Align a yardstick with your countershaft center, thru the swingarm
pivot center, and out past the axle. When those axis are in-line,
the sprockets are farthest apart. Compress your suspension until the
axle lines up with the yardstick. Your chain will be tightest at
this point.
For you budding engineers: a hefty pal and some tiedowns are more use
than calculus.
