Sheldon Brown, the great Guru of bicycle mechanics, has some interesting observations about chain "stretch"

http://www.sheldonbrown.com/chains.html

Cyclists often speak of chain "stretch", as if the side plates of an old chain were pulled out of shape by the repeated stresses of pedaling. This is not actually how chains elongate. The major cause of chain "stretch" is wearing away of the metal where the rivet rotates inside of the bushing (or the "bushing" part of the inside plate) as the chain links flex and straighten as the chain goes onto and off of the sprockets. If you take apart an old, worn out chain, you can easily see the little notches worn into the sides of the rivets by the inside edges of the bushings.
=====================

Now the Suzuki uses a "Hy-Vo" type chain and there's some interesting stuff here about their wear:

Seems the Suzuki chain is is a weak link (pun intended) in the design!

I think that a chain is a chain....
Even if it is a stretched chain,
or if it is an old chain.
Even if it is a broken chain,
or if it is a cold chain.
Even if it is a tire chain,
or if it is a gold chain.
But not when it is a cam chain.

How do you rock them?

undo the nut as described (lefty) pull the gear as far of the splines as you can, gear will now be at an angle rock the clutch easing the gear out at the same time,

like i said its fiddly and doesn't always come straight off but with patience it will, greg I'm sure with your knowledge you'll be slipping it off in seconds once you have the feal.

I guess that it's the "rocking the clutch" that's missing me. Is that the same as "rotating slightly" or "wiggling in and out"?

Is the clutch nut still tight?

I'll certainly check when I start reassembly...'cause as you can see in the picture some of the primary gear teeth are definitely behind the clutch basket.

Hmmm....

allan.

It's not the translation...especially since I doubt there is any definition for "rocking the clutch" anyway Tongue

I'll look closer but it didn't seem possible to me when I was there. I could be wrong...so I'll look again.

Have heard that trick before, removal of the primairy gear from behind the clutch gear. Have not tried though as I have removed both.
