So i keep tightening my chain using the adjusters, and it seems to immediately get slack again? The chain is pretty new, only done 3-400 miles?
is the chain stretching? or is something else going on?

Re: Slack Chain
Possibly a stupid question but are you sure the adjusters are locked out?
New chains do stretch as they bed in and also as the rollers wear over time, some makes more than others, but it should only be a few mm at a time.

Re: Slack Chain
Yes I checked that and both sides are still locked out, I’ve taken it back two notches now, I may have to take another link out at this rate!
What happens to the rollers?
Thanks

Re: Slack Chain
The rollers are the part of the chain in contact with the sprocket so its the part of the chain that wears. As the rollers and sprocket teeth wear the chain gets slack... but again this should not be noticeable after 1 ride as it takes place over the life of the chain.
Also remember that you have to remove links in pairs due to the way the chain is constructed. I don't know your chain but taking out 2 links is extreme and will probably mean your chain is too short.
I think its down to technique... so make sure the wheel is up against the adjusters when you set them and when you tighten the spindle nut. You can do this by jamming a rag in the top part of the chain/sprocket which will pull the wheel/spindle against the adjusters. Check out YouTube for good ways of doing this.

Re: Slack Chain
Did you replace the sprockets at the same time you replaced the chain?
What chain did you buy? O/X ring or none O/X ring?

Re: Slack Chain
Dirt bikes need loads of slack, you’re not over-tightening it are you?

Re: Slack Chain
An over tight chain can cause serious problems .
In certain circumstances like a heavy landing it will break the crank casings or output shaft . My rule of thumb is 3 fingers between chain and swingarm half way up chain glide before swing arm pivot. Most chains after the initial setling down will only need minor ajustment every often.
