    I think wat came out of my mouth was spelt more like this > 'fukkit'

    :D


    Might not be enough to grab it ... wat u can see in that pic is mostly just very thin bits from drilling it out ... the bolt was snapped off level
    Ill just drill thru to China as its a straight thru hole ... hopefully it will then just be shards and fall out ... and I guess just retap the thread if it gets damaged in the process

    If the thread is cut through clean - i.e tapped all the way through - then use a small drill to get a start, then go to a larger drill on an impact driver which should catch part way in and start to turn the bolt - some heat from a heat gun will help - hoping that it's not galled part way down because that's a headache you don't need

    On another subject... maybe have a look at Dynojet Power Commander to cure the throttle / tune issues. The guy I use for machining etc is fitting one to a Norton to cure similar issues you mentioned... they have some standard tunes or you can get the full on unit and spend $$ on a Dyno to get it how you want... but only really useful with exhaust mods etc.

    Plan C? D? E?

    Ground it off to make a 'flat' surface but none of the drill bits will bite .. in fact the centre punch wont even do shite

    The 5 minute job that takes 5 hours :headbang:

    Cobalt drill bit?
    Most of the drill bits available at the 'shops' are trash that are flat out drilling wood.

    Now don't blow your stack, but ... the drill is rotating in the correct direction?

    Once the tip has been ground a few times they are no longer hard and will peen over like that.. I guess you have tried small drill bits and working up to a larger size... you wouldnt think that bolt would need to be that damned hard..

    It is possible that the bolt has been work hardened by the previous drilling.. if that is the case it could be a real issue.
    You might need to get the bolt damned hot to anneal it enough to be able to drill it.

    There isnt a lot to choose from in the difference between Tungsten Carbide drill bits and Cobalt.
    Tungsten Carbide dont really work all that well in hand held drills and are more for CNC work etc as they will last far longer.

    Yea the bolt drilled out fine before just with 'ordinary' bits ... its the bloody broken extractor in there thats the problem

    I always start off small

    Previous owners need to be shot on sight

    Do you have a Dremel and some grinding stone's/chainsaw sharpening stone's for it ?
    They should be able to grind away the broken easyout and then you can go back to using progressively bigger drill bit's
    It'll probably take a few stone's to get the easyout out

    As above.... OR ...... a small Cold Chisel and use the corner into the edge of the Easyout in the opposite direction to what the easyout goes... the shock should be enough to break the bite....

    Yea Ive given up for now ... I needed the tank etc back on so I can get the main fairings sorted and a few other things
    I was thinking the same ... I have a dremel and some sort of crater in the centre for starters would be good as 'slippage' is a big issue when u attempt any sort of force downwards

    Its pretty much a shiny flat surface now and u cant even see where the extractor starts/ends and the bolt begins

    The only success was buying these ... very handy on this bike ... cheapos but do the job

    Got that screw remover set from Bunnings also .... sausage sandwich was ok too :)
