Ash, slightly off topic but I have a hard copy of the CB250RSA dealer set up manual if you would like to scan and download it? I no longer need to refer to it as the bike is finished, photos to post once it has been MOT'd on Saturday. I also have a hard copy of the parts list for the same bike, not great quality as they were taken from the microfiche but good enough to scan.
I'd be happy to pay the return postage as I realise the excellent job you are doing to add to the Dropbox collection takes considerable time so happy to contribute in some way.
