Yeah, what they all said. If it has tight and lose spots, it's whacked. Probably an adjustment issue and damaged O-rings. Most people over tighten the chain cuz it "sounds" right, but when you sit on it or the bike jacks up and down from riding topography, it can stretch it out. Also, if you've cleaned it with anything like gasoline or WD40, that'll damage the rubber O-rings. Kerosene is good cuz it doesn't damage rubber. Then get the chain warm by spinning it on the stand or riding for a couple of miles and slap some good quality (PJ1 Blue, etc.) chain lube on it. Don't be stingy and let it soak into the side plates and top and bottom of the chain. Then wipe off excess and run it a little more to soak it in. I've had problems with EK chains for some reason. I've gotten better wear from RK and DID. I mostly race but they seem to do the trick. Also make sure you change your chain and sprockets together. Line up the chain looking down the back sprocket to the front and the chain should be straight but not taught. The side plates should be even (use a ruler to make sure they are straight). And see if the teeth of the sprocket are hitting in the middle of the links. Be sure to tighten to 1/2 inch slack in the middle of the lower chain with your weight on it. That's about it...
