Topic: Primary Chains

[mick7504]

Is there any advantage or disadvantage by staggering/offsetting the primary chain links?
I've always run the links in sequence with each other without any known issues (except the characteristic noise) and saw on Axl's site he mentions to offset them by 1 tooth.
Got the curiosity going now.

my best educated guess from working with machinery chains is that it distributes the loads more evenly and helps reduce the chance of breakage

i would guess the same.  in case one chain somehow develops a crack or spot for failure, then the other chain could ideally carry the load a little longer.  just my educated guess as well

I can't remember, is the stock set up link to link? I think so.

Can't see where it would matter, but my opinion is less than educated.   

Would like to hear more as i am near that point with my project.

I will guarantee you this. If one chain breaks the other is gone... only milliseconds after the first.   They go when the pair of chains tries to jump the sprockets on deceleration. NOT ON acceleration.   If you every break a set of chains look at the sprocket teeth on the crank and the clutch hub drive sprocket. I bet you find very SHARP teeth on either or both.

Also, they always come out the top.

Speaking of over 6-7 chain failures experienced.

 Me too. 

 I would imagine that with the chains both lined up, the "force" would be transmitted through the heavier inner plates of the chains and then the lighter outer links of both of the chains. Having the lighter links lined up "may" put a weak spot in the chain.
 With the chains staggered, the strength of the chain would be more equal with 1 chain being on the lighter outer links when the other chain is on the heavier inner links and on and on.
 I'm not a scientist, but it makes sense to me.

I am certain that they are always setup link to link as the stock configuration and that is how I have always done it without thinking twice about it. (Old dogs, old habits!!)
I had a look through some old photos and each one shows the chains setup link to link. (ie. not offset.)
I think that the offset idea has a lot of merit.

I think I will do mine that way.

And if it blows up its your fault!  JK

We can fix it but you'll have to come for a visit down under.
