Cg125 Chain :|

[Belgarion]

Well, after the advice given by you guys, I found the problem was the chain itself - I had already adjusted tension,and when I was testing alignment, I discovered a couple of links have seized. I tried some WD40 and relubing, and it seemed to help - until last night when the chain came off the rear sprocket. That wasn't fun - pushing it a mile or so was the last thing I wanted to do

I've re-tightened the chain for now - it works, but it's not exactly ideal. I would just leave it and not use it, but I have no real choice but to ride it as I need it to get to work.

I've been quoted between £40 and £65 to get a new one sorted and replaced.

I'd imagine I could probably do it myself - I checked out the various threads on it, and I think I can manage it.

Couple of questions tho:

Is a CG chain attachable without needing any specialised tools?
Are there any pitfalls I should be aware of that might end up making things worse?

Ta guys

i find all you need to fit a new chain on a cg size machine is a small flat head screw driver and a pair of long nose plyers, the small link size of the 428 pitch makes it a very easy job, i got my last chain from hien gerike for £16 they dont last long but i get 6 months out of one,

for £40 or so you can get an o ring chain which will last alot longer but i never had a problem with either,

if you get a cheap chain though get some good lube and do it regulaly or it will go alot quicker,

the split links are usualy suplyed with the chain so you shouldent have any problems

stinkwheel Well I just had my hands up a pigs fanny. Which makes your concerns pale into insignificance.

It is a doddle buddy. honestly. you wont even need a radio to listen to whilst you do it as its a quick and easy job.

Firstly, you want to undo wheel bolts slightly so that you can then slide wheel forward so that the new chain will fit using the chain tensioners.

Unclip the old chain at the clippy bit that looks like a U (forgotten what its called) with long nose pliers. Attach new chain to the old one and pull the old chain through thus will pull new chain into place (this till save you time trying to get the chain round the front sprocket as its a pain if you dont attach it), once pulled chain through, connect new chain up with the new clippy bit. A quicker way to remove old chain if its too corroded to remove the U clip thing is an angle grinder and then pulling new chain through but i shall let you decide how you would like to carry out your work.

Make sure you get the clip bit in the right direction (there will be a small diagram on the packaging showing which direction the clip should face when at the top of rear sprocket). it is essential that you do it as stated on the diagram. not following instructions leads to accidents and thats something no-one wants.

now you need to tighten the chain tensioners to the new correct position then tighten the wheel bolts back up.

Lube the new chain, wipe of excess lube and your good to go.

I done my chain not so long ago. i own a cbr 125 and imagine your chain will be similar to mines, shouldnt cost more that £30 for a fairly decent one.

Good luck

I've heard you should always change your sprockets when fitting a new chain otherwise the chain and sprockets won't match as evenly and so wear out a lot quicker...

3 words dude.. Fvck. Yes.

[nightshaddow]

for sure the 40 pound one will be better quality and last longer but you wont have any major issues with the 15 pound ones i have bought them many times when funds are low and as faraz said look after it good lube and correct adjustment
