I just got finished reading this article:

http://www.webbikeworld.com/t2/motor...hain-sprocket/

...and it led me to a few more questions:

1.) Are the parts in this list universal for any Hinckley Classic Triple? (I have a 99 Legend)

▪ Triumph Front Sprocket, 17 tooth
▪ JT 45 Tooth Rear Sprocket
▪ DID 530V Chain (*See note)
▪ Locknut for Front Spline
▪ Clutch Pushrod Seal for engine case (TR3600012-T0301)
▪ Shifter rod seal for sprocket cover (TR3600008-T0301)
▪ Side Cover Gasket (TRT1260801)
▪ Rubber chain guide
▪ Clutch Pushrod (optional but recommended) (TR1170270-T0301)

2.) I counted my links, and there were 116. Is that normal for a stock triumph chain? I counted the side plates twice, got 58 both times.

3.) My bike has about 15,500 miles on it. If this is the stock chain, could it be wearing out already? There's a good amount of slack, and the spindle nut is almost at the second to last marking.

I think my bikes had 114 links stock. But I also think the Legend is different.

Chain life depends on how well it is maintained.
Mostly just keep it clean and lightly lubed and it will last a long while. I replaced both my chains at around 18,000 miles.
I don't know how much the previous owner kept care of them.

Some folks get more miles than that out of a chain, but I think that's about average for the original.

That list is pretty complete.

There is a seal on the countershaft, under the countershaft sprocket. I always replace that one too.

And the stock rear sprocket on a Legend is 43.

43/17 = 2.5333 is stock on most of the classic triples

45/18 = 2.50 is what I used. in order to preserve the rubber chain guide.

Some folks use 43/18 = 2.3888 in order to make Highway cruising a little more relaxed. Especially on the 5 speed models.

As long as you can adjust the slack out of it, and it does not have any stiff spots, I'd run it for awhile. At least until you understand the pros and cons of changing the gearing to be different than stock.

With your chain adjusted to the correct tension, grab the chain,on the 3 o'clock postion onthe rear sprocket. Pull it. The more you can pull it from your sprocket, with correct tension, the more owrn out it is. Just becasue you can move the wheel back does not mean the chain isn't bugered.

See my post on your new bike thread, Legend chain is same a Tbird, 114 links.

About 24000 miles on TBS with stock chain. To do more wasn't recommended

Changed with EK:
http://www.ekchain.com/
About 25000 miles done. Guess can go for 10000 miles more.
I do not wheelie and take regular care of chain. For next replacement I will buy chain of same brand.

In the webbikeworld write-up, the author mentions the chain guide being flawed and wearing out long before the chain. Could I keep my existing chain guide if I keep the gearing the same? If it is going to wear down halfway through the life of my new chain, what's the benefit of replacing it?

Also, the author uses a paddock stand. My legend has a center stand, would that suffice?

I went on the DID website that was linked from the wBW article:

http://www.didchain.com/triumph.htm

In that list it says the legend is 18f 43r, with 116 links. This confirms my count, but conflicts with the Triumph Dealer, and others on the forum. I guess I'll have to open her up and check the sprocket for myself. Hopefully I will have the time/parts next week to do it.

Also found this list, saying 116 on the Legend:

I judge the chain largely by it's tight spots. As the chain wears, it will stretch unevenly. Adjust to the tight spot according to the manual, and then judge at the loosest point from there.

It is not unusual for a OEM chain to be worn out at 15k. Particularly if it has been cleaned and lubed infrequently.

Centerstand is adequate.

When the rubber block gets worn too much the chain will start rubbing on the swingarm and cause damage to it.

Remove the countershaft sprocket retaining nut before you remove the chain or rear wheel. It's a lot easier to remove it if you use an impact tool, but it can be done with a long lever.
