How many miles on a pair of sprockets and a chain?

[MiniMadMan50]

Just wondering about how much life you guys get/gpt out of your stock WR426/450 chain and sprockets ? . I think mine are just about done for.

I only have 600 miles and adjusted my chain slightly once. The sprockets look almost new still.

Smoke ?

Really? Damn. I'm almost up to 900 miles, and I think the sprockets look ok, but there is a violent rattle anytime under acceleration. I posted a question about it a month or two ago. I don't know what to do ? I have a big ride coming up next weekend, and I really want to get rid of this rattle..

If it rattles more at real low RPM, then your chain might be too loose. I think there's a pic of a worn sprocket in the manual. /\ vs )\ on teeth. I've got 1500 km and have tightened it twice. Chain is more worn then the sprocket.

I have 5000 miles on original chain and 15/50 sprockets and it looks like they're good for another few thousand miles. I use Maxima synthetic chain lube... The chain stretch limit is 15 cms for 10 links.

The swingarm slider tends to slap on the swingarm, wearing it out and causing a loud rattle, especially at lower RPM's...Check out Motoman 393's "Fixing the YZ's faulty swingarm slider" in 'Tech Articles'- 'Misc:'.

Or search this forum for "Swingarm" or "Chain Slider" and you will find lots of info on the topic.

I bet you notice the rattle most on pavement, right?

Minimad your drive train wear will vary with the type of riding you do and the conditions you ride it. Also you have to figure maintaince, ie adjustment and lube. If you ride in mud, dust,sand, large hill climbs, or a host of other issues.

I probably didn't get more than 300-400 miles on my stock chain. Now I changed it out before it got really bad because when they start to wear they will wear on your sprokets much quicker too.

Like the others said your rattle maybe the chain slider and your other items may still be in spec.

That is amazing wear & mileage to squeeze out of any chain and sprocket combo. ? Ever since I started riding big bore 4T bikes, I have not had a whole lot of luck and durability from either my chain or sprockets. What kind of riding conditions you subject your chain & sprocket's to plays a large role in determining their lifespan. Where I usually ride, there's an abundance of mud and deep puddles in the spring and fall. Prime conditions for maximum wear and tear. Moreover, correct chain tension and maintenance will also determine how long your sprocket's will last, and vice versa. From my personal experience, I have not been able to ride an entire season (for me,usually about 4000 kms.) without wearing out my sprocket's and chain. If you own and ride your bike long enough, it's something that eventually you will have to replace.

My original chain and sprockets went 3800 miles at replacement.

My riding is dual sport use with almost no mud riding. Some sand riding.

Your mileage may vary.

Just wanted to let you guys know, I adjusted the chain slack, to the maximum tightness level (about 1.6" play), and I also shoved something underneath the chain slider. Sounds smooth as silk now ? Thanks a lot!

To rid that rattle, add some RTV (room temperature vulcanizing) under the slider, this will vulcanize the slider to the swingarm and remove any rattling. Mine did the same deal, I replaced all sliders and found I had some wear on my swingarm. Now the slider and arm are one piece. It does come apart if you need to replace the slider again. I always replace sprockets and chains with new about every 3 riding seasons. I always use steel sprockets for durability, I'm not racing.

Hey Chad, going to the tighter spec on the adjustment might not be the best thing. I run mine at 2" of slack and checked it when I had my shock out to change the spring. I still had good slack with the suspension at its lowest point. Our chains will make noise because of the range they have to cover for suspension movement, getting them to tight will cause premature wear and/or failure of the output shaft bearing. Also make sure the rear sprocket is inline with the chain, this can kill a chain and sprocket in short time.

March '04 will be two years on my bike with 14 desert races this season (total around 1000 miles) and countless miles of play and practice. The stock chain and sprockets in still good condition.

Over 1000 miles and still going. I am about half way through my adjuster. And I don't exactly ride my bike like a ten year old girl either.
