Bolt Sizes?

Is there any place that lists all the bolt sizes on a KZ650 motor and frame? I haven't worked on a metric bike in years so I'm clueless as to the size and pitch of their threads.

Buy a metric pitch gauge. Most bolts are M6 with 1.0 pitch and M8 with 1.25 pitch. For instance, the larger nuts on your shock studs are M12 with 1.25 pitch which is an oddball size. You will also have M10 and M12 bolts/nuts on your bike with different pitches you will need to measure. There are a few M5 screws on the bike with .8 pitch and some smaller fasteners on the carbs.
