Is it measured in pounds?
-
Tensil strength refers to how much of a load can be applied before it breaks?
More or less yes. Tensile force is a stretching force. Think about fishing line because it is measured in tensile strength as well. Stronger fishing line can hold a heavier load before it breaks than a lighter line. Same applies to bike chain. The engine sprocket is like the fishing reel, the rear sprocket is the fish and the top loop of the chain is the fishing line. Under acceleration, the engine sprocket is trying to pull (tensile force) the chain from the rear sprocket to the front.

Ya, I usually end up with a 110 - 130 link chain too. 8050 is a good tensile strength chain. Hope it works out good for you.

I just asked a guy this the other day and the conclusion of my advising senior men is that sealed is the only way and check tesile strength and if you buy a gold chain it's there better level of performance ... They concluded that there is so many choices out now who can try them all??? They had me buy EK gold Xring with a tensile strength of 8050lbs it cost me around $116 for 130 links of 520 because I have a plus six swinger and a OEM is I think 92 links? I hope this helps and I almost bought the 3-D chain lol twice as much money just for cosmetics ...

lol, no problem. I've already spent the money and made lots of mistakes along the way. I hate learning this way, but it sinks in that way I guess :D
My memory is so bad I keep making stupid mistakes and usually end up farther behind than when I started. Lol

Thanks for explaining it. I really learn a lot from you guys. Thanks

Sorry, I'm sure I saw something like a d and w type o-ring chain, but there are mostly 'O' and 'X' ring chains.
The 'O' ring chain, likes its name looks like an 'o' when viewing it from the side.
The 'X' ring chain is another type of sealed chain. When viewing it from the side looks like an 'x'.
(http://i111.photobucket.com/albums/n135/rogue1970/X-ring_O-ring_zps6gfwhto5.jpg)
The idea behind the 'x' ring is that it has two smaller surfaces that contact the plates and provides less drag then the o-ring chain. I've read articles that tested the o-ring chains and while they do drag more (not very much) then a non-sealed chain when cold, once the vehicle is run for a few minutes, the chain comes up to operating temperature and it is as good as or better then the non-sealed chain.

I've never heard that you should measure the length of 21 pins. Just the chain slack/slap. I'm glad I asked. I also didn't know about the different types of sealed chains. What's the differenc between sealed o ring chains and an d, x, w?

FYI... chain stretch is a common term, but really it is your chain 'growing' The pins and bushings inside the chain itself wear and that is what makes the chain become longer.
Like I said before, just make sure to buy a good quality sealed chain (O,D,X.W,etc...) and regular maintenance will yield the longest life..... also replace the chain & sprockets as a set. Also, don't just depend on WD-40 to 'lube' your chain. WD-40 refers to Water Displacement version 40.... good for getting water out of the chain, but doesn't have lubricating oil required by chains.
Like Throttle Therapy said, just watch new chains that are installed and keep it adjusted to specs.
Measure 21 pins on the chain. It should not be > 319.4mm / 12.57"
Chain Slack - 25-30mm / 1.0 - 1.2" between sprockets
Good Luck.

Don't forget all new chains will stretch a little after a couple of heat.cycles. keep an eye on it.

As rogue 1970 said install new sprockets at the same time. I run a did atv x ring chain( i think fancy term for o ring chain) , on both my 85 lt250r and my sons 86 lt230 quadsport wraped around vortex sprockets. . I have adjusted it twice in the first 16 hours of ride time . I haven't touched it since. 40 hours on them now. We run them very hard too.
-
Oh.... don't know the specifics of the 250's.

I'm not sure if Shawn is still building these,

Run a HD case saver for a little more added protection against case breaks.
I believe his is an 85 so not sure that case saver will fit.

I've ran RK 520XSO with 8,500 Lbs tensile strength for the last 3 years.
Bfuss has ran the rocky Mountain for about the same amount of time and both seem to be good chains.
-
As for a chain, just find a quality brand like EK, DID, Regina, RK, etc... I've been happy with DID, EK and RK brands lately for my Zilla.
Remember if you are replacing your chain, you should replace both sprockets too. If you don't, your new chain will 'wear' / 'stretch' to match the condition of the sprockets quickly.

I'm wanting to buy a chain for my 85' 250. Sometime in the past my cases got broke from a chain breaking. Once I send my quad to ice racer in the future, I'm going to have him do the repairs and from then on I want the best, strongest chain to prevent it from happening again. What is a top shelf o ringed chain?
