    So the Daytona restoration has to take a back seat for a few weeks as i strip n build a new motor, the motor was supposed to have been rebuilt awhile back lol and the problem was a flickering oil light on tickover but ran real nice otherwise. So out with the oil switch to test another only to find loads of sealer floating around in the oil :-( at this point i decided to remove the timing cover and that's when i decided to rebuild the motor myself as this is what i found, some twat had fitted the intermediate spindle the wrong way round :eek: Engine out and full strip n check and it looks like a few new parts and i will have a nice motor to fit back in soon :)

    Progress at last, engine stripped and new parts sorted. Managed to get the incorrectly fitted intermediate shaft out and the badly fitted camshaft bearings out today so the cleaning and rebuild can start :)

    At last, managed to sort out a special tool for reaming the camshaft bushes :) hope to start some rebuilding work soon.

    It's looking the dogs bits (as your rebuilds always do) darkman.
    Will you be taking the opportunity to relocate the gear change onto the correct side? :cool: :p

    Respect!
    Coz I can never easily swap sides without hysterical consequences for those watching :rolleyes:
    A mate used to own an early Enfield 500 Bullet.
    Not only was the gear lever on the "wrong" side.
    It was 1 up & the rest down. I swear he only allowed me to ride the feckin thing when he needed a laugh! :confused:

    Lol, BSA twins of old are the same, up then down. I guess as i ride both classic and modern bike regularly it's imprinted in me head somewhere :)

    Darkman, do you mind me asking if your cases were shot, bead or aqua blasted? And who did them, please?

    Many thanks,

    Adie

    I do them myself Adie, i use a coarse glass for any areas i repair or detail and fine glass beads to clean and finish off. If you are paying someone to do some work for you go for aqua blasting :)

    Hmmmm - OK, thanks for the reply and advice. Most helpful and much appreciated.

    Did you make your own blast cabinet or buy a proprietary one? I've got a LOT of restoration work to do so I'm thinking of getting my own cabinet for the run of the mill stuff (no pun intended) and use commercial/specialist aqua blasting for the motor internals or delicate parts, etc.

    I imagine even a medium msized cabinet would pay for itself eventually - depending on the blast media costs!

    Thanks again, Darkman - and my compliments on the work. Looks amazing.

    As my workshop is alot smaller than my old one i just make a frame out of dustbins and hang sheets from it outside lol i did have a big cabinet at the old workshop and it was far easier.

    Another job done, wish i had done it with the engine out as its far easier on its side but makes the engine to heavy for me to lift in then, fought me all the way but gearbox is back in and cams timed up.

    That looks fantastic! And SO nice to see that you're using cross head machine screws rather than Allen screws in the case covers! Can you still get the proper, original style cross head case screws or did you salvage those?
