Spot the difference!

Aside from being horrifically dirty, and having a chunk out of the side of it, I found today that my old sprocket cover, which I finally got around to changing, was missing the spring present in the new (clean and shiney Cool

) one.

What does it do? I haven't ridden the bike yet, I'm quite low on petrol. Again. Rolling Eyes

The bike's always ridden well, and the clutch has been OK besides the slipping problem, and I'm sure the lack of this little spring can't be the cause of that. Though I wish it was. Laughing

it looks like a spring to "pull" back the clutch cable to make sure that the clutch is fully engaged. not sure it would cause clutch slip but i'm not writing it off. i'm sure that kickstart could claify

Yeah, the mechanism of it seems to be that it will pull the wire further into the sprocket cover. I'm not quite sure on how the wires work when it's all shoved together, so I don't know how the missing spring is significant. Confused

Just to clarify; in the old sprocket cover, the thing which the clutch cable hooked into moved freely either way. No resistance.

Your clutch cable pulls upwards (left in the pic) and the worm drive moves out to push the clutch pushrod and operate the pressure plate against it's springs.

When you let go of the lever, the pressure plate will push the pushrod back and close the worm up again. The little spring is just an extra to make sure the worm returns to 'rest' and the slack in the cable is taken up, otherwise you'd get a floppy lever if the worm got stuck up with chain gunge or what-have-you.
