    Long Story short. Pulled up at house yesterday and a wasp stung me on the arm just as I stopped, cursed and pulled arm up letting go of clutch. Bike jumped forward and dropped.

    Damage other than my ego is the weight of the bike landed on the right footboard and snapped off both bolts holding it in. Both are broken off inside the hole so I cant get any kind of grip on them to get em out.

    I don’t have access to a drill for drilling them out wondering if anyone knows any good methods/tricks to get em out (with little more than a basic toolkit). If there is no way to do this myself what would be a fair price from a garage to get it done (I'd like an idea so I don't get bent over on it)?

    Pictures of damage (sorry for low res)

    Any advice is appreciated

    Take it to you're local m.o.t station it's at a guess £15 worth they'd replace bolts with that price probably less but they'd inspect few outher things that might have been bent out of shape.
    A good ride is any ride you can walk away from, a GREAT ride is if you can use the bike afterward.”

    if there is enough pretruding then use a small hacksaw and cut a slot into it and turn it into a screw. if not then i would go to a garage so they can drill it and hopefully get the ezyouts on it

    looking at the local rust you might have a problem, trouble with easy out tools is they can break if too stuck and then you have hardened steel inside. what bike is it, might be easier and cheaper to get new brackets. otherwise you could get a left hand drill bit and try to drill them out.

    There's nothing sticking out so trying to cut a head and screw it out is off the cards. Guess it's a local garage best quote I've had is £20 to remove the pair which I think it will be as the Mrs will murder me if I go buy a decent drill and the right bits to do the job. Replacing the bracket would cost a fair bit more about £35 for a second hand one or £65 new (it's a pretty large part that holds both sides boards and other things)

    If you've got a welder, weld another bolt to it and it should come undone

    The way I do it is with a tig welder, it's much more accurate . carefully build up the end of the broken bolt with a peak of weld, keep building the peak until it's protruding out of the hole, then slip a 8mm nut over the peak, welding it on, then undo the bolt with a 13mm spanner... if the broken bolt is corroded, gentle heat with a oxy-acetylene torch, whilst twisting the bolt, will free it off.

    Always works, I've been doing them for years...much easier when access is easy, as in your case.... the quote from your local garage is a fair price, you're not getting ripped off.. hope this helps.

    I've used loctite 'freeze off' (Gm Stevens) and some fancy bolt removal sockets I got from the cheap tool shop in trowbridge worked a treat managed to get 6 out of 6 bolts that where so rusted they had no thread and the bolt and nut had rust into one piece on some exhaust studs...... good **** if you use follow the instructions on the can to the letter. i.e it says spray and leave for a Min or 2, ( this time gives the spray time to freeze the offending bolt and shrink and then penetrates at the same time)

    This is the way too go, prob worth £20 if you do not have acccess to tools.
