dude, that won't work it will still be confined by chain guides, the front of the swingarm, the frame, etc. if there's no masterlink, you'll need to just pick any spot on the chain easy to get to, and grind off the rivets and pop out that link to get it apart. if done carefully, you can go to the stealership and get masterlink to put it back together if you are reusing it. just give them the make and size, which is usually stamped on the plates of the chain. otherwise just grind the shit out of it, and pull it apart. and definitely replace chain and sprockets as a set if any are worn/damaged.
