    With apologies to the late, great Boyd Coddington I have borrowed the title of this project from him.
    Project Junk Yard Dog is born.

    This will be another very slow project as funds and time allow.
    I bought the bike as a donor for project 007, the red 1200 I completed recently.

    [​IMG]2017-11-01 12.32.19 by Grant Duguid, on Flickr

    It yielded forks, yokes and wheels, all period correct for 007.

    The rest of the bike was in such bad condition I seriously considered breaking it for spares, but it pains me to do that.

    Broken fins

    Weird brackets added all over the place

    Broken and badly welded crankcases

    Home made oil filler spout

    [​IMG]2017-11-06 12.48.20 by Grant Duguid, on Flickr

    Looked like it came with a trick swingarm

    [​IMG]2018-03-13 10.26.05 by Grant Duguid, on Flickr

    Turned out to be brazed on out of thin conduit and once the paint was removed it started to fall apart

    [​IMG]2020-05-04 09.27.28 by Grant Duguid, on Flickr

    Also has a 1200 frame but a 1000 engine, and no papers... And yes, I overpaid for it as I was told it had (becoming) rare 4C cams (it didn't).

    First of all I need to sell a couple of bikes (hard in the current situation), then I can use these funds to start on this.
    I already have a decent set of 1200 crankcases and another cylinder block.
    I have the chance to buy (when I can afford it) the GSXR wheels, discs and 4 pots that I bolted on today.

    [​IMG]2020-05-04 09.44.37 by Grant Duguid, on Flickr

    So, what's the plan?
    Not sure yet, but I'm thinking of making it as light as I can, as minimal as I can and to hell with standard.

    My gold bike (POP) and my blue bike (Phoenix) already have the more modern tyres, wheels, discs, calipers etc so I know how good they make the bike.

    I would love to add a digital speedo, one-off bodywork and added lightness everywhere.

    Why do I do this? Why not?

    The piece of box section square tubing had been welded to the frame and wrapped in an old inner tube. This acted as the rear rubber mount for the non-standard tank.
    The front mounts (standard) were too far forward so a second set of mounts had been welded on around 2 or 3 inches rearward.
    The tank looks ok so I may re-use it, other than the fact it needs new mounts front and rear and 2 x fuel tap openings (which I already cut out of a knackered standard tank). There is only a single fuel outlet and the tap diameter is pitifully undersized.

    [​IMG]2017-11-05 10.37.57 by Grant Duguid, on Flickr

    Thought about adding a tank rack, undecided.

    [​IMG]2017-11-08 13.54.30 by Grant Duguid, on Flickr

    There was lockwire everywhere on this, can only assume it was some sort of track rat bike.
    Even the rear shocks were an inch shorter than standard.

    I had a standard swingarm powder coated (and new bearings) after cutting off the original torque arm lug.
    The wider tyre would be hard up against it otherwise.
    So for now it is wearing the shiny new swingarm, a floating rear caliper bracket and torque arm mounted to the frame.
    The sprockets are offset 520 instead of the original 530 or 630 depending on the model.
    Basically a 530 front sprocket machined on the inside to effectively offset it quarter of an inch.

    I'll be curious to see what this project becomes.

    Lots to do, but that often comes with freedom, which makes the project even more interesting.

    It will all boil down to how much dinero I can put into it.
    I don't want to tune it to the max or throw money at it but obviously it will need the crank rebuilt, rebore/pistons, head job, electrics, ignition, instruments and bodywork.
    My task will be to avoid stereotypes, easy options and shortcuts.
    It won't be Hipster, no brown flat seat, exhaust wrap, knobbies, or chequered tape here.

    It's got a lot of character as is, in my opinion. I'm not saying don't change it, because I definitely like your work, but it's got a cool, if rough vibe. It feels somewhere between Mad Max and road racer. Also, thank you for saying what it won't be... Everything you've listed is terrible right now in the 'custom' world.

    It's now possible to buy 4 valve heads, fuel injection, Nikasil bores, Carrillo rods for the crank. Takes redline from 8K to 11K, and bank balance down by around $15K.
    It will always be rough and tough without going down that route either.

    Just a few things today.
    Dug out a carbon fibre headlamp shell I have had waiting for the right project.
    I'm also getting a carbon alternator cover.

