I fixed mine with a kit from Cappelini in Italy
I think you mean this:-

The problem is that the original has worn the central part of the sprocket flat in one place.  And it no longer turns
see pic..

I have a used one on the way, but a new one is preferred.  I think this is going to be a pain in the rear to put back together and get the cam chain threaded thru all those parts.

I am not familiar with these models at all, but is this what you need?  It's from CMSNL in Holland, and I'm assuming it is original kit. Mike.

There are several new ones about.  Either in Europe or the USA.  Having bought stuff from both these places in the past, I know just how much extra tax gets applied to the price.  Its been vat, import duties and the extra postage from the port of entry to the front door.  It could add an extra £60+ quid. 
I was surprised DSS did not have one.  If I wait a few weeks, there might be a new one popup on eebay for less than £200.

Still..... at least the engine dident go bang with a snapped cam chain.  I might have had something to moan about then.

I sold my lovely bomber project earlier this year with all of the cam chain stuff NOS.

However, earlier on I got these before I found a NOS one ...needs reassembling but sprocket is really nice.

£20 plus £3.50 post if interested ..less than I paid when I bought. Needs a good clean though.

You'd be surprised ... still got loads .. but Bomber and CB72 were never going to happen realistically.
Member here has the bomber anyway so still in the 'family'

The tooth form on that one looks immaculate Ash.

It doesn't appear to have any wear visible at all, a very good example that would essentially offer a virtual NOS part when cleaned.

It may well be a NOS sprocket Nigel...I did swap a few for Capellini's ones....then I got a NOS one ...all back in the dark days of lockdown.

I dident look to close either...... the £192 quid made me move on quickly.  I was expecting something for £50 from dss.

Just thought I should post a pic of the offending bike.  I dident think I would need to pull the engine apart.  So there we go.  Its not a K0.

I did actually get the top exhaust from dss. And the bottom one from Germany (I think).
