    something i saw somebody on one of the good car shows on TV the other day, use this at your own risk. small gauge wire that fits into the hole. when you know it fits, pull it out and put a SMALL dab of JB Weld on the end and re-insert it and let it set up, then use a pair of plyers to back it out. i would say the risk of this procedure is high, but.............

    Is it stripped or you just have not found a hex to fit it?
    If the hex is stripped I would first recommend a small torx that is slightly larger than the hex gently tapped into the hex set screw.
    I do this frequently with stripped hex cap screws.
    If you use a drill bit only use a left hand bit and go at it super slow at first to make sure you drill into the set screw and not side wise into the aluminum.
    You can always go to the next set screw size up if anything goes wrong.

    :hi: Something I have done to break loose those super tight set screws on pulleys, is find a couple allen wrenches of the correct size. Heat one up real good and hot and put it in the set screw. Let it heat the screw up and Gently wiggle it back and forth. Then take the cool wrench and try to back the screw out. The thinking is that the hot wrench heats the screw, causing it to expand ever so slightly, and when it cools the "bond" has been broken . I've had pretty good luck breaking set screws loose doing that. Worth a shot :yesnod:

    the head of the hex is so badly damaged i can not get anything to grip to get it to turn i do not want to drill it as it might damage the whole dam thing i might have to get a whole new control or a used one if any one has one for sale and willing to ship it to New Zealand at my cost

    Heat the screw to break the loctite and use a left Hand drill as small as the Hex key - The screw will turn out without damage, Only screw will be destroyed.

    tried this and sadly it has not worked so i guess my best bet is to take it into a repair shop and have them sort it, or is there a way to rewire the reed switch so it comes on with the rear brake switch when i use the hand controller ???

    Didn't really understood your question. That is exactly what reed switch does, it's the way to tell lever is pulled. Or are you saying the wire or wires from the reed switch are broken? The new part costs like $3 if I remember correct. Curtis has those, or you can buy them from net too. It is very common concept.

    Maybe if you had a really small normally closed
    push button switch ( like how the lite switch in your refrigerator works) you "might" be able to rig up something

    I WOULD NOT try to drill it out myself! Take it to shop! One hour fee is cheap, new hand control is expensive! There is time and place to fix your own bike, but do not practice with expensive parts.

    :agree: But depends on your skill level, and what you have for tools.
