tight spot in chain

[cyndemgum]

Adjust slack at the tight point regardless of the slack you end up with at the loose point. Paul.

hey thanx,what if the loose point is to loose,and what do you think would cause this?cheers

Sounds to me like the bike has been standing unused for some time and a series of pins and rollers in the chain have semi-seized. Keep it well lubed and ride the bike fairly hard. Keep an eye on the slack as it is likely to increase a fair amount as the chain frees up. Hard to say without seeing the bike but at 8600 kms the chain is most likely still fine,
