bike chain

I have a 7720 tinsel strength chain.  Is it strong enough for my 1986 FJ1200 for normal use of bike? :wacko3:

Best that I know, tinsel is ideal for Christmas trees only. I wouldn't think it would propel a bike very well.

Hey vettman, welcome, don't let Mike put you off, first impressions and all....
A 530 o ring chain with a tensile strength of 7720 would be IMO a bit low for normal duty on FJ's. I would not recommend it.
But....seeing as though you already have it, give it a try and keep a eye on the amount of chain stretch you get.
We have found that FJ's are hard on chains. The extra $$ you spend on a premium chain seems to be worth it over the long haul.
DID ZVM-X chains have a tensile strength of around 10,600 and the monster EK ZZZ of around 11,000.

Cheers!

I repeatedly broke a chain that was rated at 9100lbs, on an FJ, during normal use.

I then put my big boy panties on and bought a good chain.  Not only did it not snap and hole the cases (again!), but it didn't stretch and require adjustment so often.  I will suggest getting a plated (chrome, gold, whatever strikes your fancy) because the sideplates will resist rust a bit better if you get behind on the cleaning, doubly so if you ride in rain and such.

An EK ZZZ is rated at 9400lbs.  The chain I went to was actually rated lower than the "9100lb" one that I broke, and there doesn't appear to be a stanardized testing routine.  So ignore the rated strength, and get something with a good reputation.  EK, RK, Regina, and DID all seem to be liked pretty well.  I personally won't ever use anything but a EK or RK, but go with your own personal preference.

FWIW
I broke a regina gold chain on my KX500 on the ice, this chain had less than 10 gallons of gas on it.   :mad:
Of course it broke the cases.  :bad:
Now I run the best DID I can get.  :yahoo:
Thats what was on it before my friends shamed me into replacing my 13 year old never failled chain. :dash2:
And when I wear the FJs chain out, it will to get a DID unless someone has bad things to say about them.

Andy, re: EK ZZZ; was there some sort of third party testing which came up with that number? 9400 is low according to the mfgr's specs:

agree with andy B. RK chains. never had an issue with them . bit pricey but cheaper then replacing engincases/sidecovers/limbs

las1200

knowing nothing about the chain on my fj I wonder how can identify it, brand and specs?

RichBaker

Most chains have some sort of markings on the sideplates.... take a look and let us know.

QuoteI broke a regina gold chain

FWIW  I abused the shit out of a Regina Gold 530, far beyond what I expected of it.  Lots of power, heavy rider, sticky tire, etc.  The chain was still tight and showed no wear or stretch when I sold the bike.  One front and two rear sprockets, same chain.

I have never really bought in to the hypothesis of new chain/sprocket at the same time.  Too many variables, lots of folklore.

Pat, spec came from here but the idea was that frankly, it doesn't matter what it's rated at, until they come up with a standardized way of measuring or an independent test for them.  It's a little like tire size, they all vary a bit despite their rated numbers.

Good chains > cheap chains.  And they don't seem to go in the same category, ever.  Sadly.

Can't speak for any other brand than DID - but my ZVM has broke thru' 10K without needing any adjustment,and that's a fact... but I do have my home-made super chain oiler to keep it happy.

WRONG!


obviously a misprint as that ZZZ chain is rated at 11,000 Lbs.


KOokaloo!
