Hi all dose it look like this is all intact apart from what I presume is a bracket missing off the back and where this bracket should attach too?

Cheers

There is a strip that bolts to that bracket and also under the battery carrier - your battery carrier should have a countersunk hole in it for that purpose.

It looks like the lug has broken off your chain case, that this bracket that bolts on it to the battery carrier.

Thanks again guys mine hasn’t got a battery carrier as no Dynamo so I will fabricate something to suite now I know, any ideas how wide the spacer is between the engine mounting plate and the back of the chain case?

Cheers

Don't forget the 3 screws that hold the inner case to the crank case are a special type of screw with a looking washer.

They are featured in your bikes parts lists close by the bracket you were not aware of. I don't think you have a parts list.
The screws are 1/2 long 0 BA thread. the locking washers hold them in. I was following a mate one day and saw a lot of black smoke coming from his rear wheel he was lucky not to come off. His screws had come out, breaking both chains locking the wheel up. His dynamo armature was also bent. I think he had dome head slotted screws, and no locking washers..

Great thanks, the bolts look like that but the washers definitely don’t so thank you again 👍

I use loctite on these as well as the locking washers.
