Drive Chain Question 250r

[Samjp22]

Looking to upgrade my chain to an o-ringed one. Whats the standard size for a 1985 atc 250r chain? Can't seem to find specs on it from servicehonda.com and ebay varies from 520x84 to 520x96.

[Mr. Clean]

520x96 is what I see for 1985 ATC 250r.

Spend the bucks on a D.I.D. you'll be glad you did.

Exactly what I'm looking at, the chain that's on there now is pretty stretched, the PO had the chain so sloppy when I first got it, had to cut three links outta it to make it work lol

Yeah good luck with the O-ring master link if you get one. I don't understand why, but I've yet to find an O-ring master link that actually goes together the way it should. I've tried D.I.D., RK, no name... I always end up having to grind, omit O-rings, and force things together, usually destroying things in the process. My last D.I.D. I got for the XR a couple months ago and ruined a brand new chain installing the O-ring master link before the thing had ever even been on a chain wheel. I'd like to write D.I.D. someday and see them install one of their own O-ring master links properly. They don't fricken work!

LOL!!! I've been able to do it a few times using my chain-braker to pull them together, but I've f****ed up a bunch of clips too. Now I just use rivet style masters. Prefer those anyway, but then you can't play with gearing.

I have parts to make up about a half dozen D.I.D. links, all I'm missing is clips, any idea where to buy just a D.I.D. clip?

EDIT: Just had a thought. I wonder if you left the chain-braker on the master-link overnight if the O-rings would stay compressed long enough to get the clip on?

[Samjp22]

Ill let you know my results and if I get it together nicely ill gladly take a video! lol Just typed D.I.D clips on ebay and lots came up, pretty cheap but shipping is ridiculous for me anyways

Yea, but the whole link is for sale. In theory we're supposed to replace the clips each time we remove it, but not the link as it's already worn in with the rest of the chain, so you end up with a bunch of incomplete master links.

I hope you're changing your sprockets too. Use a steel rear if you want it to last.

I have had good luck using channel locks to squeeze the master link down enough to get the clip on. Has worked well for me. It takes a combination of squeezing outside edges and middle to get it from my experience.

[Samjp22]

yeah a steel sprocket is on the list as well, PO put a renthal one on and its already pretty worn down

Yeah, but no. I've installed plenty of master links over the years. The last two took a C-clamp and an angle grinder to get them together.

we use pro taper chains. They always work great and have the strongest tinsel strength we have found so far. The 428 (size we use) is the only one with 5700 brake capacity. All others are less. So if you want a good one, they are one of the best around. not the cheapest, but in my mind the best.

Get this, DID 520 VT2 Narrow Enduro Racing X-Ring Chain. Narrower that o-ring chains that seems to always rub the cases. The narrow x ring is the same width as a standard chain. I love mine, best chain I've ever used hands down and won't go back to o-ringed chains. They almost have no stretch and last a long time.

Yep, o-ring master links are difficult to install, while x-rings are slightly easier, yet still difficult. If you're trying to install them in the cold of winter, it'll be damn near impossible, unless you heat up your o or x-rings. Try heating them up in some hot water next time, to get them nice and pliable. It makes them so much easier squish down.
