Chain slider and rear sprocket

[dropman]

I have 2004 TA and it seems that chain slider is worn out. Is it possible that this is because my TA has rear sprocket with 43 tooth? Or there is something wrong with rear suspension preload? Chain tension seems to be ok.
I have this bike only for two weeks and want to sort this out...

With a much smaller rear sprocket - 43 teeth as against 48 - then this could well be the cause of your chain slider wearing out.

Should be easy enough to replace though.

David Silver Spares want £19.73 or €22.86 (without postage) for a new one. Part number 52170-MCB-610.

sounds like the bike has had a badly adjusted chain for and extended period too,why 43 tooth was it on it when you got it?

Sorry, my mistake. It was old oil with dirt on sliders... Thats why it looked like worn out. I cleaned it out and it looks not so bad now.

43 tooth was on the bike when I got it. Previous owner said that to fit that sprocked he shortened chain.
I want 48 tooth back, but that meens that I should buy new chain, right? I also cant find soft link on that chain (its DID). So it means that I will need to take swingarm off?

You don't need to take off the swingarm. Any link can be cut. If you are replacing the chain and rear sprocket, replace the front sprocket too otherwise you risk damaging your new chain.

According to odometer, its only 10000km, so maybe front sprocket is still good enough? It is only rusty, and I cant see any major wear on it.

I suppose it depends. On a very well maintained chainset it's still a quarter worn and even a small amount of wear can accelerate wear to the chain. On a badly maintained set it could be three quarters worn. The front sprocket wears quicker than the rear because of the smaller size; some users change it half way through the life of the chain and rear sprocket.
If I was you I'd get a new one for the relatively small cost.

If it is rusty then Change it. £20.00 for a Sprocket is nothing compared to the cost of early replacement of the complete system later on when the whole lot wears out.

Also remember, if you are going up to a 48t rear from a 43t and if you want to keep the gearing the same, you will need to go up 1 or 2 teeth on the front sprocket.
