    I am doing some (rather inept) repainting, have got a quote for rechroming / nickel plating, designed an oil pressure indicator to replace the (incorrect) pressure gauge etc etc, although the real work will start when winter draws on.

    I'm very impressed by the way it has been designed in general although as always with old bikes the rationale for some of the decisions escapes me.

    These are the clutch components:

    I've also (against wiser counsel) rebuilt the 3-brush dynamo to work correctly rather than converting it to 2-brush operation and explored the wonderful internals of the headlight / charging switch:

    holy cow... a wiring diagram built in that's probably worth a few pints on a club night....

    Because they are the sort of comments we get from new users who are not real people, have no interest in motorcycles, put no details in their profile and never return to post anything of interest. The genuine poster then gets tarred with the same brush.

    Aye, but it doesn't show where to top up the smoke.

    Very true. The bikes will all be scrap when all those with the knowledge peg out.

    Not me - previous owner. Mind you by the very amateurish aerosol blowover on the frame s/he probably drank it all themselves.

    Never dealt with a cork lined clutch before so yet another learning curve.....

    Depends on what you post next...

    What bikes have you got or ridden or have in mouldering heaps - that sort of thing establishes your bona fides

    Depends how many slices you get from a cork.

    I was assessing the thickness of each slice and that none appeared to have a corkscrew hole in it.

    Default Progress with oil pressure indicator

    Getting on with this in between other things.

    Main components:



    Assembled:



    I wasn't very successful with reaming the bore so after delving into my old copy of The Motorcyclist's Workshop decided to try lapping with a slave bit of brass - fine grinding paste followed by metal polish:




    This produced a good finish but I'll have another go later. Off to pick up some brass for the piston / indicator rod as well as some ptfe which I'm going to attemnpt to use as a seal. I have no experience with machining this at all so disaster probably awaits.

    Yes indeed.

    Cosmetics done, valve lifter and oil pressure indicator manufactured, engine top end overhauled, electrics sorted (including getting the 3 brush dynamo to work properly) and rewired, primary drive built & rebuilt several times, timing cover fitted & refitted about 30 times to (hopefully) cure (or at least limit) oil leak, new mag sprocket made by Humbernut of IKBA (still some eccentricity somewhere) plus innumerable small jobs I've probably forgotten.

    With a bit of luck it might be running by the end of the month although holidays, a funeral and consequent probate stuff as well as "normal" life have been delaying me somewhat.

    I will pop some pictures here when it's all together but some of the work in progress are here: http://s43.photobucket.com/user/ians...?sort=2&page=1
