    If you understand the principle of how a torque wrench works,pound/feet etc,you can easily make a torque wrench using something like a fishermans spring scale (small and light) and a tommy-bar (you will probably be carrying this anyway) marked to one foot.
    Simply hook the sping scale around the tommy-bar at the one foot mark and pull the other end of the scale until it reaches the desired weight,say 20lb,to give a torque of 20ft/lb.
    If you applied the same 20lb to a two foot tommy-bar,you get a torque setting of 40ft/lb while 20lb applied at 6 inches (half a foot) would give a figure of 10ft/lb..
    All you have to remember is torque is the product of a mass at a distance.

    I wouldn't leave home without a centerstand and everything needed to fix multiple flat tires. 9 times out of 10, when I have a problem, it's a flat tire. I don't carry a torque wrench, and in fact do not even use on on my bikes other than for some internal engine bolts. I don't use one on the axles, sprocket bolts, or even the valve adjusters if they are screw and locknut. I did recently use one on the clutch basket nut when I installed a kickstarter on my XT225.

    I have found that for most bikes the manual specifies too much torque for the rear axle. You don't need 100+ ft/lbs. on most chain drive bikes 60 ft/lbs is plenty. I have never had a rear wheel move in the swingarm at 60 ft/lbs. This is easily within the range where you can do it by feel and get real close.
