Just another thought, how thick is it?

As for the ring, go to Cox and Turner
They aren't the cheapest about but John Cox is the most helpful person I've ever dealt with and the service is excellent. It shouldn't be much more than 7-8 is the ring is a standard type.

Hi Andrew thanks for the advice It sounds expensive, think it might be cheaper to replace it. I dont know of anywhere near me that could do that sort of work, There doesnt seem to be any kind of engineering in Berkshire now.  Ive managed to source a replacement oil control ring, though I will need to file a small amont from one of the ends. 
 If you mean the valve chamber then its about 3/8ths inch thick at a guess?

Hi when i know for certain that mine is okay then i will have a spare but due to other commitments it will be a few months before i know as every time i part with my spare i end up needing it, but once my series2 is finished i will be able to let you know.
In the meantime if you get stuck in the unit next door to me is a firm with a highly skilled welder who if anyone can repair it will be able to at reasonable cost, only a couple of hours from you , i can get you their number if you decide to go this way.

Hi s1g, thanks for that, pass on the number via PM if you wish and I will bear it in mind. Contacted Mr C today, He can supply Gaskets, Replacement oil control ring and possibly a good cylinder head, Will have to call him back regarding the valve chamber.... It was one of those days where I should have stayed in bed!

Ok i'll ask him what it is next time i see the boss,You'll need to ask John about getting Ivor to weld it, you wont get any sense out of ivor direct, but he is the best welder ive ever seen, and i know he can do cast.

Cheers guys for the help and advice today, really appreciate it.
The day didnt start too well and went down hill rapidly, Just had to walk away from it in the end. Spent most of the afternoon asking myself 'why me?' Still, back to work tomorrow, where its wacky races all day on the M4!

It might be worth asking Cox & Turner about repairing the crack if you cannot get a spare. It is the sort of thing they do.

Hi Guys, Have sent a few emails with pictures to a couple of places that weld cast and re-machine the surfaces, just waiting to hear back, I will post details of companies that offer a reasonable price. If I get a replacement then this will still be worth repairing as it is such good condition.... except for the crack!

Moved onto the air cleaner next... Once apart, I found this... I believe it to be an Original Horse Hair filter? As described on the brass label of the air filter, anybody confirm?

just check with those carbs that there isnt much sideways play on the butterfly shaft as this will alow air to be drawn in causing rough running.

There is virtually no play in the shaft at all on this one, The series 2 I did last year had quite a bit of play in it. It was fixed using a small piece of tin, cut and rolled into a tube which slid over the butterfly shaft thus removing the play.

Will be visiting Hortiman this week to hopefully get the remaining parts needed for the engine... Once I have all the bits then its just a case of cleaning and re-assembly. Hopefully in a week or two it should be running.
Im not going to paint anything until the engine is running, then I can check the bearings, clutch, gears, chain and rotors are all working ok. As we are all aware with the cost of getting parts for these older machines the restoration will be "only replace if its neccessary!"

After travelling the width of the country..... and back! I now have all the engine parts required for this restoration. Chris aka Hortiman kindly invited me over to his, and has provided me with valve chambers, exhaust and piston rings and a few other goodies! Huge thanks Chris Thumbs%20Up. I then travelled East to deepest darkest Essex to the Gent who previously owned this machine. He was able to provide a cylinder head in great condition, a complete spare BJ engine and a spare Series A Wico magneto.... The spare engine has been stripped for some parts namely a good valve guide, as most seem to be excessively worn. I have managed to find an Engineering works based in my home town, they have the replacement valve chamber from Hortiman, and are currently pressing out the worn valve guides and fitting 1 new guide (exhaust) and 1 good used guide (inlet). I decided to send this work out as I do not want to damage another valve chamber!

I took the engine off today. This will enable me to clean the flywheel fan and the back of the engine easier. I will also have access to the clutch bell housing, as on the previous restoration I found an inch thick layer of congealed grease, mud and oil when replacing the clutch plate... This one was no different. However the clutch itself came off easily on this one. Here are a couple of pictures, the first shows the bell housing after scraping out the goo.... and being sprayed with degreaser. The second shows the clutch plate, not too bad, but a little worn. A new one will be fitted soon.

The Magneto also had a makeover today... Its previous owner had a polythene bag wrapped over to keep it dry... It ended up being wrapped around the impulse spring, preventing it from springing.... Now been fixed and what an awkward job retensioning the spring was? Needed 3 pairs of hands! Here are some before and after pictures. Were these painted or left aluminium?

If you ever struggle to get a clutch off like you did on the last one ivefound an internal puller attached to a slide hammer makes quick work of getting them off when stuck.

I have a 3 arm bearing puller... I undo the bolts on the arms, invert them, replace the bolts and put all 3 arms inside the centre of the metal clutch plate, wind up the centre thread and bang, its off! The last one had been stood up to its axle in water and the clutch was rusted to the centre shaft, I tried heating it up, freezing it, several different penetrating sprays... In the end did the above and left a reasonable amount of tension on it overnight.
