If you push your chain all the way down so it is tight, then pull it up until it's tight that should be about 1 1/4" to 1 1/2". Test this half way between your sporckets

...got info Bot!

Just another bit of advice....before riding, always test the chain to make sure it's not too tight/too loose...our friend just bought a '08 YFZ450, and didn't check the quad over before he took it to a race....the chain was too loose, popped off the sprocket, broke his case, shifting shaft, and it took gears out of the motor...so, after paying for a brand new quad, he had to turn around and pay $600 in labor to get it fixed (warranty only covered parts).

I always keep about one inch of play in mine, with my weight on it, so what stoopidbot says is right, cause it cinches up a bit with weight. and the same thing happend to my buddy's KFX, the chain came off and slapped his shift sensor, so his neutral?reverse light quit working, he's lucky he had a warranty, or the chain didn't bust the case. But his is brand new and they are putting a new block on his because it was going to have to be welded. He lucked out major.

yeah I guess so.....especially compared to our friend.

But, at the same time we were like, how did you not check the chain before you raced? That's kinda your own fault...haha.

make a habit of checkin it after you wash it or while it's warming up. It needs to be in neutral and rolling back and forth. DRY will actually make them shorter or tighter! I have seen some SO tight it took 2 ppl to push it, and of course, he wanted it serviced under warranty! Well, welcome to the world of Honda heh heh. Need I say he was disappointed? LOL Keep it lubed and keep it tensioned right and you'll be OK. Just don't forget it cuz it will come back to bite you and it can get spendy when it snaps a case! OUCH!

Great advise, Icheck mine after every wash. And keep it lubed,read the labels. I use Bel-Ray and they recommend lubing the chain when it's warm.

SBot, you are absolutely right and here's proof:

my raptor is a 2001, has many miles but gets cleaned and checked after:aargh: every time. it's been seven years, my chain and sprockets look like brand NEW. My kid does not have my maintenance habits and is ready to buy a thirdset of sprockets and chain. smart guy. Hey it only takes a minute, and if you ever have to walk because of a failed chain you will know LOL.

Curious, when measuring the chain where should you measure from?

Bottom 1/2 of the chain to the top 1/2 or measure from the chain guard to either the top or bottom half of the chain.

I was checking my chains slack tonight and I tried measuring by taking a ruler and sitting it on the lower part of the chain and pushed and pulled the top, then I tried setting the ruler on the chain guard and measuring the top of the chain. the results were not that dramatically different 1/8" or so.

I was thinking, what if you measured from the chain guard and the chain guard got bent by a rock or something; that wouldn't be very accurate.

Thanks

      How do I know when to replace them? I know it should seem easy and obvious, but I'm really at a loss here. My chain, when held sideways in mid-air, bends at a curved 90 degree angle. It seems pretty loose , i.e. everything moves kinda side to side. I'm guessing thats bad, however my sprockets look better. The rear sprocket has no curved teeth, however it is showing signs of slight wear because on one side of the tooth it is slightly curved and the other side it is slightly flat. Also, the front sprocket has slightly hooked teeth, but they are still thick. If all this stuff is "slightly", can I just leave it? Also, the rear sprocket hub has a couple cm's of free play forwards and backwards on the axle. Is that bad too? The chain seems like its the worst of all, but people tell me to not just replace the chain, but also the sprockets. I have three machines and cant afford to do that. Advice?
      On my dirt bike, the chain is exactly the opposite of the one on my YFZ. It is sturdy, and nothing really moves; however it seems so "sturdy" that the chain gets kinked in some areas. Instead of replacing the chain, can I just give it a quick oil and be done with it?
