You might find this evaluation of the Chain Monkey, which is supposed to help you set your final drive chain slack, interesting - even if you decide not to bother getting the thing: http://www.webbikeworld.com/t2/chain-monkey-review/ (http://www.webbikeworld.com/t2/chain-monkey-review/)

Being a total gadget whore, I ordered the thing.
Tried it for 1 day and, after my neighbor wouldn't take it, threw it in the trash.
The rubber bolt cover abrades immediately: no big deal, since it's really not needed.
Once tightened according to directions, and then the chain is set, the bolt is really very hard to get loose. No big deal: just remove the handy plastic knob, exposing the hex head on the bolt and use a socket wrench and ratchet handle.
But the deal killer for me: The chain was way too tight, when using according to directions, and when I compensated to where it was about right, I found that I was pretty much just doing my usual SWAG approach, which I'm good at and which has worked for many years without no fancy gadget.
Summary: A solution in search of a problem; that creates more problems than when I started.
But then you may like it just dandy.

I plan to stick with the tried-and-true method of measuring chain slack using my dirty finger and a ruler. But I do all of my chain slack measurements and adjustment with the bike on its center stand, as it is just easier to do and I haven't noticed any difference between measured chain slack between performing it on the center stand or the side stand. ;)

I've read that the purists want us to measure the slack while sitting on the bike, and in several places around the rotation of the rear wheel. A two person job.
I'm even more crude: on the center stand and no ruler... just a dirty finger and my best eyeball guess, with the OEM specs as a starting place, erring on the side of loser rather than tighter. My FJ-09 owner's guide specs, e.g., are WAY too tight (5-15 mm) for my preference of saving my bearings. I adjust to about 1" at the tightest spot in the rotation. Caveat wrencher!
