Well worth making sure there's a good amount of sticky lubricant in there. I bought a couple of large aerosol cans of "chain and gear lubricant" some time ago and it's ideal for jobs like this because it doesn't dry out or run off and is resistant to water and heat.

(I've also noticed that if you take the bike out of gear and let the clutch out it makes the traffic lights change from red to green. OK that might just be a coincidence).

Ceramic ball.  That is awesome.  Now I have another project as I won't be able to get that out of my head!! ;-)

Thanks for a much needed laugh on a Friday afternoon.  ;D

Tied a ball; doesn't work. Makes everything too long and you can't put the adjustment bolt in on the trans side.

If I hold the lever in with it not running and kick it over the clutch is 'free' but it has some drag. On my 5 speed if I do this the clutch spins freely with no drag. Something is amiss in the clutch basket I now believe.

I’ve heard tales that some “mechanics” have fitted a plate too many in the clutch basket.

It’s possible this has happened with yours and the ball has been left out in an attempt to rectify the situation. It needs stripping out whatever.

Also, the steel clutch plates could be badly warped, or the dished plates on both ends could be installed wrong.

Watch out for those six 7mm clutch spring bolts. They are made of cheese, and twist the heads off real easy. Hard to find replacements.

Okay fellas, maybe I've found something.  8)
The center steel plate, item 12 in the diagram.

I've had it out and put it back in the same way each time. I remember thinking it odd that it seemed to have a 'dish' to it. Now I'm staring at it thinking it really should be flat, right?

See the gap between the ruler and the plate?

One pic each of either side. If someone can confirm that should be perfectly flat then I shall dance in happiness and glee. Until I realize I have to order one anyway.

Only the outer and inner steel plates should be dished, and they are obviously very dished only in the center.

All the other steel plates should be perfectly flat. They are very often warped like that, and if you have a dragging clutch it will overheat and warp the steel plates.

I would order a few extra steel plates because new ones are warped from the factory about half the time.

Thanks Ace! I suspected as much. It is so perfectly formed that I thought it was made that way when I glanced at it before and just shrugged and put it back in. I was so convinced the problem was elsewhere. I could bang my head against the wall for all this nonsense I've gone through.
Four pounds thirty on Hitchcocks for one.

We have a USA based spares supplier on the forum don't we?
Are you not better buying from him? must be cheaper shipping.

On your suggestion I did check Western Cycle Supply's web site. Which is, frankly, horrible. No clutch parts came up in a search, just handlebar levers.
I compared the price of another item with the same on Hitchcocks and there was virtually no savings other than the probable shipping cost.
Hitchcocks does such an amazing job, has a fabulous web site as well as a beautiful and easy to use catalog it will take much better pricing and/or a vastly improved web site to get my business.

David, you're becoming the clutch expert!  Wow man, good catch.  It's hard to see from the pics, but it is a bit bowed.  Now I can't wait to see if this is it. 

Exciting.

I also emailed Hitchcocks to confirm it should be flat as I knew they would know or could look at one. Indeed, should be flat like a coin.
Also regarding the above about where to buy it I'm not just ordering this one part. I need some things for my own bike as well so I can split the shipping on this one with my 'customer'.

You're preaching to the converted  ;D
I'm in the UK and have been a Hitchcock's customer for many years.

I’ve helped pay Mr. Hitchcock’s mortgage for the last three years. It had to be said they do give a very rapid turnaround of orders; in fact exceptionally so.
