bike chain space between sprocket and chain

[stranger12]

Hi All,
While adjusting my chain, I took a picture of my chain which shows that you can almost stick a screw drive between the sprocket and the chain despite the chain having only 20 to 25 mm of play
This is the case on my 125 but not on my bigger bike

Is that normal ?
Here is a pic for your information

I wouldn't have it that loose. Have you checked the slack all the way across the chain by rotating the rear wheel and checking the tension again say 1/6th the way round?

Basically, check tension everywhere.

It's normal when the chain/sprocket is worn

Before chain wear stickers started appearing on some bikes and weighting the chain and measuring a specific number of links became De rigeur,
the old rule of thumb was that if a pencil could fit into the gap it was time for replacement.

i should say the chain had done 12k and i took 2 or think 3 links out so could get it tight again

it was streched all the way before taking links out

No, don't remove links just accommodate stretching. New chain time (and possibly sprockets).

so you think that the chain links are now bigger than it was before(stretched) and thus not fitting on the sprocket ?

if that is the case, i will change them all ( sprocket and chain).
why do you think that the chain will snap ? it may come off but wouldn't snap i think

one thing , i guess it will snap due to the wear on the pin hols becoming so big so one link is just going to brake thus come off , am it correct ?

12k miles, slack on the sprockets, definately time for it to be changed out, sprockets too.

You mad bro, don't think of the kitten but think of your chain strain and the inevitable pain game if it snaps

Time to replace everything !

This is so dangerous it's unbelievable, I'm surprised the chain hasn't already ripped your leg to shreds from snapping.

Just thought I post back.
I did change the whole set and now all seems good and happy .
Although the new chain had some lubricant which think was oil on it but again I did apply lubricant to it

thanks all for your help

would the chain stretch caused any power loss?
