I just went through the same problem at 46,000 km on the original chain and sprokets. Replacing the chain and sprokets solved the problems. The bike runs as new. Prior to replacing this gear I carried out all the tests mentioned in this thread. However, I did have the dealer do the install parts (Suzuki kit) $187 and 1.5 hour of labour at $80/ hr.

A sure fired indication that the chain is "done" is that it will appear rusty brown in color. This the internal roller bearing grease in the chain coming out.

Make sure you do not smash the rivets to tight together on the master link.

Manage the unavoidable.
Avoid the unmanageable.

By looking at the 2 pictures the chain is way too dry. Lube it at every fill up.

I rode on the same, original chain for almost 30K miles. Yep, it was stretched like crazy, probably dangerously so.

How could I tell something was wrong? It was making noise---a lot of weird, slappy, clunky noises---and only when the bike was moving (not sitting in neutral idling).

So...this may not be very scientific...but it's worth remembering: if you ever hear anything from your chain other than a smooth "whirr," something's wrong!

So how long are chains and sprockets supposed to last?

When did you replace your chain?
