    Is this the type of chain breaker you are talking about? If it is I hate these things. For years I have always used a bench grinder to shorten chains. Just grind the ends off the pins, and tap it apart with a punch. Any kind of grinder will work, even a dremel tool.

    Wish I knew how to describe the parts but lets just say that the master link is a male. You want both ends of the chain to have the female parts (the parts without the outer jacket)
    In this pic the top would be the male and the bottom would be the female. The way the chain is now, it will go together with just the pin and that is OK but if you wanted to use a master link the outer casing would have to be removed.

    I think I am understanding.. but maybe not. Every other link in a chain is either wide or narrow. The master link is wide. You need to take one more link off, or put one more link on, to make both sides of the chain thin so that you can connect the master link to it. Does that help?

    I put a nut under the chain and tap out the pins halfway with a centre punch, works great. To rejoin, just tap the pin back in with the hammer.

    That's how I do it too Tiger , with the nut but first I squeeze the pin flat with the chain with vise grips so that the punch is easier to centre on the pin when hitting it with a hammer. I remember grinding the ends off the pins thinking they were mushroomed but they are not. I had such a hard time believing it.
    Once you get over your fear it's a five minute job.

    I would think your chain is either way to tight or has to be rubbing on something, or the master link hitting something. I have had 5 motorcycles and for Motorbikes and never broke a chain at the master link. That is what I would look at first.

    Other than you putting the clip on the wrong way, I really don't know.
    The closed nose of the link should go with the direction of travel. The other way, the clip can catch and release itself.
    Do you have a link or two left from your kit? Go with no link! Read above....hammer,punch and a nut under the link/pin. It may seem hard but once it moves, you will see. Vise grips work great to close it when on the bike.
