure.

    With the bolt head still tight to the rubber there isn't anything to grab onto!

    I was wondering if I could get the whole thing; bolt, nut and rubber insert, out with a little 'persuasion and replace it all.

    I think the brass insert will be turning.
    These inserts usually have a knurled outside diameter which are a press fit into the plastic housing.
    Once the grip has gone, they will just spin and grip even less.
    Try putting some pressure onto the bolt on an angle forcing the brass insert to 'cockle' in the housing and it may just bite enough to get the bolt moving.

    On that thought (not the drunk epileptic) I could just pull the bolt and insert out and put a new one in.

    I think you will find that it is in a recessed counterbore and will not pull through without damaging the surrounding area.

    So today I had a proper go at sorting out the "threaded" bolt.

    It turned out to be one of the 4 bolts holding the headlight assembly on. I removed the in full panels and nose fairing so had better access. I decided that the only way to get it out was to grind the head of the bolt off. Using a Dremmel due to it being tight for space I started on the bolt head. Before I was able to cut it off the captive brass nut had got hot enough to melt through the plastic and just fell out. I then had to fully remove the headlight assembly, which also allowed me to sort a wiring fault in my heated grips .
    Once removed I had much better access and was able to heat up the nut and re-fit It. For good measure I also added some epoxy resin to hold it in place.

    Job done. Much easier than I expected.
