The front sprocket is held on by a big-ass nut. Put the bike in
neutral and take off the front sprocket cover. Bend the retainer
washer flat with a big-ass screwdriver, then get a long piece of 3/4"
galvanized pipe (3' is a good length), put your socket wrench on the
nut, put said pipe over the handle of said socket wrench, hop on the
bike, jam on the rear brake with your right foot, and heave upwards
with your left side. It'll feel kinda springy (the chain does that),
just keep heaving you won't break anything (and if you do, you wuz
tryin' ter get rid of that chain anyhow, right?), and eventually the
nut *will* give. When you put the nut back on you'll follow the same
basic procedure, but will be using a big torque wrench (click-type,
you can't see a dial or needle in this situation) and of course be
pushing down rather than lifting...
The rest is pretty much common sense. You'll need to take the rear
wheel off to change the rear sprocket. Don't try taking the front
sprocket off altogether until you take the rear wheel off and break
the chain (you'll need a chain breaker, unless the old chain was a
master link type), otherwise it gets hung up in the chain and is a
PITA to work out of its little area. Similarly, put the front sprocket
on before you start installing the new chain. If you are installing a
rivet-type master link rather than a clip-type master link, you'll
need a chain riveter also.
Personally, I run a clip master link type chain and have never had a
problem (the KLR isn't exactly a powerhouse!), the secret there is to
use a small socket and C-clamp as a press to shove the side plate on
securely before trying to put the clip on. Most problems with the
clips coming off are caused by people not pushing the side plate on
enough, so the clip doesn't seat all the way in its slot. If you
haven't pressed the side plate on enough to see the entire slot plus a
teensy bit of metal on the other side of the slot, you haven't pressed
the side plate on far enough to put the clip on.
The "gold standard" appears to be the D.I.D. Gold, but my suspicion is
that any good-quality X-ring type (not O-ring type) chain will do
quite well on the KLR. Actually, the O-ring types will last pretty
well too, but tend to have more horsepower-sucking friction and hey,
it's not as if the KLR has a surplus of horsepower to begin with...
Oh, chain adjustment. Don't adjust the chain too tight. Follow the
directions in the manual, which will have it "too loose" (you think)
but long-travel suspension requires it to be that loose. I basically
follow a rule of thumb where, if I push it at the chain's center up
towards the swingarm and it comes to within 1/4"-1/8" of the swingarm,
it's fine. Less slack than that (can't push it that close), it's too
tight. But the first couple of times, measure it according to "the
book", until you get the right "feel" for where the chain's supposed
to be.
