How do you tighten the chain on a Suzuki Z400?

you put the back end on a jack then u undo the two bolts that hold the brake caliper on. then on top of the swing arm there is 4 bolts loosen them up.

on the back of the swing arm you will see 1 or 2 bolts depending on the year just tighten them up and then tighten the four on top back up and put the brake caliper back on and you have tightened the chain