    [​IMG]2020-05-05 12.39.21 by Grant Duguid, on Flickr

    That box section abomination has been doing my head in, had to go!

    [​IMG]2020-05-05 12.46.32 by Grant Duguid, on Flickr

    Thinking about a carbon single seat too, hoping one arrives in the post soon.

    The aim is to get it as light as I can without spending silly money on it.
    Lots of carbon and cutting of unnecessary brackets will help.
    The GSXR wheels/discs/tubeless tyres etc save around 4.5kg over standard too.
    Normally these bike weigh around 235kg so if I can get it down to around 200kg that would be as far as is possible with a standard frame.
    Guess it's time to get the file and electric drill out then.

    Tried the tank on again, both with and without the square section piece.
    The tank doesn't touch anywhere on the frame, maybe it was needed when the carbs were in place.
    Anyway, the square section is history.
    Fitted some tank rubber mounts to see how it looked.
    I think it has potential, plus it's lighter than a stock tank. And bigger.

    Resting on square section

    Oh, and my NALOC T-shirt and stickers arrived today.

    If anyone can square this bike away, you're the guy to get it done! Look forward to watching it happen!

    It's just time, money and effort.
    At the moment I only have one of these things.
    I'm also interested to see which direction it goes in.
    So many ideas...

    You said that you didn't have any docs for this, how easy will it be to get registered?

    No problem in the UK. Declare to NOVA. Age verification from a dating specialist. MOT then insure on chassis number. Send off paperwork and fees to DVLA. Receive V5 then buy numberplate. Sorted.

    Just playing around today with some stuff I have lying around.

    Rear mudguard (modified) from an RGS

    [​IMG]2020-05-06 08.32.58 by Grant Duguid, on Flickr

    Fairing mount from a late Jota

    [​IMG]2020-05-06 08.33.35 by Grant Duguid, on Flickr

    Tailpiece from an FJ1200

    [​IMG]2020-05-06 08.38.03 by Grant Duguid, on Flickr

    Tank rack on the tail

    [​IMG]2020-05-06 08.42.28 by Grant Duguid, on Flickr

    I'm sure the final result will incorporate little or none of these but at least this stage is very low cost!
    Rummage through the oddbins and mix and match.

    Still digging out parts for potential use on JYD.
    It officially has it's own bin now to store stuff I decide to use on it.

    [​IMG]2020-05-07 11.15.19 by Grant Duguid, on Flickr

    The sprocket cover/clutch actuation pivot/selector mechanism on the bike has been cut down so much it is useless to me. One (top) screw fixing point has been cut off so the whole casing could dangerously bend outwards when the clutch is pulled in. As this is oil bearing I don't even want to go there.
    So, I have another casing that had previously been 'modified' (and so not to be used on a standard build) and this will be further modified before being put to good use.

    [​IMG]2020-05-07 11.12.03 by Grant Duguid, on Flickr

    Also in the above photo is an m-Unit that I have spare. This will allow dramatic simplification of the wiring loom on the bike. No fuse box, much less relays and several other benefits.

    Just for shits and giggles I fitted the carbon headlamp cover. That fairing bracket HAS to go!

    The sidestand that was on the bike had been drastically shortened to the point that the bike lay at a roughly 45° angle.
    Enough of that crap.
    I fitted a Kawasaki sidestand plus special adaptor bracket. The bracket is a development of a development by a few individuals and works very well in conjunction with the Kawa stand (sourced from breakers).

    [​IMG]2020-05-07 13.27.48 by Grant Duguid, on Flickr

    I had to try the tank with carbs fitted, and yes, the fugging things touch the underside of the tank now I have removed that square section monstrosity.

    [​IMG]2020-05-07 13.29.13 by Grant Duguid, on Flickr

    [​IMG]2020-05-07 13.28.10 by Grant Duguid, on Flickr

    I have 4 options:
    - refit or adapt another bracket to raise the rear of the tank
    - cut and shut the tank
    - fit a standard tank
    - fit angled inlet stubs

    Need to think about this, although a standard tank would save a lot of faffing.

    Standard tank would lend itself to the FrankenVerda vibe I think.

    Yes but too samey. Ideally I would like this to be as different as possible to other Laverdas.
    I have another style of Laverda tank, will try it tomorrow
