    250r fork question

    I tightened the bolt's too far on the axle cradle, and ended up torking off 3 of the 4 nuts/stud. Is it possible to drill them out and put new studs in? Or should i say screw it, and get a new pair(85/86)?
    Does anyone have nice pair they want to part with?

    When that happened to me, I simply removed all 4 of the original studs and replaced them with SS bolts. Works just fine.

    I had the same problem, I put small bolts in and it seems studs are better. The bolts came loose and stripped the 4 holes out. I just went out and got a whole new lower tube. Im sure you could drill them and put new studs in or a heli coil, but its much easier to just find a new fork tube and not worry about it.

    I did that once myself, but only to one.....
    Sometimes you get lucky by drilling and using an easy-out and some heat.
    If you have enough to grab onto with vise-grips, throw some heat to it, and it will likely come out.
    Otherwise, I have had luck by drilling a large enough hole in the bolt that just leaves a little more than the threads. This relieves it some, and allows it to be removed easier. another trick I sometimes use to loosen stuck bolts is this........
    If possible, and in your case it is, lay the part so that gravity will allow liquid to flow into the bolt hole. Then heat it up good and hot, and allow it to cool just a bit. At that point, rub some parrafin wax around the hole and let it melt in real good. The wax will take up some of the space when the part cools, and usually allow you to turn the bolt. It stinks like hell, but it does work. If you do get them out, replace them with studs. Usually, the hardware store has them, or an automotive store. Don't get bent at the dealer for them.
