I think on bikes the only ones I torque are the main bolts that hold the engine together
internal bolts and the head bolts
all others by feel but I've been working on small bikes for a while now and really don't recall even breaking any bolts
the z runs very smoothly so I don't predict any bolts just vibrating out on there own
and every bolt so far I have taken off I do put a drop of blue loctite on them as a precaution
why I buy it in large bottles, I use that stuff a lot
now if your new to working on bikes, you can also cause harm with a torque wrench too if you don't know how to use them and there is a trick to using them
especially these very low torque bolts when you get into in lbs you should use a very small one with a short handle and 1/4 inch size
also using the correct size ratchet can prevent breaking off bolts as you don't have too much leverage
Usually I try to use 1/4 ratchet for 12mm and smaller bolts/nuts
and 3/8 ratchet for 13mm-17mm
and larger I use 1/2 inch ratchet mainly because after 17 my sockets are 1/2 inch size anyways and really on the z probably the axle nut is a 17 or 19
nothing larger I don't think
stay away from using 3/8 ratchet on the small sizes as you can over tighten much easier as you can't really get a feel using such a heavy wrench
and please if your new don't use impact guns, leave that tool for the professional
I've seen so many people just destroy nuts and threads on bikes with an impact gun
that really takes a skill on small bolts to use that tool
