Chain contacting chain guide

I put a new chain on today -- I knew I was going to install a new chain before I put it on the road, so I never paid much attention to chain tension before.

I noticed that when unloaded (on the kickstand), at the front, the lower part of the chain rests against the lower chain guard (on the frame, where the suspension linkage is attached) and the upper part of the chain rests on the swingarm chain guard. When I sit on the bike, I reach back and wiggle the chain, and if I pull it up, it can contact the lower part of the swingarm chain guard, but obviously I don't think it touches the other guards when I'm just sitting on it.

Is this normal? Obviously this is what the chain guides are for, and on this bike the chain tension change from loaded to unloaded is *dramatic*, but I'm just worried about things wearing -- are the chain guides wear items?

My mistake, of course the sliders are wear items to an extent, but is it normal to be resting on them when the bike is unloaded?

But not when you are sitting on it.

drumstyx,
Yes.

If your chain can be 'Almost' pressed up against the rear tip of the rubber chain slider, under the swing arm, then it is correct.

If one can 'almost' press it to touch the metal swingarm, behind the rubber slider, then it is time to Adjust the slack!

This only has to be done once for a measurement.

While having someone else sitting on the bike and leveled,
adjust the chain to almost the tighter end of the tolerance.

When they get off take a new slop-distance measurement.

There's yer distance of play while adjusting it alone. To toss in
for accuracy's purpose, check the chain in more than one place by
rolling the bike a couple of feet.

Yes, drumdude, chains look loose and sagging when parked. LOL

Running the chain too tight ranks right up there in the top handful of newbie KLR mistakes....right with overtightening the oil drain plug! ....sadly it seems that this is common in many dealership shops too.

I've never seen a chain spec this loose, that's why I'm curious, and I'm sure that's why dealers and shops make the mistake.

I've also never really lived for a long time with a chain driven bike. My main bikes have always been belt/shaft.

Yep, that's exactly why; both owners and bike shop techs that are used to street bikes more than dirt bikes. The long travel suspension and chain/swingarm travel geometry mean the KLR needs to have more slack than most other bikes.
