Here's the drill if you really have to know. Put it on the
centerstand (you have one, don't you?). Pull the bottom linkage bolt
from the dogbone links. Move the rear wheel through full travel and
note the minimum chain slack encountered. A floor jack under the
wheel will help. The minimum chain slack encountered should be
minimal, about 1". Adjust chain to achieve this. Reconnect linkage
and note chain slack at full extension. Adjust chain to this amount
of slack forevermore.
On my G.I. Joe KLR this optimal chain adustment is obtained when the
top of the lower run just clears the rubber chain guide strap which
wraps under the swingarm, equating to 63mm of midway chain slack
(book says 60mm max, close enough). Doing this on the sidestand is
fine. My KLR rear suspension is at full extension on the sidestand.
Points of interest. The KLR swingarm does go overcenter at full
compression, but because of its length and the short
sprocket-to-pivot distance the chain slack hardly increases from the
minimum encountered. The above determinations will change somewhat if
you change sprocket sizes or suspension geometry.

In the absence of an handbook, can somebody tell me what play there
should be in the chain. I know most bikes it's 1/1.5 inches; is this
the same for the KLR?

The book says 2 to 2.4 inches. Then get a fat guy, like me, to sit far back
on the seat to compress the spring as much as possible. Then you should have
1/2 to 3/4 inch. Roll it half a turn of the wheel and check it again. Loose
is better. You don't want it too tight and damage the counter shaft.

Ipve just adjusted my chain for the first time (used bike, 4000k miles). I
put it up on a stand and set the full up-down to 2". My book says to do the
2" thing on thte side stand. When I sit on the bike the chain has only a
small amount of play. It's not tight, but the suspension isn't all thte way
down either. How much pressure should one use to check the free play?

When I check the free play on my KLR, when the bike is on the
sidestand, I can push (pull?) up and the chain will JUST touch the
bottom of the rubber slider on the front of the swingarm. IMHO a
little too much free play is better than too little...

Personally my bike doesn't like anything tighter then 2.5 inches. I
have cut into the bottom of the swing arm with the chain when it was
at 2 inches. it will also feel like there is less travel in the shock
becaue the chain is hitting the swingarm

What I believe to be the universal adjustment
recommendation is as follows:
Adjust the chain for ~ 1" of play under these
conditions - depress the rear suspension so that the
center of the countershafk sproket, the swing arm
pivot and the rear axle all are in a straight line.
When measuring the play have the motor in-gear and
roll the bike slightly back so that the upper chain
run is tight, all the slack will then be along the
bottom run.

That's not right Deacon. If you had gone through all the trouble to
do it that way, (and that IS a bunch of work to check a chain) and
your countershaft sprocket and rear axle is level with each other,
that is the FARTHEST that the chain is going to need to be extended.
If you still had a whole inch of slack anywhere on the chain at that
point, your chain would be too loose. If you did it that way the
chain should be fairly taught, with a litte "wiggle room" and that's
it.
But let me tell you the super de duper, easy, secret, KLR yahoo list
way of doing it.
With the bike on it's side stand (the way it will be when you walk up
to it 99% of it's lifetime) bend down next to the chain and grab a
rock, stick, cigarette butt, WHATEVER, (to keep chain crap off of
your hands) and push the bottom chain run upwards, straight up to the
back edge of your black chain slide. The rear part of the chain
slide wraps around your swing arm and the farthest rearward edge is
right in the middle of your chain run. With the correct 2 inches of
slack in the chain, in this position, the chain should be easy to
push up to within about 4 or 5mm of the chain slide edge, and then
you should be able to use a bit more force and push the chain up to
just barely touch the chain slide edge. If you can't touch it, it's
too tight. If you can touch it easily, it's too loose. It's just
that simple.
I have used this method extensively after double double checking with
a ruler that it works correctly. It does, and I find it extremely
easy and quick to check my chain many times a week.

How fanatical does one need be about their chain? I
try the 2" ruler method, but am never convinced that I
have it dead on. I realize a chain way out of whack
can ruin sprockets, and gouge channels, etc. I just
adjusted it a few days ago, and I check it about once
a week when I wash and lube it. Is this enough? Now
you got me paranoid... lol. Is good nuff good nuff?
