WR 250 R Chain Slider

[sleddog]

Jim, Dave or anyone else

I've bought my WR with 9k, now I've got 17k on it. I replaced the slider at about 12k just cause it was getting close & I replaced the chain.  It went another 3k & was just wore through. The next one lasted 500 miles. I put a new one on & rode about 30 miles & it's damn near wore through. Gearing has always been 13/49 Chain & sprockets are good.

Any ideas???

Lots of theories on why some WRR's wear out chain sliders quickly... I don't know the definitive answer. I have to replace my chain slider every 5-8k miles. Not great mileage but I can live with it. I'm running 13/47 and x-ring chain.

Yamaha issued a technical bulletin on chain adjustment for WRR but it only applies to stock sprockets (13/43). I set the chain slack as shown in this article. Enjoy the photos...

Thanks guys for the feedback.....

Jim, the link must be broke! I don't see anything about chain adjustment

Aside from the other issues that this How-To article raises. Is it true that the shock has to come out to adjust the slack properly?

No, usually you can just unbolt the bottom of the shock, or some guys use a ratchet strap around the seat and leave the shock on. I think they removed the shock and subframe just so they could take more pictures of the girl.
