Install a regular style master link, iv'e never busted a chain while riding with a master link fitted.
Tighten the triple tree up till you get a slight drag and i mean slight, use two fingers to push the bars when turning from lock to lock and don't forget to loosen the stantion clamp bolts when adjusting the head bearings ( you won't move the trees closer together if you keep them clamped). I would loosen the lower clamp bolts and leave the top ones tight. Make sure the wheel spindle is clamped correctly.
Make sure the wheel is straight and the bars aren't twisted to one side and "pump" the forks up and down to allow them to settle in the correct position, snug up the lower bolts and check for straightness of the front wheel. Don't forget the upper tree has the adjusting nut/ring and then a nut to lock it all together.
Snug up the swingarm till you can't feel any side to side flex, best done with the wheel out or at least loosened to allow movement when adjusting the swingarm . Hope this helps you, Des.
