Chain Tension

How tight do you run your chain? The specification seems very
tight to me.

I have mine about 3/4 inch to the slide guard. The manual says
1.8 inches, but that didn't look right to me. I have yet to
talk to a KTM expert about it.

I run mine fairly tight. The older the chain the quicker it
starts slopping around. If I went back to more offroad riding
I'd probably loosen it. But as for now doing the whole street
thing predominantly, I'll stay with a tight chain.

Here's my $.02
Ideally what you want to do is check the tension with the
counter-shaft, swing-arm pivot bolt and axle in syzygy (i.e. a
straight line). In this position you should have a small amount
of play 1/2" or so. This will be the point at which your chain
will be the tightest. This is the point that a tight chain will
cause problems.
When I was changing the spring on my rear KLR shock I lined up
the swing-arm while I had the shock out. I then adjusted the
chain to the tension I was ok with. After putting the bike back
together and setting the sag I then checked the chain tension on
the side stand as per the manual. It was definitely looser than
recommended.
I'm not saying this will be the case with the 690 but until
someone checks it at syzygy I will be running mine a bit loose.
I have a few parts coming in this week so if it doesn't look to
hard I'll do it and let you guys know how it turns out.

Hi Guys,
It's always interesting deciphering European manuals, isn't it?
My 2 cents, at 30 mm back from underside chain guard, push chain
up and it should almost touch (.2"?) the swing arm. On a new
chain, it's less important to rotate the rear wheel and check
multiple locations, but you might as well develop good habits
from the start.
My issue is that the factory chain has no master link. That's
got to be changed.

Aloha 690 Enduro Forum, this is my first post here:
I've got a fairly new Husky 701E and now after lowering it with
a Koubalink(-1.25"), chopping the sidestand(-2.5") and setting
up a heavier shock spring(110) Of course, now I need to tension
the chain. I too, thought the factory spec. (.20") was very,
very tight. I think that they could only be imagining a bike in
a pristine showroom, delivery state. The assumption that your
counter balancer, swingarm and rear axle will be in alignment
whilst the bike sits on its sidestand could only be accurate on
a new, unmodified bike. Any changes to preload,tires, sidestand,
spring or cargo would throw their basic assumptions out the
window.
[list]
[li] The danger in operating your bike with too much tension is
that you destroy the chain, sprockets and the counter balancer
bearings...perhaps more. The cost to repair this would be
$500-$5000.
The danger in operating your chain too loose, assuming not
ridiculously loose, is that you prematurely wear out some
plastic guards that were meant to be worn out. Cost
$30-$100[/li]
[li][/li]
[/list]
I intend to reestablish the correct tension as follows. Assuming
that KTM's idea behind the .20" slack was that the balancer,
swing arm and axle would all be in a direct line; I will use a
ratchet strap and make crank it until those elements are
directly aligned. Then I'll adjust the chain as directed by the
manual. After that I'll release the strap resting on the side
stand and I'll measure the chain deflection at the prescribed
point with my caliper. This new number will become my setting
for my bike as it is actually modified, equipped and adjusted.
I am new in here and I would like to hear what you old timers
think about this logic. Mahalo

Pasomonte, check out the Youtube channel for Slavens Racing. He
has a good video on chain tension. If you are going to change
your shock spring, you can take care of both at the same time.
