charliechitlins Posted January 19, 2004 Report Share Posted January 19, 2004 SD... I'm not really sure what you're trying to show me, there. I don't see how that shows me half a tooth. Here's how you check if your chain is whipped: Look at your sprocket like it's a clock and find 3 o'clock. If you only have digital clocks, trace a line along the swingarm until you cross the chain. Grab the chain right there, and pull towards the back of the bike as hard as you can. Check how much sprocket tooth you expose right where you're pulling.

brucej Posted January 20, 2004 Report Share Posted January 20, 2004 (edited) SD, I'd have to say your chain looks like it's done its' duty, time for a new one. Sprockets too. If you use Charlie's test method it will be more obvious, but even without it you can see the wear in the picture. You see how there is a gap between the chain pins and the bottom of the 'valleys' between the sprocket teeth? This means there is a lot of wear on it, it no longer fits the sprocket. If you look at the sprocket teeth closely, you will see that they are starting to hook over. The worn chain has caused this. It also looks like there is a lot of wear on the sides of the sprocket teeth, although it's hard to tell how severe it is in the picture, if it's just the anodizing worn off it's not a big deal. It would be caused by a misaligned sprocket. This would be a good time to check the alignment of the chain tensioner, too, that might be what's causing the wear on the side plates of your chain. When you adjust your chain, are the adjustment cams tight against their stops when you are done? They should be. If they're not, then that's why your chain keeps loosening off. It could also cause the alignment problems. Basically, you need to get a new chain and sprockets as soon as you can, and check your tensioner and sprocket alignment carefully when you put them on. You can probably run what you have a little longer (like if it's a day or two till you can get the new ones) if you take a link out of the chain, to get it back to where your adjusters are useful again. Hope this helps! Edited January 21, 2004 by brucej Quote Link to comment Share on other sites More sharing options...

dmx84 Posted January 22, 2004 Report Share Posted January 22, 2004 (edited) Dude, your slack adjustors are all the way out! You need more than a chain you need new sprockets! You need to watch out for stuff like that. Like charliechitlins said, grab the chain at the back of the sprocket (3 o Edited January 22, 2004 by DMX84 Quote Link to comment Share on other sites More sharing options...
