I have an intruder 125 which I replaced the chain and sprockets about 2000 miles ago. Not having had any bikes previous to that I'm not sure what the wear on the chain should be, but when the chain was first fitted I tensioned it to just before the first notch and made sure it had the right amount of movement in it. A couple of days later I heard this clicking sound as I was riding along and found that the chain was hanging down a bit.... so I tensioned it up again.
Since fitting this new chain I've had to tighten it every few days and now I'm about half way to the last notch on the scale.
Is this normal wear for a chain? (I travel about 50+miles a day).
When I run out of notches would it be safe to remove a link from the chain or does that offset it with the sprockets? |
A well serviced half decent quality C+S kit should last quite a bit more than 15k. If yours is running a bit knackered after 2k then either your maintenance routine is less than adequate or the chain is utter crap. Removing links to rescue a stretched chain is basically a last resort to buy you a few days until your new one arrives, it is not recommended as by that point the chain will be junk and dangerous.
What brand chain is it mate?
What is your maintenance routine?
Your maintenance routine should be something like this:
Every 100 miles or so it needs to be lubed, this can be one of the hundreds of very expensive and not all that effective chain waxes, oils, dry lubes etc etc or it can be my favoured chain lube, engine oil or gear oil.
ANY engine oil will do for your chain, even stuff that has already been in your engine, I use gear oil as it flings less but essentially any new/used engine/gear oil you have lying around will be great on your chain, apply it with a paint brush to the whole chain then wipe off the excess with a rag.
Every 500 miles or so:
It needs to be cleaned, this is very frequently neglected and tbh if you are using the engine oil routine above it is not a massive deal to delay this, the constant addition and replacement of oil tends to wash a lot of the shit away. If you use an expensive chain wax or dry lube then this is vitally important as they attract grit and dirt which acts as a grinding paste wearing away at your chain.
To clean it you want to get yourself down B+Q/Homebase etc and buy some paraffin, this is sold under various names but is usually sold as outdoor lamp fuel (it will say kerosene, paraffin or parasene somewhere on the bottle), costs about £5 for 4L which is about as cheap as you are going to get for any cleaning solvent. Get a squirty bottle if you can or just use a wee bowl of paraffin, get it on a pach of chain and scrub it clean with a toothbrush, do the whole chain until it is nice and clean and let it dry.
Then oil it up as described above.
I would expect a chain maintained like that to last a very long time  .

I have about 9 litres of used oil sitting in the garage now (free to a good home  )
Every couple of days I would give the chain a damn good rubbing with oil and toothbrush then spray some chain lube over that.
Maybe I shouldn't buy a chain and sprocket set from ebay then (although I'm positive it was from wemoto) |

What make was your chain. There's a really poor one branded 'heavy duty' which has the same tensile strength as chewing gum.

It's junk. Scrap it and get a grade 5 chain. It'll cost twice as much but last ten times as long.
