If the chain is in good condition, why not just pull a link or three rather than replacing the whole chain?

If ya can get the chain off. Hold it off the ground and swing it from side to side. Any more than 2 or 3 inches of "swing" the chain is shot. 10,000 miles (if that) is usually my max. If you replace the chain you should also replace both sprockets. I usually don't though. About 2 or 3 chains per sprocket. The stretch is caused by every links shaft and hole wearing. That is where the side play comes from. as the chain wears it "stretches" and the links get sloppy on the sprockets causing even more wear, specially to the sprockets. If you change your chain more often the sprockets will last longer.

A few ccs short of a full litre.

Sepias

If you are suicidal, go ahead and do that.

Hmm I guess I was off on that one Is it ever safe to remove links? Ive been told that pulling links is a good thing to tighten the chain... I guess I was told wrong?

As said earlier, the chain stretches because the holes in the side plate deform around the pins. If you pull links out, you deform the holes even more, and sooner or later one of them will snap out.
Now consider that the considerably horsepower of the engine is transfered enterly thru the chain. If the chain snaps it will fling off at a very high rate of speed, and should it hit your leg, its going to cause some very serious injuries. I'd rather armor all my tires than pull links out of the chain.



To anyone else reading this: DO NOT ARMOR ALL YOUR TIRES.

SepiasSoul it is not advisable to chop off a link or two of a woren chain with modern bike as of mid-80s & on.


Also another small test Meat is have the bike in neutral & if you can pull some of the chain away from the rear part of the rear sprocket like 1/2 way up the teeth then YES time to put on a new chain. Sprockets might be advisable. Some let chains go till 2nd change though in honesty it is best to do each time.

Chain/sprockets

If a worn out chain will prematurely wear out sprockets, does it stand to reason that worn out sprockets will prematurely wear out a new chain? I would think so, but I don't know for sure.

I wouldn't want to put a brand new $100+ chain on a set of old sprockets, especially when a new set of sprockets only costs about $45. I always replace chain and sprockets together. Besides, why wait for another 10,000+ miles for a gearing change you want to do? Do it now!
