Honda NT650 Hawk GT chain slack tool

So you've lost the chain slack gauge, or didn't get one with your bike.

You can make one!

Here's a picture of the whole thing.

and here's a closeup of the business end.
Peter Paulovits in Germany reminded me that most of the world is metric, and supplied the appropriate numbers:

	Metric               English
	A  = 33 mm          1.3 inches     or   1-5/16 "
	B  = 43 mm          1.7 inches     or   1-11/16 "
	C  = 53 mm          2.1 inches     or   1-2/32 "

And here's how to use it.
