Is it time to replace your chain and sprockets?

What condition are your chain and sprockets in? If you pull your clutch in while coasting does your chain sound excessively noisy?
Often a good clean and lube can transform your sprockets and chain, I clean mine once a week religiously and douse in ptfe. Stripping and cleaning your chain regularly certainly prolongs it’s life. It’s important not to spray over old lube, as this has picked up lots of road dust, and is simply acting like a fine rubbing compound.
The jury is still out on the best cleaning agent/lube to use, there are any number of threads dedicated to that :wink:
A badly adjusted chain is often the cause of problems. Too slack and it’s at risk of leaving the sprocket and doing some expensive damage, too tight and you are putting excessive stress on your output shaft and running the risk of the chain snapping. As a very rough guide to chain tension, with the bike on it’s side stand, you should be able to move the lower portion of the chain up and down about an inch. Refer to your owners manual for precise values.

However, if after lubing the chain is still noisy, becomes noisy quite soon after treating it, or has a stubborn stiff link that clanks periodically over the front sprocket, it might be time to consider a new chain and sprocket set.
There are various ways to tell, initially a visual check is a good start. The front sprocket wears fastest, so removing the sprocket guard periodically and checking it is never a bad idea. You are looking for a symmetrical sprocket, this picture demonstrates the difference between a worn and new front sprocket

The back sprocket is prone to wear too, especially if a prior owner has skimped on cost by simply replacing the front.

Chains tend to stretch over time, some bikes have a stretch indicator on the chain adjusters that act as a guide. Failing that, your owners manual contains details on chain stretch. This usually involves measuring the chain across a number of links, then comparing it to the tolerances given in the manual.
A chain stretched beyond the recommended tolerance is dangerous. It’s not common for a stretched chain to snap, but it’s certainly more likely.
Occasionally a single link will become stiff, ticking every time it passes the front sprocket. Cleaning and lubing masks the problem for a while, but in my experience it’s usually a sign that the chain is on it’s way out.

If all that checks out, the noise might be the result of a worn rubbing strip. They lie along the swing arm under the chain, preventing the chain from wearing the metal beneath.
They don’t last for ever, and when they wear through, you risk damaging your swing arm and chain.

I’m supplying and fitting quality DID chain and JT sprocket sets for a wide variety of bikes.
If you live in North London £150 inclusive.
Destinations further afield will incur a small extra charge to cover my traveling time.

PM for details.

Gavin? :smiley:

^^ beat me too it! :smiley:

is that 150 including parts :Whistling:

Yes :slight_smile:

Wow £150 for a chain and sprocket set. I will have one for the 1199 at that price:Wow:

Having just priced that up :w00t:, I may need to add a disclaimer to my original offer; Italian exotica excluded. Besides, I don’t carry the gold flake lube you use :wink:

And me! :w00t:

You didn’t mention one other useful indicator…

mileage, my SV650 chain has done 18,000 miles.

And yes it’s got a few seized links, makes a racket and now needs
adjusting far too often, i.e. every few hundred miles.

So I’m looking at replacing it, might get an X ring chain and I
am considering an anodised alloy rear sproket and Nickel Chrome
Molybdenum alloy steel front.

What are you offering for £150 ?

Generally speaking: A DID x-ring rivet link chain in gold or silver, chromoly front sprocket, carbon steel rear sprocket. They usually come with a 12k/12 month warranty.

I’ve just had a conversation with a gentleman who was keen to see the breakdown of my ‘150 + fuel’ chain and sprocket offer.
To clarify:
There is no accurate breakdown. The cost of the kit varies between £80 and £120. The labour largely depends on seized nuts, breaking chain splitter components, the amount of crud built up, how much skin your aftermarket pegs take off my knuckles…
Rather than price each job individually, I’ve opted for £150, which I reckon is a fair price. If the bloke round the corner from you does it for less, then give him the work!

Sometimes I win, sometimes I’m much closer to breaking even, but I’m confident that on average I can make a profit that justifies my time and expertise.

Your price is more than fair when mines up for renew you be the first person I contact

because someone else can do it cheaper doesn’t mean they can be as good or better

(I Still owe you piccys of my fairing ill try to sort it out this weekend)

i would take you up on that offer for my 650 but unfortunately my 650 doesn’t have a chain and sprockets lol

Scorch, can you weld plastic bumpers on cars or vans ?

I was wondering when they’d arrive :wink:

Never tried mate. Is it a big job?

3 or 4 inch crack, bloody pigeons

oh yes I wanna a gold chain and gold rear sprocket for my R1 :slight_smile:

not because its worn out, but because its gold :wink:

pm’d you :wink:

Scorch replaced mine on Saturday

Bike feels so smooth now!
