    Got all the parts stripped down (bearings knocked out etc) for blasting and painting.
    Should get the 2 broken studs out on Friday.
    I ordered new wheel bearings and tubes/tyres too.

    You got a follower here also.

    And that trick with the nuts always works. At least every time I try it. It's my go-to method of struck bolt/stud removal.

    The donor does look like it had a hard life! Hopefully the engine looks better on the inside than the original one, that certainly is some terminal damage!

    Thanks.
    I think the heat from the welding helps slacken the stuck bolts too.

    I don't plan to use anything from the engine of that donor bike. Just the wheels, forks and yokes.
    I have everything else I need (except the funds to do it!) so it will get built up as and when.
    I hope to get the crank and cases back in the next couple of weeks, and I already have another head and gearbox/clutch assembly but need to save up for the rebore and new pistons. After that all I need to source are all the brake refurb parts.

    Some time in the future I might get stuck into the donor bike but I already know it will be a nightmare.
    Still, I have started from worse/less.

    I worked in a shop for a couple of years after I retired that overhauled radial aircraft engines. Broken studs were a regular occurrence. It was what we did to remove them, the boss was very good at it. Never saw him fail once. The heat also expands the aluminum to help release the stud. Almost don't need the wrench to remove them. Of course everytime he did it he said "to err is human to repair is devine"

    2 steps forward, one step back...

    I ordered a pair of Dunlop TT100 tyres last week but 2 x rear tyres turned up this week. I called them today and they will send the missing front tyre and uplift the other tyre.
    Then I went to collect the wheels etc from the powder coater but found they had roxxed it up and painted certain parts black instead of silver, one part matt black instead of gloss black and they had not masked the wheels or yokes as instructed.
    Still, they will make good and I'll collect them tomorrow.

    I did get the instrument bracket back as it was correctly done in satin black so I built up the instrument console with all new or restored parts.

    I also built up the cush drive with new bearings, sprocket and lock tab washers.

    The crank should arrive here early next week, but the crank cases are still being sorted out and will take another couple of weeks to arrive.

    Got a pile of stuff back from powder coating yesterday so today I started building stuff up.
    New bearings and spacers in the wheels, new discs on the wheels and fitted the yokes and lock stops. Oh, ad fitted a new steering lock.
    Not much more I can do for a while until I get the front tyre, crank and cases back.

    The front tyre arrived this afternoon so I'll get them fitted this week.
    I went with Dunlop TT100s as they were original fitment.

    What are the disks made of? On the previous picture they just looked like rusty cast iron, but here they look different.

    Brand new cast iron, but they have a weird brown coating. I queried it with the Italian vendor but they said it was done the same way as the factory did it.
    It'll soon scrub off in the swept areas and will protect the unswept areas from rusting (for a while) and may be less obvious then.
    Otherwise I'll be attacking them with wet & dry.

    Ah okay, I was wondering if it was some kind of coating on there. Guzzis also use the old cast iron instarust rotors.

    All big Italian bikes of that era used cast iron Brembos.

    Benelli, Guzzi, Ducati, Laverda.

    Cast iron rotors give better performance than stainless steel. Bike manufacturers don't like to use cast iron because of the rust, appearance issues.

    I switched to larger stainless steel discs on my own bike and found them better.
    Larger diameter, modern m/c and sintered pads all add up to make a big difference.
    Back in the day cast iron discs were better than Jap stainless discs with cardboard brake pads though.

    Tyres now fitted, that was my workout for the day!
    I'm more used to fitting tubeless radials so these crossplies were hard work. Especially in 3ÂșC workshops...

    Bit more done today.
    The new instrument looms arrived from Japan so I built them up and loosely fitted the instruments.

    Then the crank arrived and it looks fantastic. The wooden crate I made for it survived the 2000 mile round trip.

    The crank cases are still away being repaired and need to send off the cylinders for re-boring and new liners (when funds allow).
    I have also enquired into cost and lead time for rechroming the fork stanchions.
    Hopefully by the weekend it will be back on 2 wheels.

    Received the inner tailpiece (in carbon fibre for a bit of bling) and test fitted it using a spare tailpiece that was lying around.
    It is one of THE most fiddly jobs on the bike as the tailpiece is adjustable in 3 axes and then the hinged seat arc of movement and clearance to the tailpiece has to be factored in.
    Easy to rush this and the end result is it looks crap.
    It was just a quick positioning as I need to fit the seat hinges first, and also restore the seat lock mechanism so the seat is in the final position before doing final fit of the tailpiece.

    Just a few small things but it's starting to come together.
    Received the rear indicator stems and ignition switch at last.

    Also dug out front and rear spindles and associated spacers and adjusters and managed to fit the rear wheel.

    [​IMG]2019-01-26 13.15.24 by Grant Duguid, on Flickr

    Might take a while before fitting the forks as I need to send them off for new chrome, and that takes around 6 weeks, bummer.

    Just found this, love it!

    I'm surprised that nobody has mentioned the short work of fiction which ran in Motorcyclist magazine in the '80s about the Jota racing the Devil.
