GS500E/S - "Knocking" noise coming from chain

[veeeffarr]

Hi,

Just pushed my bike in to park it, and noticed a knocking noise coming from around the front sprocket area.

Bike was in netrual.

Recently adjusted the chain, every time I slow down for lights etc I notice a "tearing" sort of sound, sounds like tyres (but its not)

Also when I push it forward I can hear a metallic "brushing" sound, Is this normal?

Cheers,

T

Hi Toby. Was the wheel properly balanced after adjusting the chain? It's possible that it's slightly off track, causing the chain to rub where it should be moving freely.

Hmmm! What about the condition of the chain - is it still in good nick - is there much more room for further adjustment?

The swingarm notches are a work of fiction, wouldn't rely on them.

swingarm notches are well known to be as accurate as a pea shooter

Chain is in Okish nick, about 30% along adjusters.

Some tight spots, got some latex gloves on and a lot of chain lube and freed them up.

Could be something as simple as the chain rubbing on the chainguard.

If the front sprocket has never been changed it may be that the thing has worn and the teeth are 'hooked'. Tightening up the chain might have made that more noticable.

Also... have you checked to make sure your chain is not over-tight? Always run it around when adjusting and make sure you are measuring the free-play at the tightest point. If you have a tight spot on the chain, this can also get noisy.

Finally....how often do you lube the chain? If it's dry, then it will get more noisy than a well lubricated one.

Buggeration, is there a botch I can do in the mean time? I am completely fuckerated money wise

[Blackrhythms]

Not really Toby - only take it very very handy when riding!

Well I don't want _that_ to happen

Found it today when I was trying to clean it up a little.

If a loose chain can smash through steel its going to make a mess out of your leg

Unfortunately, when it comes to chains, it's prevention not cure.

A tight spot happens when the particular pin running through the link has siezed due to lack of lubrication and wear. This stops the thing from flexing like it should.

If it's not too bad, you might get away with it for a while, but expect your chain to stretch badly. If it's bad...then you get something like the picture above..... The gearbox sprocket is the bit where the chain run curves the most...and what happened there is a result of the chain not following the curve it had to in order to get around the sprocket. It snags up and horrible things happen as chain and sprocket part company at speed.

Might be worth trying to scrounge a chain from a scrappy if you know a good breakers near you. Nobody buys second hand chains....so you might get a bargain to see you through until you can afford to get a proper chain to replace yours.

I've seen a DID kit for £73 on Wemoto, I think I might be able to get that.

Don't they come with a normal link and a split link? If I split the link and ride it to a garage to you think they'll crimp up the proper link for me FOC?

[EuropeanNC30R...]

Definitely not if you buy it from Wemoto

Before you buy a new chain and sprocket kit get the old chain to the tightest point then sit on the bike and get a friend/neighbour/goose/ferret? to check that the chain isnt too tight.

Reason is...........I had a KLR600 and it had a tight spot, I adjusted to the book on the tight spot and sat on the bike. The suspesion moved that much the chain was as tight as a drum with just my weight on it.

I had a similar noise from my GS500, although this is probably similar for any bike. I removed the cover and inspected the front sprocket, found it to be a bit loose on the splines. Also had to clean out a ton of crap from around the driveshaft and sprocket, dang that rea really does collect some sh1t.
I have a manual on CD if you want it.

[veeeffarr]

Do you think the chain could be too tight? There's an inch of play when the bike is on the centrestand, should I have adjusted with my weight on it?

There's also a faint metallic grinding noise from the rear brake disc when I spin the wheel, is this normal?

Cheers,

T

(PS: Got a loobman on order, I will get a C&S kit on it ASAP but need to wait until next month!)

How hard is it to take the front sprocket cover off on this bike? Will I need a new gasket?
