2001 Curvy, as the chain moves towards the gear box it passes between the spring and the heel plate, and over the top of what looks like a piece of black rubber/plastic. Washing my bike the other day and i noticed it is practically touching this and has worn into it ever so slightly, when lifting the chain you can see small grooves.

Is this normal?

Many thanks.

Yep, all my bikes have had one.

I think at the tight part of the chain there should be 20 - 30mm of movement whilst the bike is on the side stand.

Check it ;) I checked mine this weekend after thinking it looked like it had alot of play...but it was fine :cool: only 21mm

"practically touching this and has worn into it ever so slightly"

Is this the plastic piece on the swingarm?

Yes, it's there to stop the chain eating the swinging-arm. Many (most?) modern bikes do this.

No.

No problem.

It's a chain slider you're describing. It's there for the chain to slide on.

As he say's ^^^

The groves are caused by the chain when the suspension is at near full extension, as in going over a bump (the shock absorber bump and rebound) due to the swinging arm pivot point being further towards the rear of the bike than the front sprocket.

Please feel free to change it if you think it's too badly worn...

IE if you remove it and if there are groves in the swinging arm then yes Change it.
if not then leave it as it is as it's doing it's job it was designed to do.

He means "It shouldnt" concern you, The Chain slider is "doing what its there for"

(Not "It shouldnt" touch)

Thanks everyone! :)

Kinda changing the subject a bit but while we're on a similar topic, saves starting a new thread, can anyone recommend a good method of getting chain lube of my beck wheel? The chain side of the wheel is covered in it.

Also, on side stand if i move my chain with my finger, i would say there is a little bit of play in it, maybe a centimetre up and down, that about right?

Thanks.

Well I don't know what you call it in Oz, but here in the UK I find that White spirit or Paraffin gets oil off the back wheel a treat.

There should be an inch of travel in the chain (best to check on the side stand, stand on the right-side of your bike so you can put all your weight on the seat as you check it & also move the bike so you can check it at several points in the chain and always have the inch free-play at the tightest point in the chain.
