    Hey Manin.
    Thanks for your input.
    I have a complete parts manual, and the workshop manual on it’s way!
    It looks like the cam gears need to be pulled from the cam shafts, and then the shafts can be removed by sliding out to the drive side now that the LH casing has been removed.
    On a footnote, the shells in the big end, and the journals on the crank look perfect! I will still replace the shells, rings etc on rebuild...

    A few ideas, if the camshaft lobes are ok and you are going to reuse them leave them in the cases, if not then buy the correct puller and remove the gears to be able to slide cams out. As for refitting the cam gears as they are a very tight fit you can use blocks of wood to rest the l/h side of cams so you can tap on the gears and it also helps if you warm the gears up before fitting or the other option is to use emery paper on the inside of the gears until they are a push fit.

    Thanks again Martin.
    I have now received the correct socket for the LH cam gear nut (what a very odd size - 1.1 inch = 28 mm!), and as the crankcases need replacing, they do indeed need to be removed… The corrosion in the lower part of this bike is a nightmare: lower engine mounting shaft and spacers totally seized in frame, spacers and crankcases; frame pitted, rust on one part of rims, and even the RH fork to spindle clamp still requires work (and heat) to remove it fully. Had I seen/realised just how bad it was, I probably should have driven away or dumped en route home!! Not giving up now though..!
