chain slack

[mvk24_imp]

I have always gone to the middle of the bottom of the chain.

Put a ruler or tape measure behind it. And give it a gentle wiggle both Up & Down and make sure it falls within the margin.

If it would move 1 inch upwards from baseline, then it would also move 1 inch below baseline (downwards). And that would give you a total slack of 2 inches instead of 1 inch in 1 direction.

This is the way I learned (but it can be wrong and im open to hearing otherwise)

Ive no argument with your technique, mvk, but surely the sheer weight of the chain will mean it will move further up than down? In other words, the lower run will be bow shaped at rest.

If when you move the chain Up & Down then what is the range of movement. Is it within an inch? 1 1/2 inch? The slack would be the total sum of all movement the chain has all together on the vertical plane.


By my understanding above, only measuring the Height of travel from a baseline of where the chain is resting does not account for ALL of the vertical slack the chain has. Which in this particular instance is a vertical plane of movement both upwards and downwards.

(I think that makes sense how I wrote it)

someone with a 14 std please look (or take a pic of) at the decal on the swingarm for me. I swear I saw it with up and down but mine is hidden behind a beautiful symmetrical chrome pipe on the lh side. lol

Now that I'm explaining my thinking it's making me more confused lol.


I believe we're just saying a few ways to skin a cat but ending up with the same result. The photo on my 14ex seems to explain it. The illustration of the chain and arrows show total slack of motion up and slightly down. Not only upwards from a resting chain position.

hmmm it appears that decal shows it only measured when pushed up

I find this conversation fascinating actually. Makes me ponder,

Mwahahah we are getting different interpretations of the same photo too!

My friend, we have started yet another oil thread

well didn't mean to start that

to me that diagram shows chain at rest and chain at top of arc (when pushed up) and arrows indicated slack is what is the gap between them. How do you see it?

edit: I went out to my bike and with a flashlight and mirror could see that that is the same decal I have on mine

- I see the both an upward and downward arrow.
- The black gap in the middle of the "moving chain" is a diamond not a triangle. (Indicating downward movement from rest)
- and the lower line representing the chain definitely appears to be slightly pointed downwards indicating a pull below resting position.


At this rate I bet we end up with the same adjustment give or take a few millimeters! As long as we are measuring how much the chain moves in any direction and it falls within the safety margin then all is well. With the miles we do we'd know if it was wrong by now haha

I'm with you cause now im pondering lol

Yea I think I pondered that too in my original post (What the difference would be between using the two different methods)

The 2013-2014 service manual makes it fairly clear you measure the deflection from the resting position to the upper position. See the photo on page 3-19.
What is the best oil to use in the CB1100? Oil filter?

Maybe I shouldn’t admit this: since the mid 1960’s, I never bothered with measuring chain slack. I just push the chain up to judge its play, and adjust if needed. Like ferret, it is too much work getting up from the floor.

That's how mechanics do it

and I hear ya brother

Rick, I think you are right about the pic in the manual. I forgot I even had a FSM, it was in the bottom of a drawer in my motorcycle gear room. lol
